Hubert H. Humphrey Metrodome

• The Metrodome was the scene of several players joining the 3,000 hit club, including Eddie Murray, Dave Winfield, and Cal Ripken Jr.
• The Metrodome was the site of Dallas Cowboys running back Tony Dorsett's 99-yard run, on January 3, 1983, the longest run from scrimmage in NFL history, in a Monday night game that was won by the Minnesota Vikings.
• Dwyane Wade recorded the fourth triple double in NCAA men's basketball tournament history on March 29, 2003.
• On June 28, 2007, at the top of the first inning, Frank Thomas hit a three-run home run to left-center against Carlos Silva for his 500th career home run. He was later ejected for arguing balls and strikes.
• On September 30, 2007, Brett Favre of the Green Bay Packers threw his record-breaking 421st career touchdown pass to Greg Jennings while playing the Vikings at the Metrodome.
• On November 4, 2007, Antonio Cromartie of the San Diego Chargers returned a 57-yard field goal attempt, which was short, 109 yards for a touchdown, which became the longest play in NFL history. In the same game, Adrian Peterson, running back for the Minnesota Vikings, had 30 carries for an NFL single-game record 296 rushing yards, along with three touchdowns.
• On November 30, 2008, against the Chicago Bears, Vikings quarterback Gus Frerotte threw a 99-yard touchdown pass to Bernard Berrian, tying an NFL record for the longest pass.
• On July 28, 2009, White Sox pitcher Mark Buehrle broke the MLB record for consecutive batters retired. The record was 41; Buehrle retired 45 in a row. His record includes his perfect game tossed on July 23, 2009.
• On October 5, 2009, with a 30–23 victory over the Green Bay Packers, his former team, Brett Favre of the Vikings became the first quarterback in NFL history to defeat each of the league's 32 franchises.[37]
• On October 27, 2013, in a 44–31 loss to the Green Bay Packers, Viking Cordarrelle Patterson returned the opening kickoff 109 yards for a touchdown. This tied the longest play in NFL history.[38] The previous 109-yard play also took place at the Metrodome, as mentioned above.

Metrodome roof (1982–2010)

Metrodome roof (2011–2013)

The Metrodome's air-supported roof was designed by the inventor of air-supported structures, David H. Geiger, through his New York-based Geiger Berger Associates, and manufactured and installed by Birdair Structures.[40] An air-supported structure supported by positive air pressure, it required 250,000 ft³/min (120 m³/s) of air to keep it inflated. The air pressure was supplied by 20 fans of 90 hp (67 kW) each.[41] The roof was made of two layers: the outer layers were Teflon-coated fiberglass and the inner was a proprietary acoustical fabric. By design, the dead air space between the layers insulated the roof; in winter, warm air was blown into space between layers to help melt snow that had accumulated on top. At the time it was built, the 10 acres (4.0 ha) of fabric made the roof the largest expanse ever done in that manner.[42] The outside Teflon membrane was 1⁄32 of an inch thick and the inner liner of woven fiberglass was 1⁄64 of an inch thick.[43] The entire roof weighed roughly 580,000 pounds (260,000 kg). It reached 195 ft (59 m), or about 16 stories, at its highest point.[44]

To prevent roof tears like those that occurred in its first years of service, the Metropolitan Sports Facilities Commission adopted a twofold strategy: When snow accumulation was expected, hot air was pumped into the space between the roof's two layers. Workers also climbed on the roof and used steam and high-powered hot-water hoses to melt snow.[45] In addition, before the storm that caused the December 2010 collapse, the inside of the stadium was heated to nearly 80 °F (26.7 °C).[43]

To maintain the differential air pressure, spectators usually entered and left the seating and concourse areas through revolving doors, since the use of regular doors without an airlock would have caused significant loss of air pressure. The double-walled construction allowed warmed air to circulate beneath the top of the dome, melting accumulated snow. A sophisticated environmental control center in the lower part of the stadium was staffed to monitor the weather and make adjustments in air distribution to maintain the roof.

Because it was unusually low to the playing field, the air-inflated dome occasionally figured into game action during baseball games. Major League Baseball had specific ground rules for the Metrodome. Any ball which struck the Dome roof, or objects hanging from it, remained in play; if it landed in foul territory it became a foul ball, if it landed in fair territory it became a fair ball. Any ball which became caught in the roof over fairground was a ground rule double. That has only happened three times in its history – Dave Kingman for the Oakland Athletics on May 4, 1984,[46] the University of Minnesota Gophers player George Behr and Corey Koskie in 2004. The speakers, being closer to the playing surface, were hit more frequently, especially the speakers in foul ground near the infield, which were typically hit several times a season, which posed an extra challenge to infielders trying to catch them. However, beginning with the 2005 season, the ground rules for Twins games were changed such that any batted ball that struck a speaker in the foul territory would automatically be called a foul ball, regardless of whether or not it was caught.

The dome's roof color made it close to impossible to catch balls without taking the eye off the ball. As a result, fielders frequently lost balls in the roof. An example of this is seen in a home run derby put on by a softball entertainment crew before a Twins game. Taken at the field level, the balls generally tended to be lost in the roof.[47]

Five times in the stadium's history, heavy snows or other weather conditions have significantly damaged the roof and in four instances caused it to deflate. Four of the five incidents occurred within the stadium's first five years of operation:[48]

On November 19, 1981, a rapid accumulation of over a foot of snow caused the roof to collapse, requiring it to be re-inflated. It deflated the following winter on December 30, 1982, because of a tear caused by a crane used in snow removal. This was four days before the Vikings played the Dallas Cowboys in the last regular-season game of the 1982 NFL season. In the spring following that same winter, on April 14, 1983, the Metrodome roof deflated because of a tear caused by late-season heavy snow,[49] and the scheduled Twins' game with the California Angels were postponed. On April 26, 1986, the Metrodome roof suffered a slight tear because of high winds, causing a nine-minute delay in the bottom of the seventh inning versus the Angels; however, the roof did not deflate.

Birdair had conducted a regular inspection of the Metrodome roof in April 2010. Its report to the Metropolitan Sports Facilities Commission stated that "the outer membrane is in good condition and still holding up well", and rated the inner liner's condition as "fair to poor".[50] The inspectors also noted that the inner liner of the roof was dirty (mostly due to emissions from automotive events) and had some holes in it, advising that the holes be monitored to avoid large tears from enlarging. Also, Birdair noted some minor areas on the outer membrane that needed repairing, which was done by the time of the commission's July regular meeting. Overall, Birdair noted the membrane was weathering as anticipated and had exceeded its service life of 20 years; it recommended planning for replacement of the roof fabric and noted that planning and implementation would take an additional five years and cost $12–15 million.[50] In forming their own conclusion, the Metropolitan Sports Facilities Commission staff decided that the outer membrane was in very good shape and that the roof continued to have serviceable life, and planned to schedule another testing in four years; the commission made no recommendations.

The deflated roof, a day after heavy snow and high winds from the December 11, 2010 blizzard caused it to tear and deflate

A severe snowstorm arrived in Minneapolis in the late evening of December 10. The snowstorm lasted to the following night on December 11, with 17 in (43 cm) of snow accumulated across the city.[51][52] Due to strong winds, hoses malfunctioning, and a hazardous slippery layer building up on the roof, workers were not allowed to remove the snow from the roof. As the workers were pulled back, many noticed that the roof's center was sagging down by the weight of the snow.[43]

At around 5:00 a.m. CST on December 12, three of the roof's panels tore open.[52] Snow fell through, covering the turf field. The night before the incident a Fox Sports crew, who were setting up for the football game between the New York Giants and Vikings, noticed water was leaking through the roof. They decided to leave their cameras on; the cameras captured footage of the roof deflation and the snow dropping to the field.[43] The footage was aired on Fox NFL Sunday and quickly went viral.

The game between the Vikings and Giants, scheduled to take place on December 12 during the afternoon, was postponed to the next day and relocated to Ford Field in Detroit.[52][53] There were considerations moving the game to the University of Minnesota's nearby TCF Bank Stadium. However, the stadium had limited seating capacity, as well as snow that would have taken several days to clear.[43] A couple days later, a fourth panel ripped open, allowing more snow to enter the stadium.[54] This forced another game between the Vikings and Chicago Bears (originally scheduled at the Metrodome on December 20) to be relocated to TCF Bank Stadium.[55] The final two games for the Vikings for the season were on the road, and the Vikings were already eliminated from the playoffs, meaning no additional home games were to be played.

The roof collapse also caused schedule complications for the Golden Gophers baseball team. All Big Ten Conference home games were moved to Target Field, the home stadium of Major League Baseball's (MLB) Minnesota Twins. A Metrodome tournament was replaced with a three-game series against Gonzaga. Another tournament named the Dairy Queen Classic was relocated to Tucson, Arizona. Other changes included many home game cancellations, and some games being pushed to next year's season.[56]

New roof in early August 2011

On February 10, 2011, it was announced that the entire Metrodome roof needed to be replaced at an estimated cost of $18 million.[50][57][58][59] In November 2010, the University of Minnesota men's baseball team had announced plans to play all of their 2011 games at the Metrodome; however, the roof collapse caused those plans to be abandoned. On February 18, 2011, the Gophers announced that all 12 scheduled Big Ten home games in April and May would be played at Target Field, with three non-conference games moved to on-campus Siebert Field.[56]

On July 13, 2011, it was announced that the roof was repaired and had been inflated that morning. However, other construction and repairs were still in progress. The remaining construction and repairs were done by August 1, 2011.[60]

Metrodome field, in its baseball configuration. The football markings are slightly visible under the turf.

During its early years of operation, the field at the Metrodome was surfaced with SuperTurf.[61] The surface, also known as SporTurf, was very bouncy—so bouncy, in fact, that Billy Martin once protested a game after seeing a base hit that would normally be a pop single turn into a ground-rule double.[24] Baseball and football players alike complained that it was too hard.

This surface was upgraded to AstroTurf in 1987, and in 2004, the sports commission had a newer artificial surface, called FieldTurf, installed. FieldTurf is thought to be a closer approximation to natural grass than Astroturf in its softness, appearance, and feel. A new Sportexe Momentum Turf surface was installed during the summer of 2010.[62][63]

When the conversion between football and baseball took place, the pitcher's mound was raised and lowered by an electric motor. The mound weighed 23,000 pounds (10,000 kg) and was 18 feet (5.5 m) in diameter.[3] With the field repair, the sliding pits and pitcher's mound used by the Twins and Gophers were removed. Any future baseball games would see baserunners slide on "grass". The home plate area was kept, as it was not "in-play" for football configuration. The original home plate installed at the dome was memorably dug up after the Twins' final game and has been installed at Target Field. A new field was installed in the summer of 2011 due to the damage from the December 2010 roof collapse.

From 1985 to 1994, the left-field wall included a 6-foot (1.8 m) clear Plexiglas screen for a total height of 13 feet (4.0 m).[3] It was off this Plexiglas wall that Twins player Kirby Puckett jumped to rob Ron Gant of the Atlanta Braves of an extra-base hit during Game 6 of the 1991 World Series (a game that Puckett would win with an 11th-inning walk-off homer) – in later years, with the Plexiglas removed, it would have been a potential home run ball.

Metrodome's "baggie" in right field.

The Metrodome's right-field wall was composed of the 7-foot (2.1 m)-high fence around the whole outfield and a 16-foot (4.9 m)-high plastic wall extension in right field, known as the "Baggie", or the "Hefty Bag". The seats above and behind the Baggie were home run territory; the Baggie itself was part of the outfield wall. Fenway Park's "Green Monster", a comparable but taller feature, is 17 feet (5.2 m) closer to home plate than the Baggie was, so batters who hit short, high fly balls were not typically helped by it. However, it was an attractive target for left-handed power hitters, and it was not uncommon for upper-deck home runs to be hit to the right field. When in a rectangular configuration for football and other small-field events, the Baggie was taken down and the seats behind it extended to form complete lower-deck seating.

As the stadium was designed first and foremost for the Minnesota Vikings, they had the fewest problems. However, the economics of 21st century professional sports meant that the Vikings owners wanted more luxury suites and better concessions. Renovations were rejected twice, with the 2001 price tag at $269 million.[64]

The Vikings played their first game at the Metrodome in a preseason matchup against the Seattle Seahawks on August 21, 1982. Minnesota won 7–3. The first touchdown in the dome was scored by Joe Senser on an 11-yard pass from Tommy Kramer. The first regular-season game at the Metrodome was the 1982 opener on September 12, when the Vikings defeated the Tampa Bay Buccaneers, 17–10. Rickey Young scored the first regular-season touchdown in the dome on a 3-yard run in the 2nd quarter. On January 9, 1983, the Vikings defeated the Atlanta Falcons, 30–24, in a 1st-round game that was the first playoff game at the Metrodome. On January 17, 1999, the Falcons defeated the Vikings in the first NFC championship game played at the Metrodome. On December 29, 2013, the Vikings played their final game at the Metrodome, a 14–13 victory over the Detroit Lions. The team's record at the dome was 162–88 in the regular season and 6–4 in playoff games. They finished with a perfect record at the dome against the Arizona Cardinals (8–0), Baltimore Ravens (1–0), Cincinnati Bengals (4–0), and Houston Texans (1–0), but with a winless record there against the New York Jets (0–3).

NFL owners voted during their May 24, 1989 meeting to award Super Bowl XXVI to Minneapolis over Indianapolis, Pontiac and Seattle.[65] The game on January 26, 1992, was the second Super Bowl to be played in a cold, winter climate city. The first one was Super Bowl XVI on January 24, 1982, in Pontiac, Michigan. Super Bowl XXVI resulted in the Washington Redskins defeating the Buffalo Bills, 37–24.

Pre-game activities at a Vikings game in December 2007.

When opened in 1982, the Metrodome was appreciated for the protection it gave from mosquitoes, and later the weather.[26] Over the years there had been a love-hate relationship with the fans, sportswriters, and stadium.[26][66] The Minnesota Twins won two World Series championships at the Metrodome. The Twins won the 1987 World Series and 1991 World Series by winning all four games held at the Dome in both seasons.[67] The loud noise, white roof, quick turf, and the right-field wall (or "Baggie") provided a substantial home-field advantage for the Twins.[26] The 1991 World Series has been considered one of the best of all time.[28][68][69][70]

For Twins baseball, the address of the Metrodome became 34 Kirby Puckett Place, an honor given to one of the most famous Minnesota Twins players.[3] In 1996, a section of Chicago Avenue in front of the Metrodome was renamed Kirby Puckett Place by the city of Minneapolis.[71] The Metrodome Plaza was added along Kirby Puckett Place before the 1996 season.[3] Before that, the address for the Twins was 501 Chicago Avenue South. For baseball, the Metrodome informally has been called "The House That Puck Built".[72]

By 2001, several newer purpose-built Major League Baseball stadiums had been constructed, and the Metrodome was considered to be among the worst venues in Major League Baseball.[73][74][75]

Only two Twins games at the Metrodome were ever postponed. The first was on April 14, 1983, when a massive snowstorm prevented the California Angels from getting to Minneapolis. The game would have likely been postponed in any case, however; that night heavy snow caused part of the roof to collapse.[1] The second was on August 2, 2007, the day after the I-35W Mississippi River bridge had collapsed a few blocks away from the Metrodome. The game scheduled for August 1 was played as scheduled (about one hour after the bridge had collapsed) because the team and police officials were concerned about too many fans departing Metrodome at one time, potentially causing conflict with rescue workers. The August 2 ceremonial groundbreaking at the eventual Target Field was also postponed, for the same reason. The Metrodome carried a memorial decal on the backstop wall for the remainder of the 2007 season.[76]

The Twins played their final scheduled regular-season game at the Metrodome on October 4, 2009, beating the Kansas City Royals, 13–4. After the game, they held their scheduled farewell celebration. Because they ended the day tied with the Detroit Tigers for first place in the American League Central, a one-game playoff between the teams was played there on October 6, 2009, with the Twins beating the Tigers 6–5 in 12 innings. The division clincher would be the Twins' last win at the Metrodome. The announced crowd was 54,088, setting the regular-season attendance record.

The final Twins game at the Metrodome was on October 11, 2009, when they lost to the New York Yankees 4–1, resulting in a three-game sweep in the 2009 ALDS. The Twins' appearance in this series gave Metrodome the distinction of being the first American League stadium to end its Major League Baseball history with post-season play. The only other stadiums whose final games came in the postseason are Fulton County Stadium in Atlanta (1996), the Astrodome in Houston (1999) and Busch Memorial Stadium in St. Louis (2005), all of which were home venues for National League teams. With the departure of the Twins, this leaves the Tampa Bay Rays as the last remaining major league team to play their games in a non-retractable domed stadium.

When configured as a basketball arena, the fans in the nearby bleachers got a suitable view of the court, but the action was difficult to see in the upper decks. Concessions were very far away from the temporary infrastructure. The Metrodome as a basketball arena was much larger than most NBA and major college basketball arenas, which run to about 20,000 seats; it functioned like Syracuse's large Carrier Dome. However, the NCAA made a significant amount of money selling the high number of seats for regional and championship games for the men's basketball tournament.

Metrodome set up for the 2009 NCAA men's basketball tournament; temporary stands enclose the basketball court on two sides with the permanent stands on the other two.

Ten NCAA tournaments took place at the stadium:

The Timberwolves used the stadium for their home games during their inaugural season (1989–90) in the NBA while the team waited for construction of Target Center to be completed. The team set NBA records for the highest single-season attendance ever: 1,072,572 fans in 41 home games. The largest crowd for a single game occurred on April 17, 1990: 49,551 fans watched the T-Wolves lose to the Denver Nuggets in the last game of the season. This was the third-largest crowd in the NBA's history.

Beginning in the 1982 college football season, the University of Minnesota Golden Gophers began playing their home football games at the Metrodome. The first game was a 57–3 victory over the Ohio Bobcats on September 11, 1982.[77] The Gophers football record at the Metrodome 1982–2008 (27 seasons) 169 total games 87–80–2 .521%. 109 Big Ten Conference games 41–66–2 .385%

With the Gophers' move to TCF Bank Stadium, only one NCAA Division I FBS football program now plays in a domed stadium. Syracuse has its own such facility on campus. When the Gophers first moved to the Metrodome, the NFL-class facilities were seen as an improvement over the aging Memorial Stadium. Initially, attendance increased.[78] However, fans waxed nostalgic over fall days playing outdoors on campus.[79] TCF Bank Stadium now provides an outdoor, on-campus venue for the team.

In the 2010 season, the University of Minnesota Golden Gopher Baseball team played all of their home games at the Metrodome (except a game at the new Target Field on March 27, 2010).[80] The University of Minnesota Golden Gophers baseball team had played games at the Metrodome during February and March since 1985 because of weather. Later games were played at Siebert Field, except for 2006 when all but two home games were played at the Metrodome. The team often played major tournaments at the Dome, which included the Dairy Queen Classic, where three other major Division I baseball teams play in an invitational. Before the NCAA's 2008 rule in Division I regarding the start of the college baseball season, the Golden Gophers would often play home games at the Metrodome earlier than other teams in the area to neutralize the advantage of warmer-weather schools starting their seasons earlier in the year. Some early Big Ten conference games were played at the Metrodome, and the Golden Gophers enjoyed home-field advantage during the early part of the season before the weather warmed, and the Gophers could play games on-campus. Other small colleges also played games in the stadium during the weeks before the Metrodome was open for Division I play. In 2010, 420 amateur baseball and softball games—including the majority of the Golden Gophers' home schedule—were played at the Metrodome.[81]

The size of Siebert Field also affected the Golden Gophers starting in 2010. The Golden Gophers last hosted an NCAA baseball tournament regional in 2000, with temporary seating added. With the Metrodome being available for the tournament starting in 2010, the team could easily place a bid for, and have a better possibility of hosting, an NCAA baseball regional or super regional.

Other cold-weather teams have played at the Metrodome. Big 12 Conference member Kansas has played two series (2007 and 2010) at the Metrodome because of inclement weather against South Dakota State University and Eastern Michigan, respectively.[82]

The Minnesota Kicks were supposed to move into the Metrodome for the 1982 NASL season. However, the franchise folded in November 1981. The Minnesota Strikers played the 1984 NASL season at the Dome. 52,621 saw the Minnesota Strikers defeat Tampa Bay 1–0 on May 28, 1984. MSHSL boys and girls soccer championships were also held at the stadium. The Minnesota Thunder played selected games at the Dome from 1990 to 2009. Minnesota Stars FC, later renamed to Minnesota United FC, opened their 2012 season at the stadium and used it for the 2013 NASL spring season. The field dimensions for soccer at the Metrodome were 110 by 70 yards (101 m × 64 m). The largest crowd to see a soccer game in Minnesota was at the Metrodome.

The concert capacity of the Metrodome was around 60,000 people, depending on seating and stage configurations, which made it a profitable location for stadium tours during the late 80s and 90s. By comparison, the Target Center in Minneapolis has a concert capacity of up to 20,500. Acoustics at the Metrodome for these concerts were "iffy at best".[83]

The Metrodome was constructed in an area of downtown Minneapolis known as "Industry Square".[88] Development in the Downtown East neighborhood around Metrodome took many years to materialize. For many years, there were few bars or restaurants nearby where fans could gather, and tailgating was expressly forbidden in most parking areas. The City of Minneapolis was directing the development of the entertainment districts along with Seven Corners in Cedar-Riverside, Hennepin Avenue, and the Warehouse district. The Metrodome existed among several parking areas built upon old rail yards, along with defunct factories and warehouses. The Star Tribune owns several blocks nearby that have remained parking lots. The Metrodome was not connected to the Minneapolis Skyway System, although that had been proposed in 1989 to be completed in time to host Super Bowl XXVI. The Star Tribune properties and the Minneapolis Armory had not been developed and stood between the Metrodome and the rest of Downtown Minneapolis. Only in recent years did redevelopment begin moving Southeast to reach the Metrodome. More restaurants, hotels, and condominiums have been built nearby. The METRO Blue Line light rail connected the Minneapolis entertainment district with the Metrodome and the Airport.

The Metrodome was not a true multi-purpose stadium. Rather, it was built as a football stadium that could convert into a baseball stadium. The seating configuration was almost rectangular in shape, with the baseball field tucked into one corner.[89] The seats along the four straight sides directly faced their corresponding seats on the opposite side, while the seats in the corners were four quarter-circles.

While this was more than suitable for the Vikings and Gophers, with few exceptions this resulted in poor sightlines for baseball. For instance, the seats directly along the left-field line faced the center field and right field fences. Unlike other major league parks, there were no seats down to field level.[24] Only 8,000 seats were located in the lower deck between home plate and the dugouts, where most game action occurs.[89] Seats in these areas were popularly known as "the baseball section." However, even the closest front-row seats were at least 5 or 6 feet (1.5 or 1.8 m) above the field.

The way that many seats were situated forced some fans to crane their necks to see the area between the pitcher's mound and home plate. Some fans near the foul poles had to turn more than 80°, compared to less than 70° with the original Yankee Stadium or 75° at Camden Yards. For that reason, the seats down the left-field line were typically among the last ones sold; the (less expensive) outfield lower deck seating tended to fill up sooner. Nearly 1,400 seats were at least partially obstructed – some of them due to the right-field upper deck being directly above (and somewhat overhanging) the folded-up football seats behind right field; and some of them due to steel beams in the back rows of the upper deck which are part of the dome's support system.

On the plus side, there was relatively little foul territory, which was not typical of most domed stadiums (especially those primarily built for football). Also, with the infield tucked into one corner of the stadium, the seats in the so-called "baseball section" had some of the closest views in Major League Baseball. In 2007, the Twins began selling seats in extra rows behind the plate which were previously only used for football. The sight lines were also very good in the right field corner, which faced the infield and was closer to the action than the left field corner.

Unlike most domed stadiums, the Metrodome's baseball configuration had asymmetrical outfield dimensions.[90]

The Twins stopped selling most of the seats in sections 203–212 of the upper level in 1996. This area was usually curtained off during the regular season. However, the stadium could easily be expanded to full capacity for the postseason, or when popular opponents came to town during the regular season.

As part of the deal with Metrodome, the Minnesota Twins had post-season priority over the Gophers in scheduling. If the Twins were in the playoffs with a home series, the baseball game took priority and the Gopher football game had to be moved to a time suitable to allow the grounds crew to convert the playing field and the stands to the football configuration.

The last month of Major League Baseball's regular season often included one or two Saturdays in which the Twins and Gophers used Metrodome on the same day. On those occasions, the Twins game would start at about 11 am local time (TV announcer Dick Bremer sometimes joked that the broadcast was competing with SpongeBob SquarePants). Afterward, the conversion took place and the Gophers football game started at about 6 pm. The University of Minnesota was the only school in the Big Ten that shared a football facility with professional sports teams for an extended period of years.

In 2007, there were two such schedule conflicts, on September 1 and 22. In 2008, there were no conflicts on the regular-season schedule.

Due to the minimum time needed to convert the field, a baseball game that ran long in clock time had to be suspended, and concluded the next day. The only time this happened was on October 2, 2004, when a game between the Twins and Indians reached the end of the 11th inning after 2:30 pm in a tie and resumed the next day.[91][92][93][94]

The Vikings had rights to the Dome over the Twins except for World Series games. In 1987, the Vikings' home date with the Tampa Bay Buccaneers scheduled for the same day as Game 2 of the World Series was moved to Tampa, and the Vikings' game with the Denver Broncos scheduled for the same day as Game 7 was pushed back to the following Monday night.

The Twins' 2009 AL Central division tiebreaker with the Detroit Tigers was played on Tuesday, October 6, 2009. One-game playoffs are normally held the day after the regular season ends (in this case, the season ended on Sunday, October 4), but the Vikings were using Metrodome for Monday Night Football on October 5. The Twins were awarded the right to host the tiebreaker because they won the season series against Detroit.

The Metrodome will also be remembered in NFL history as the site of four of the longest NFL touchdowns in history in terms of yardage. From scrimmage, only 15 plays have ever gone the maximum 99 yards for a touchdown in league history. One of the two runs on that list is by Dallas Cowboys running back Tony Dorsett against the Vikings on January 3, 1983, during a Monday Night Football game. One of the 13 such pass plays is Vikings quarterback Gus Frerotte's connection with receiver Bernard Berrian during a game against the Chicago Bears on November 30, 2008.

Because returns can go longer than 99 yards, the Metrodome had also seen the record set for longest return at the maximum possible total of 109 yards. On November 4, 2007, the San Diego Chargers' Antonio Cromartie returned a missed Vikings field goal for a touchdown, a mark that stood unequaled until October 27, 2013, when Minnesota's Cordarrelle Patterson returned the Green Bay Packers' opening kickoff of Sunday Night Football, the maximum distance.

MoA signage at the Metrodome

In 2009, Mall of America purchased naming rights for the field at Metrodome. The contract stated that the field would be called "Mall of America Field at Hubert H. Humphrey Metrodome" for a three-year period, beginning October 5, 2009, and ending February 28, 2012.[95] The name was still used for the 2012 and 2013 seasons.

Despite possible inference from the signage, the MoA name applied only to the field, not the stadium as a whole. The building remained Hubert H. Humphrey Metrodome. The connection between Mall of America and the Metrodome is also notable because Mall of America is built on the site of the former Metropolitan Stadium. The mall and the dome were located about 10 miles (16 km) apart from each other.

From the tops of the outfield fences upwards, the baseball foul poles in the Metrodome were unique, in that they were not "poles" at all. Instead, they consisted of a fabric-like material. In left field, the "pole" hung from the roof, down to the top of the left field fence. In right field, the "pole" hung from the bottom of the upper deck to the top of the right field fence. Because the upper deck in right field overhung the playing field slightly, this resulted in the foul pole not being vertical, actually leaning inward slightly toward home plate.[96]

The Twins moved to their new ballpark, Target Field, in 2010,[99] after attaining their new stadium with an effort that began in the mid-1990s. Although indoor baseball had critics when Metrodome opened, it was positively regarded by players and fans.[100] By 2001, with Metrodome's peculiarities revealed, and several newer purpose-built Major League Baseball stadiums constructed, an ESPN Page 2 reader poll ranked it as one of the worst Major League Baseball stadiums.[73] Twins management claimed Metrodome generated too little revenue for the Twins to be competitive; specifically, they received no revenue from luxury suite leasing (as those were owned by the Vikings) and only a small percentage of concessions sales. This came to a head in 2001, when the Twins were nearly contracted along with the Montreal Expos, who were also generating insufficient revenue and had a stadium in poor condition.[101] Also, the percentage of season-ticket-quality seats was said to be very low compared to other stadiums. From 2003 through 2009, the Twins had year-to-year leases, and could have moved to another city at any time. However, with no large American markets or new major-league-quality stadiums existing without a current team, it was accepted that the Twins could not profit from a move. The Twins sought a taxpayer subsidy of more than $200 million to assist in construction of the stadium. On January 9, 2005, the Twins went to court to argue that their Metrodome lease should be considered "dead" after the 2005 season. In February, the district court ruled that the Twins' lease was year-to-year and the team could vacate Metrodome at the end of the 2005 season.

In late April 2007, Hennepin County officially took over the future ballpark site (through a form of eminent domain called "quick-take") which had been an ongoing struggle between the county and the land owners. On October 15, 2007, the two sides reached a negotiated settlement of just under $29 million, ending the dispute. As a result, the county noted it would have to cut back on some improvements to the surrounding streetscapes, though it also revealed that the Pohlad family had committed another $15 million for infrastructure.[102]

The Minnesota Golden Gophers football program began playing in Metrodome for the 1982 season. Attendance was expected to increase over the old Memorial Stadium attendance, especially for late fall games, due to the climate controlled comfort. Initially, average attendance had increased over previous seasons at Memorial Stadium.[78] But, the venue was removed from the traditional on-campus football atmosphere if fans wanted to attend a Gophers football game. Students had to take a bus from the campus to the stadium. The distance from the main campus, along with poor performance by the Gopher football team, caused interest to wane.[103]

The Gophers officially moved back onto campus, to TCF Bank Stadium, for the 2009 football season. The university believed an on-campus stadium would motivate its student base for increased ticket sales, and also would benefit from athletic revenues, not only for the football program, but the non-revenue sports as well. The new stadium reportedly cost less than half of a current-era NFL-style football stadium, and was built on what were former surface parking lots just a few blocks east of the former Memorial Stadium, with the naming rights purchased by TCF Financial Corporation. The University of Minnesota expected to raise more than half the cost of the stadium via private donations. The Gopher Stadium bill was passed by both houses on May 20, 2006, the day before the Twins Stadium bill passed. On May 24, 2006, Governor Pawlenty signed the Gopher bill on the university campus.

The Vikings initially supported a Superfund site in Arden Hills, but costs of developing infrastructure made the site unworkable.[104] A number of sites in Minneapolis were floated before the team and state settled on a location adjacent to and including the current Metrodome site.[105]

On May 10, 2012, the Minnesota Legislature approved funding for a new Vikings stadium on that site. The project had a budget of $1.027 billion, of which the Vikings covered $529 million, the state covered $348 million, and the remaining $150 million was covered by a Minneapolis hospitality tax.[106] The bill was signed by Governor Dayton on May 14. The Vikings played in the Metrodome until the end of the 2013 season.[4] The Vikings' temporary home during construction was TCF Bank Stadium.[107][108]
