North Central Freeway (Washington, D.C.)

In 1959, the Mass Transportation Plan outlined a North Central Freeway routing that would parallel Georgia Avenue through northern D.C. However, no detailed studies into the feasibility or impact of this route were undertaken at the time. A later study conducted in 1964 included diagrams of the 1959 route, but with the roadway in a 4-2-4 configuration instead of a 3-3 configuration. [2]

In November 1962, the Kennedy administration released a document "Recommendations for Transportation in the National Capital Region; A Report to the President for transmittal to Congress by the National Capital Transportation Agency".

It replaced the 1959 concept of 3 separate northern radial mixed traffic highways with that of a 2 into 1 "Y" route for a North Central Freeway as inside-the-Beltway I-70S, joined by an I-95 North East Freeway near Fort Totten, and continue together as the I-95 North Central Freeway.

The I-70S and I-95 portions of the North Central would be routed along the existing B&O Metropolitan Branch RR (today's WMATA Red Line). Accordingly, this avoids "the substantial relocation of persons, loss of taxable property and disruption of neighborhoods that would result from construction of the Northeast, North Central and Northwest Freeways proposed in the 1959 plan. Further savings are realized by placing the rapid transit lines to Silver Spring and Queen's Chapel in this same railroad corridor."

This B&O "Y" route concept North Central Freeway was later politically undermined by planning that failed to follow it. [3]

In a series of proposals published in 1963 and 1964, the subsequent study of the North Central Freeway and Northeast Freeway indirectly ignored earlier suggestions regarding the use of the B&O railroad corridor; instead, no fewer than 17 separate alignments were proposed for the NCF south of the Northeast Freeway, and a staggering 35 were proposed for the NCF (I-70S) north of it, many of which did not make much use of the railroad alignment.

One important aspect of the study was the consideration of consolidating the North Central Freeway (I-70S) and Northeast Freeway (I-95) into a single freeway that would run south to the Inner Loop (designated solely as I-95). Many different alignments, including ones paralleling Georgia Avenue and Sherman Avenue through northern D.C., were considered as part of a consolidated routing of the North Central Freeway south of the Northeast Freeway. [4]

The study as a whole generally rejected alignments paralleling Georgia Avenue in favor of alignments along the B&O railroad, primarily due to the residential nature of the former and the disruption that the route would engender if sent through it. However, it did not reject out-of-hand the concept of separate routings for the North Central Freeway and the Northeast Freeway due to concerns that the former would not be able to handle the traffic levels of both routes combined. Twelve of the alternate routes considered by the study had this separated route approach, with the North Central Freeway routed via Georgia Avenue and Sherman Avenue; the other 5 advocated the consolidated alignment. Many of the alignments proposed for the North Central Freeway north of I-95 would have resulted in wholesale neighborhood demolition, with hundreds of homes completely removed to make space for the freeway and the expansive interchanges planned for it. [4]

The study itself recommended the construction of a consolidated alignment, with the North Central Freeway following the B&O all the way through the District and outside it, within the Capital Beltway, before turning to follow 16th St. to the Beltway, which it would meet, and continue north of, near Sligo Park. Surprisingly, the study stated that the North Central Freeway north of the Beltway would not carry an Interstate designation throughout. [4]

The enormous opposition to the 1964 and 1965 alignments for the North Central Freeway led to a supplementary study being conducted in 1966 that more closely examined routings that paralleled the existing B&O railroad corridor. Most of the alternatives created during this study retained a six-lane configuration for the northern I-70S segment and an eight-lane configuration for the southern I-95 segment. Three major options were considered:

• a high-level option, with the freeway elevated over the railroad, allowing most of the industrial properties to remain in situ
• a low-level option, with the freeway directly adjacent to the railroad or slightly below it
• a below-grade option, with the railroad and Metro facilities suspended over the freeway
• a concealed-railroad option, with the railroad and Metro buried beneath the freeway alignment

The option chosen was the low-level option. Tunnels would be constructed in the vicinity of Montgomery College, and the freeway would be depressed in the Brookland area. However, in the Takoma Park, Washington, D.C. the freeway would be slightly elevated, yet the crossing of Georgia Avenue would be depressed instead of elevated in the 1964 proposal. [5]

The low-level option relocated the I-70S/I-495 wye interchange to a point 3/4 mile west of Georgia Avenue (MD 97), with the western wye of the interchange closely hugging the railroad alignment on its western edge; various short tunnels would be constructed to carry the freeway across parking lots and under the railroad, where it would join the eastern leg of the wye and continue south as a six-lane freeway. One major characteristic of this alignment, as compared to previous alignments, is its close companionship with the railroad; the separate carriageways would cross under/over it repeatedly to avoid housing developments and other areas; in Takoma Park, the railroad would be flanked by I-70S's carriageways, while south of Van Burean Street the southbound carriageway would shift to the northern side of the railroad and meet the Northeast Freeway near Riggs Road and New Hampshire Avenue. [5]

The 1966 plan included separate ramp connections to and from both freeways and North Capitol Street, but deleted 'round-the-corner' connections to and from southbound I-70S and northbound I-95. South of the Northeast Freeway, the North Central Freeway would run to the east of the railroad, after passing through a 950-foot (290 m) tunnel in the Brookland area. At the point where the railroad curves to the southwest, the freeway would continue south and enter the site of the Union Station interchange, sparing 3 blocks near Jackson St. NE but removing 69 homes in the freeway's path. Also, the 196 plans for the North Central Freeway removed the reversible roadway that had been previously considered. [5]

The final length of the NCF would have been 7.71 miles (12.41 km), cost approximately $193 million to build, and would have displaced 535 homes and 159 businesses. Ultimately, the plan was doomed by further opposition as a direct result of indecisiveness on the part of D.C. and Maryland transportation officials. [5]

In 1968, the U.S. National Capital Planning Commission released an updated Major Transportation Plan for the D.C. area which deleted the North Central Freeway and Northeast Freeway from the city's freeway grid. Traffic that would have made use of these freeway corridors was expected to either use the local street grid or the Capital Beltway. I-70S would have terminated on the Capital Beltway (as I-270 does now), and I-95 would have followed New York Avenue to the Baltimore-Washington Parkway, then continued north to its original routing, possibly via the Capital Beltway. [6]

The justification used for this deletion, as recorded in the NCPC's "Red Book", was that traffic with destinations beyond the District should not be permitted to travel through the District, but instead bypass it via the Beltway. Traffic with destinations within the District, as noted above, were expected to use the street grid; the NCPC further justified this by stating that the Interstate Highway System as defined did not guarantee direct inner-city access. Furthermore, the NCPC also baldly stated that the construction of the North Central Freeway would simply provide another way into the District for commuters, which was seen as undesirable and unnecessary. [6]

In 1971, a study released by DeLeuw retained the I-70S/I-95 North Central Freeway configuration. The study's various alternatives differed little from one another; one major similarity was the I-70S/I-95 wye junction, with the six-lane I-70S and the eight-lane I-95 (narrowing to six lanes, with the remaining two forming off ramps to North Capitol St.) merging into a 12-lane freeway that would quickly narrow to 10 lanes within the Union Station interchange. The plans included the 3/4-mile Rhode Island Ave.-Michigan Ave. tunnel, as well as revisions to an earlier 1970 proposal that would reduce the number of homes required to be removed from 69 to 34. [7]
