U.S. Route 34

In the state of Colorado, U.S. Route 34 runs north from Granby through Rocky Mountain National Park. It passes through Estes Park, Loveland, and Greeley before entering Nebraska east of Wray.

Within Rocky Mountain National Park US 34 is known as Trail Ridge Road. Due to its high elevation through the park and over the Continental Divide, Route 34 closes entirely in winter from the Colorado River Trailhead on the west (10 miles north of the Grand Lake entrance) to Many Parks Curve on the east (8 miles from the Estes Park entrance.) Closure runs roughly from mid-October to Memorial Day weekend in May, and can occur at any time in summer due to high alpine snow storms.[1]

Route 34 transverses Fall River Pass and Milner Pass in the Front Range of Colorado.

In the state of Nebraska, U.S. Route 34 is a major east–west arterial surface road along the southern portion of Nebraska. It enters Nebraska west of Haigler and overlaps other routes for the majority of its routing. U.S. 34 passes through Hastings, Grand Island, Seward, and Lincoln before entering Iowa between Plattsmouth and Bellevue.

U.S. Route 34 from between Hastings and Grand Island is known as the Tom Osborne Expressway, which is named for the former Hastings resident, Nebraska Cornhuskers football coach, and Congressman. In Lincoln, U.S. 34 overlaps with Interstate 180 from its junction with Interstate 80 into downtown where it becomes North 9th/North 10th Streets, then east as "O" Street. Also, the segment from the Lancaster County/Cass County border to Nebraska Highway 1 south of Elmwood is the Bess Streeter Aldrich Memorial Highway, after the former author and Elmwood resident.

In the state of Iowa, U.S. Route 34 is a major east–west arterial surface road across southern Iowa. It enters Iowa west of Glenwood and then passes through Glenwood, Red Oak, Corning, and Creston before intersecting Interstate 35 at Osceola. East of Osceola, it continues through Chariton and Georgetown then onto Albia before meeting U.S. Route 63 at a traffic circle in Ottumwa.

East of Ottumwa to Burlington, the highway overlaps Iowa Highway 163. This segment of highway is an expressway with some freeway segments. As of November 12, 2008, it bypasses Fairfield and then bypasses Mt. Pleasant, with a portion of this also concurrent with US-218 and Iowa 27, which is also the Iowa route for the Avenue of the Saints. It then continues southeast towards Burlington bypassing New London and then Danville and Middletown. The freeway segment through Burlington was completed in the 1970s. It then crosses the Mississippi River on the Great River Bridge into Illinois which was completed in the early 1990s. In 2015, a 15-mile segment of U.S. Route 34 in Montgomery and Adams counties won the Sheldon G. Hayes Award for the highest quality asphalt pavement in the nation.[2]

Much of this route was originally known as the Bluegrass Highway and parallels tracks of what was originally the Burlington and Missouri River Railroad and is now the BNSF. Amtrak's California Zephyr passenger rail service also parallels this route.

U.S. 34 in the state of Iowa is officially designated the Red Bull Highway in honor of the 34th Infantry (Red Bull) Division.
