U.S. Route 36 is a major east–west route in the U.S. state of Colorado, extending from Rocky Mountain National Park to the Kansas state line.

Route description

US 36 meets SH 7 at the small town of Lyons, Colorado, on the eastern edge of the Rocky Mountains.

US Route 36 begins at Deer Ridge Junction in Rocky Mountain National Park, where it intersects US Route 34 (Trail Ridge Road) on the eastern slope of the Rocky Mountains. It exits the park at the Beaver Meadows Visitor Center and enters the town of Estes Park, where it is briefly overlapped with Business US 34 until it meets (but does not cross) the main US 34 again at an intersection shaped like the letter K. On its way out of Estes Park it intersects SH 7 at South St. Vrain Avenue, for the first of three times.

It then descends southeast through North St. Vrain Canyon to the town of Lyons, which it enters on Main Street. At 5th Avenue in Lyons, it intersects SH 7 again, beginning an overlap to Boulder which is signed only as US 36. At 5th Avenue and Main Street in Lyons, it divides into a pair of one way streets with the eastbound direction traveling one block south on 5th Avenue and turning east onto Broadway Street, and the westbound direction using Main Street. The two directions reunite in two blocks and leave Lyons southeastward as four-lane Ute Highway. Just outside of Lyons, US 36 turns south at a signalized intersection onto two-lane North Foothills Highway, while SH 66 continues east to Longmont. From Lyons to Boulder, US 36 pretty much traces the edge of the foothills.

US 36 enters Boulder on four-lane-wide 28th Street, where it serves the city's main shopping area. On the north side of Boulder, it intersects SH 119 at Diagonal Highway, beginning a 1.4 mile overlap that extends until SH 119 turns west onto Canyon Boulevard towards Nederland. One block farther south, SH 7 diverges from its overlap with US 36 by turning east onto Arapahoe Avenue. Leaving the Boulder shopping district, US 36 passes through the University of Colorado campus area as an expressway, and at a diamond interchange with Baseline Road, it meets Spur US 36, a two-block long connector to SH 93, signed only as "To SH 93" and "To US 36".

Just after the Baseline Road interchange, US 36 curves to the southeast and becomes the Denver-Boulder Turnpike, intersecting SH 157 Foothills Parkway on its way out of town. Northwestbound traffic approaching Boulder on the turnpike can stop at a scenic overlook on a high hill, providing a panoramic view of the Front Range mountains and the City of Boulder; a monument to the Denver-Boulder Turnpike's original builders is also located here. Continuing southeast, the road enters the fast growing Denver suburbs of Westminster and Broomfield, which have become popular locations for High-Tech businesses, which can be seen lining the turnpike. An interchange at 96th Street provides access to the Northwest Parkway and E 470 outer beltway around Denver. At an interchange with SH 121 and SH 128 in Broomfield, it meets (but does not cross) US Route 287. It then intersects US 287 again at Federal Boulevard.

At the very complicated junction of US-36, I-25, I-76, and I-270, the Turnpike ends and US-36 emerges overlapped and unsigned with I-270, and continues overlapped and unsigned with I-70 when I-270 ends near the former Stapleton Airport site. At Colfax Avenue, this I-70/US 36 overlap is also joined by US-287 (again) and US-40.

From Watkins to Byers, US-36 continues unsigned in its four-way multiplex with I-70, US-40, and US-287, while its former route through Bennett, Strasburg, and Byers is signed separately as Colorado State Highway 36.

At Byers, US 36 heads eastward on its own as a separate rural highway, while the I-70/US-40/US-287 multiplex curves to the southeast. It passes through several small towns such as Last Chance, Lindon, Anton, and Cope in Washington County and Joes and Idalia in Yuma County. At Cope, it is joined by SH 59 for about 6 miles. In Yuma County, near Idalia, it jogs north, becoming concurrent with US 385 for about 3 miles before turning east again and continuing about 10 miles to the Kansas border.^[2]

Toll Road

The portion of US Route 36 within Rocky Mountain National Park is a toll road, requiring a park entrance fee.

History
