U.S. Highway 36 begins at Deer Ridge Junction in Rocky Mountain National Park, where it intersects U.S. Highway 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 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 crosses Boulder Creek and passes through the University of Colorado campus area as an expressway to the interchange with Baseline Road, where it meets Spur US 36, a two-block long connector along 27th Way to SH 93, signed only as "To SH 93" and "To US 36".

Boulder to Denver

Just after the Baseline Road interchange, US 36 changes to a southeasterly direction, using the route of the original Denver-Boulder Turnpike, a toll road from its opening in 1952 until 1967. [2] [3] The road intersects SH 157 Foothills Parkway on its way out of Boulder. Northwestbound traffic approaching Boulder on the turnpike can stop at the Davidson Mesa Overlook, providing a panoramic view of the Front Range mountains, the City of Boulder, and its famous Flatirons rock formation; a monument to the Denver-Boulder Turnpike's original builders is also located here. [4] Continuing southeast, the road enters the fast-growing Denver suburbs of Broomfield and Westminster, 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 thereby to the E 470 outer beltway around Denver. At an interchange with SH 121 and SH 128 in Broomfield, it meets (but does not cross) U.S. Highway 287. It then has another interchange with US 287 again at Federal Boulevard near 76th Avenue in Westminster. The interchange at 76th and Federal was the terminus of the original Denver-Boulder Turnpike when it was still a toll road, but in common parlance the Turnpike now extends all the way east to I-25.

The US 36 bikeway, part of the multi-modal Fastracks US 36 Express Lanes Project, mostly parallels the road between Table Mesa Drive in Boulder and 80th Avenue in Westminster, the first 11-mile stretch between Westminster and Louisville/Superior opening on Bike-to-Work Day in June 2015, [5] the full route to Table Mesa in Boulder in March 2016. [6] [7]

Denver to Byers (unsigned)

At the very complicated junction of US 36, I-25, I-76, and I-270, 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 (the third time the two highways come into proximity) and US 40. From the interchange with Colfax Avenue, the road continues to Watkins and then to Byers, unsigned in its four-way overlap with I-70, US 40, and US 287.

Byers to Kansas state line

At Byers, US 36 heads eastward on its own as a separate rural highway, while the I-70/US 40/US 287 overlap curves to the southeast. US 36 passes through several very small settlements including Last Chance, Lindon, Anton, and Cope in Washington County and Joes and Idalia in Yuma County. Many of the towns on this desolate 105-mile (169 km) section of highway are so small they do not provide basic traveler services such as gasoline, and winter drivers are cautioned by signs that there is no snowplowing at night. At Cope, it is joined by SH 59 for about 6 miles (9.7 km). In Yuma County, near Idalia, it jogs north, becoming concurrent with US 385 for about 3 miles (4.8 km) before turning east again and continuing about 10 miles (16 km) to the Kansas border. [1]


Denver-Boulder Turnpike

The Denver-Boulder Turnpike was championed by business and university interests in Boulder due to there being no direct route between Denver and Boulder. [8] The 17.3-mile (27.8 km) toll road stretched from Federal Boulevard (US 287) in Westminster to Baseline Road in Boulder, and opened on January 19, 1952 with a toll of $0.25. The Valley Highway from downtown Denver opened in 1952–1954, feeding directly into the Turnpike. Most of the new highway carried SH 185 (US 87), but traffic continuing north on that route initially had to exit at 70th Avenue, now SH 224, with the remainder of the route to Federal Boulevard becoming a realignment of SH 382. When the bonds for the Turnpike were paid off ahead of time in 1967, tolls were removed. [9]

Express lanes

Beginning in July 2012, the Colorado Department of Transportation built a high-occupancy toll lane (HOT lane) in each direction between Federal Boulevard and 88th Street in Louisville, Colorado. [10] Phase 1 of the project, costing $497 million, will open in summer 2015. High-occupancy vehicles and buses like RTD's Flatiron Flyer travel free in the HOT lanes, while single-occupancy vehicles must pay between $1.25 to $7.60, depending on time of day, or up to $13.68 without an electronic toll collection pass. [11] To accommodate the lanes, several bridges were replaced and shoulders were widened along the highway. Phase 2 of the project, anticipated to be complete by early 2016, will extend the HOT lanes from 88th Street to Table Mesa Drive in Boulder, Colorado, through a public–private partnership. [12]

The road from Strasburg east to the Kansas state line was added to the state highway system in 1922 as the Colorado part of a proposed "Kansas City-Denver Airline Highway" that would have cut 72 miles (116 km) from the existing highways between Denver and Kansas City. The planned route followed present U.S. Route 36 in Kansas to Mankato, but then turned southeasterly via Concordia and Clay Center to Manhattan, where it met the Victory Highway (now US 24 and US 40). [13] The new state highway was assigned the Primary Road No. 102 designation, and kept its number when many others were changed in 1923. [14] [15]

The west end of State Highway 102 was initially at Strasburg, [16] but by 1924 it had been shifted to Byers, using the present County Roads 10 and 197 to return to current US 36. In 1927–1929 the entire SH 102 became part of US 36, which was realigned to go west rather than southwest from Norton, Kansas. The west end was moved back to Strasburg in 1932–1934, and a number of right-angle turns were eliminated by constructing diagonal cutoffs west of Cope and at the state line in 1934–1935. US 36 was extended west in 1936–1937 as an overlap with US 40 on Colfax Avenue to downtown Denver, where it would end for the next 30 years. Paving began in 1937–1939 and was completed in 1947–1949, including a realignment off County Roads DD and 12 north of Idalia. The junction with US 40 near Strasburg-Byers was changed again in 1954–1955, now following County Road 181 east of Byers. [17] Finally in 1958–1959 a realignment west of Idalia eliminated four more 90-degree turns. [15]

When the tolls were removed from the Denver-Boulder Turnpike, the road became State Highway 49, which also replaced all of SH 382. US 36 was also extended at this time, following the Valley Highway (by then part of I-25) from Colfax Avenue north to SH 49, and then overlapping SH 49 to the end at Baseline Road, SH 119 on 28th Street, SH 7 to Lyons, and SH 66 to end at US 34 in Estes Park. Late in 1968 these redundant state highway designations were dropped, [14] resulting in the elimination of SH 49 and SH 102, realignment of SH 119 to go more directly in Boulder, and creation of gaps on SH 7 and SH 66. [15] In 2012, the turnpike was also given the honorary name Buffalo Highway in recognition of the University of Colorado's mascot, [18] though this name has not achieved common use.

Returning to Colfax Avenue east of Denver, the first part of I-70 in that area opened in 1961–1962, bypassing Watkins and Bennett and carrying US 36 (and US 40/287). The freeway was extended east past Strasburg and Byers in 1963–1964, including the final realignment of US 36 northeast of Byers. The old alignment was initially removed from the state highway system, but in 1964–1965 it returned as part of SH 8. When this route was largely eliminated in late 1968, this bypassed highway instead became State Highway 36 (and SH 40 east of Byers), with US 36 remaining on I-70. US 36 was realigned through Denver in 1970, following I-70 and I-270 north of downtown. (Note that, until 2000, I-270 ended at I-76, and US 36 traffic had to use short pieces of I-76 and I-25.) A final westerly extension came in 1977–1978, when US 36 replaced the western segment of SH 66 (except for a spur) from Estes Park into Rocky Mountain National Park and another junction with US 34. [15]

In early September 2013, a 31-mile (50 km) section of US 36 from Estes Park to Boulder was closed due to damage from the 2013 Colorado floods. For a time, the only route available in and out of Estes Park was a long detour through Nederland, Blackhawk, and Golden. The section in North St. Vrain Canyon west of Lyons was especially heavily damaged. [19] The road was finally reopened two months later with the help of the National Guard. [20] Permanent repairs were started in January, 2014. [21]

In July 2019, cracks appeared on the eastbound lanes of the highway in Westminster due to shifting soil underneath. The highway has been closed as construction crews try to address the problem. [22]

State Highway 36
Location Aurora to Byers, Colorado

SH 36 is the stretch of former US 36 that runs from Aurora to Byers. Its western terminus is at exit 292 of I-70. Form there, it goes east through Watkins, Bennett, and Strasburg, meeting I-70 twice along the way before meeting I-70 for a third time at its eastern terminus (exit 316). This first junction with I-70 east of Aurora is in Bennett, at exit 306. The second such junction is at an underpass near Strasburg, with no access to or from the Interstate.

The highway was originally signed as part of SH 8.

Interstate 70 (I-70) is a major east–west Interstate Highway in the United States that runs from I-15 near Cove Fort, Utah, to a Park and Ride lot just east of I-695 in Baltimore, Maryland. I-70 approximately traces the path of U.S. Route 40 east of the Rocky Mountains. West of the Rockies, the route of I-70 was derived from multiple sources. The Interstate runs through or near many major cities, including Denver, Topeka, Kansas City, St. Louis, Indianapolis, Columbus, Pittsburgh, and Baltimore. The sections of the interstate in Missouri and Kansas have laid claim to be the first interstate in the United States. The Federal Highway Administration has claimed the section of I-70 through Glenwood Canyon, Colorado, completed in 1992, to be the last piece of the Interstate Highway system, as originally planned, to open to traffic. The construction of I-70 in Colorado and Utah is considered an engineering marvel, as the route passes through the Eisenhower Tunnel, Glenwood Canyon, and the San Rafael Swell. The Eisenhower Tunnel is the highest point along the Interstate Highway system, with an elevation of 11,158 ft (3,401 m).

U.S. Route 287 U.S. Highway in the United States

U.S. Route 287 (US 287) is a north–south United States highway. At 1,791 miles (2,882 km) long, it is the longest three-digit U.S. route. It serves as the major truck route between Fort Worth and Amarillo, Texas, and between Fort Collins, Colorado, and Laramie, Wyoming. The highway is broken into two segments by Yellowstone National Park, where an unnumbered park road serves as a connector.

U.S. Route 36 Highway in the United States

U.S. Route 36 (US 36) is an east–west United States highway that travels approximately 1,414 miles (2,276 km) from Rocky Mountain National Park, Colorado to Uhrichsville, Ohio. The highway's western terminus is at Deer Ridge Junction, an intersection in Rocky Mountain National Park, Colorado, where it meets US 34. Its eastern terminus is at US 250 in Uhrichsville, Ohio.

Interstate 76 (I-76) is an Interstate Highway in the Western United States that runs from Interstate 70 in Arvada, Colorado to an intersection with Interstate 80 near Big Springs, Nebraska. All but three miles of the highway's route is in Colorado.

Interstate 225 (I-225) is a connector spur route of Interstate 25 in Colorado. It is the only auxiliary route of Interstate 25, and one of two auxiliary Interstate highways in the state of Colorado. I-225 traverses Aurora and small portions of Denver and Greenwood Village. It runs north from Interstate 25 to Interstate 70. It intersects with Interstate 70 Business/U.S. Highway 40/U.S. Highway 287, known locally as Colfax Avenue. Construction on the freeway began in 1964 and continued progressively through many years until final completion in 1976.

Colorado State Highway 7

State Highway 7 is an 81.64 miles (131.39 km) long state highway in the U.S. state of Colorado. It is located in the north-central portion of the state, traversing the mountains on the east of the continental divide south of Estes Park as well as portions of the Colorado Piedmont north of Denver. The northwestern segment of the highway is part of the Peak-to-Peak Scenic Byway and furnishes an access route to Estes Park, Colorado and Rocky Mountain National Park. In its southeast portion it skirts the northern end of the Denver Metropolitan Area, providing an access route connecting Boulder, Lafayette and Brighton with Interstate 25 and Interstate 76.

Northwest Parkway

The Northwest Parkway is a 9-mile (14 km) road running from the intersection of I-25 and E-470 to US 36. Both termini are in Broomfield, Colorado, northwest of Denver. In combination with E-470 and SH 470, the Northwest Parkway forms a partial beltway of approximately 83 miles (134 km) around the Denver-Aurora Metropolitan Area. Some 18 miles (29 km) lie between the west end of the Northwest Parkway and the northwest end of SH 470, the opposite end of the beltway.

State Highway 470 is the southwestern portion of the Denver Metro area's beltway. Originally planned as Interstate 470 in the 1960s, the beltway project was attacked on environmental impact grounds and the interstate beltway was never built. The portion of "Interstate 470" that was built as a state highway is the present-day SH 470, which is a freeway for its entire length. The route has previously been called the Centennial Freeway.

Colorado State Highway 95

State Highway 95 (SH 95) is a 14.33 mile (23.06 km) long north–south state highway in the U.S. state of Colorado. SH 95's southern terminus is at U.S. Route 285 in Denver and the northern terminus is at US 36 in Westminster.

Colorado State Highway 66

State Highway 66 is a 22.7 mi (36.5 km) long east-west state highway in Boulder and Weld counties in Colorado. The highway extends from the foothills of the Rocky Mountains at a junction with U.S. Route 36 and SH 7 southeast of Lyons, proceeding east through the northern edge of Longmont, to Platteville where it ends at US 85. Although a number of western states retain their "state highway 66" as the decommissioned US 66, the "Mother Road" did not run through Colorado, and SH 66 has no connection to the famed Historic Route 66.

There are 13 active business routes of Interstate 70 in Colorado. I-70 spans Colorado in an east-west fashion, holding many business loops and spurs along the way varying from lengths of 0.22 mi (0.35 km) to 27.47 mi (44.21 km), with a total of 55.51 miles. Four other business routes also used to exist within the state.

Colorado State Highway 119

State Highway 119 is a 63.7-mile-long (102.5 km) state highway in north central Colorado. It extends in a southwest to northeast direction, from a junction with U.S. Route 6 in Clear Creek Canyon between Golden and Idaho Springs to a junction with Interstate 25 (I-25) east of Longmont. The southwest portion of the road is a scenic mountain drive providing dramatic vistas of the Front Range, while the northeast portion is a busy interurban thoroughfare. The city of Boulder separates these two vastly different sections of SH 119.

State Highway 88 (SH 88) is a 21.734-mile-long (34.977 km) state highway in Denver and Arapahoe counties within the U.S. state of Colorado. SH 88's northern terminus is at Interstate 70 Business, U.S. Route 40 and US 287 in Denver, and the eastern terminus is at SH 83 in Aurora.
