State Highway 46 (SH 46) is a state highway in Colorado that connects Golden Gate Canyon State Park to State Highway 119 near Black Hawk.
SH 46 runs 6.6 miles (10.6 km), starting at a junction with SH 119 northwest of Black Hawk. It runs east through Golden Gate Canyon State Park. At the Jefferson County line the state highway ends and the road continues east as Golden Gate Canyon Road (County Road 70) over Golden Gate Pass to SH 93 in northern Golden.
SH 46 was formerly part of State Highway 58. As designated in 1912–1914, Primary Road No. 58 connected Central City and Golden, leaving Central City on Gregory Street (former SH 279) and following present SH 119 alongside North Clear Creek. It turned northeast on Smith Hill Road and then, as originally defined, along present Golden Gate Canyon Road (including about 1⁄2 mile (0.80 km) of modern SH 46) past Guy Hill. [2] Some early maps, however, show the state highway following Crawford Gulch Road significantly north of Guy Hill. [3] By May 1923, the west end had been shifted north to SH 119 north of Central City and Black Hawk, [4] and at about the same time the Golden Gate Canyon Road alignment was permanently adopted. [5] (SH 58 was also extended east from Golden to Denver along what had been Primary Road No. 1, and the number remains to this day on a parallel freeway replacement.) As part of a 1953 reorganization that eliminated a large number of state highways, SH 58 was cut back to its modern Denver-to-Golden extent. [4] Former SH 58 west of Golden Gate Canyon State Park was reacquired in 1972-1973 as a new State Highway 46 and paved in 1974. In 1985-1986 SH 46 was extended east to the county line along already-paved county road, and at the same time Jefferson County completed the paving of its section of Golden Gate Canyon Road. [3]

Golden is a home rule city that is the county seat of Jefferson County, Colorado, United States. The city population was 20,399 at the 2020 United States Census. Golden lies along Clear Creek at the base of the Front Range of the Rocky Mountains. Founded during the Pike's Peak Gold Rush on June 16, 1859, the mining camp was originally named Golden City in honor of Thomas L. Golden. Golden City served as the capital of the provisional Territory of Jefferson from 1860 to 1861, and capital of the official Territory of Colorado from 1862 to 1867. In 1867, the territorial capital was moved about 12 miles (19 km) east to Denver City. Golden is now a part of the Denver–Aurora–Lakewood, CO Metropolitan Statistical Area and the Front Range Urban Corridor.
U.S. Route 40 or U.S. Highway 40 (US 40), also known as the Main Street of America, is a major east–west United States Highway traveling across the United States from the Mountain States to the Mid-Atlantic States. As with most routes whose numbers end in a zero, US 40 once traversed the entire United States. It is one of the first U.S. Highways created in 1926 and its original termini were in San Francisco, California, and Atlantic City, New Jersey. US 40 currently ends at a junction with I-80 in Silver Summit, Utah, just outside Salt Lake City. West of this point US 40 was functionally replaced with I-80, and as these segments of I-80 were constructed the western portion of US 40 was truncated several times.
State Highway 14 in the U.S. state of Colorado is an east–west state highway approximately 237 miles (381 km) long, making it the longest state highway in Colorado.

After leaving Morrison, it then heads east passing by Littleton and through Highlands Ranch before interchanging Interstate 25 in Lone Tree, where the freeway continues as a tollway and where the state highway designation ends.

U.S. Route 36 is a United States highway that travels from Rocky Mountain National Park, Colorado to Uhrichsville, Ohio. In Colorado, the highway traverses an east–west route mostly in the northern portion of the Great Plains. At its west end, the road connects several small mountain towns such as Estes Park and Lyons to the larger metropolitan areas of Boulder and Denver. As it continues eastward, it connects to several other small towns and rural highways on the plains before crossing the state line into Kansas.
U.S. Highway 385 (US 385), also known as the High Plains Highway north of Cheyenne Wells, is the easternmost significant north–south state highway in the U.S. state of Colorado, and many of the state's major east–west routes intersect with US 385 before crossing into neighboring Kansas and Nebraska. It enters the state from Oklahoma while overlapped with US 287, but splits at Lamar to follow its own route through the Eastern Plains to Nebraska.
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.
State Highway 72 is a 51-mile-long (82 km) state highway passing through the foothills and the eastern edge of the Front Range. Its southern terminus is at Interstate 70 (I-70) in Wheat Ridge, and its northern terminus is at SH 7 east of Allenspark.
