Perspective
US 85 enters Colorado from New Mexico running concurrently with Interstate 25 (I-25) but is not signed. Approaching the south side of Denver, US 85 leaves I-25 at exit 184. From there it heads west and north as a two-lane rural highway. It becomes an expressway near Chatfield Reservoir and the southern Denver suburbs of Littleton and Englewood, where it is commonly known as Santa Fe Drive. From just north of its intersection with C-470 to its northern intersection with I-25, it is known as the Navy SEAL Danny Dietz Memorial Highway. It continues north through Denver for a few miles before again joining with I-25 at mile marker 207. There it runs concurrently with US 87 as well as I-25 and heads north through downtown Denver. At exit 214, US 85 turns east and runs concurrently with I-70 and US 6 for about a mile where it exits with US 6 and heads northeast through Commerce City. In just a few miles the US 6/US 85 concurrency merges with I-76 at mile marker 9. They travel concurrently for three miles (4.8 km) until exit 12 when US 85 becomes an expressway and continues north out of the Denver area through Brighton.

From there it parallels I-25 for about 75 miles (121 km) passing through Fort Lupton, Platteville, Evans, Greeley, and Eaton before crossing into Wyoming.[citation needed]

US 85 originally followed some of the route that I-25 would later take.[2] In southern Colorado, US 85 originally was placed on city streets in Colorado Springs, Pueblo, and Trinidad until 1938 where the route was ultimately paved from one state to another, taking place at the present I-25 corridor. In Denver, US 85 followed Santa Fe Drive north to Iowa Avenue, three miles (4.8 km) south of downtown, then jogged east to Broadway, continuing about 4.5 miles (7.2 km) north to turn northeast onto Brighton Boulevard.[3]
Realignment
Starting in 1942, a realignment project took place in northeastern Denver, involving the opening of Vasquez Boulevard. Originally, US 85 ran along Brighton Boulevard from downtown going northeast and then was realigned along 46th Avenue to Vasquez Bouleard. Five years later, in Pueblo, the route took the downtown streets before the Greenhorn/Crow bypass opened two years later. In 1950, the Palmer Lake/Larkspur bypass opened, moving US 85 along with US 87 along the expressway. The expressway opened north of Pueblo in 1951, which allowed both US 85 and US 87 to use the expressway coming out of downtown until 1954.
In 1958, when the Valley Highway (now I-25) opened in Denver, US 85 no longer followed Broadway. It followed Santa Fe Drive north to Alameda, then transitioned onto I-25 until 46th Avenue, where it turned east toward Vasquez. When I-70 was connected to I-25 in 1964,[4] it became US 85 between I-25 and Vasquez.[3]
On October 1, 2007, part of the US-85 known as Nevada Avenue was relinquished and is now maintained by the City of Colorado Springs.[5]
