U.S. Highway 6 - Sixth Avenue (Westbound)

U.S. 6 consists of several signed segments in between the segments it silently shares with Interstate 70 and Interstate 76 through Colorado. In Denver, U.S. 6 follows 6th Avenue, a freeway that parallels Interstate 70 to the south. Upon reaching Interstate 25, U.S. 6 silently merges with Interstate 25 northbound, then continues northeast along the Interstate 76 corridor.

U.S. 6/6th Avenue West
This "To U.S. 6" shield is located on the transition ramp from southbound Interstate 25 onto westbound U.S. 6; technically the ramp is U.S. 6, since it is transferred from southbound Interstate 25 to westbound U.S. 6. Photo taken 02/02/02.
Westbound U.S. 6 approaches Junction Colorado 88 to U.S. 287, Federal Boulevard. Colorado 88 follows Federal Boulevard south to Belleview Avenue, then turns east on Belleview Avenue to meet Interstate 25 at Exit 199 just south of Interstate 225. Looking north, Colorado 88 continues north for less than a mile before ending at its interchange with Business Loop I-70/U.S. 40-287/Colfax Avenue. Colorado 88 ends, and U.S. 287 takes over northbound Federal Boulevard. Photo taken 11/10/03.
The sign for the next exit along westbound, Lowell Boulevard and Perry Street, is affixed to the overpass carrying Federal Boulevard (Colorado 88) over U.S. 6. Photo taken 02/02/02.

Westbound U.S. 6 approaches Lowell Boulevard and Perry Street. Photo taken 11/10/03.
Six lanes are crammed into a tight right of way along U.S. 6, thus reducing the width of the shoulders. Photo taken 02/02/02.
Westbound U.S. 6 along Sixth Avenue. The freeway here is very narrow, and it is squeezed in between houses. Photo taken 02/02/02.
Westbound U.S. 6 approaches Colorado 95, Sheridan Boulevard. Like many routes in Denver, this state highway stays within a rough grid pattern, and it connects to Interstate 76 along the same trajectory. Photo taken 02/02/02.

The next exit along westbound is for Colorado 121, Wadsworth Boulevard. Photo taken 11/10/03.
Westbound U.S. 6 at Colorado 121, Wadsworth Boulevard. Carr Street and Garrison Street are at the next exit. Note the tall sound wall erected for the benefit of the neighboring residents. Most homes along this freeway are built right up to the freeway itself, with minimum right of way to spare. Photo taken 11/10/03.
View of U.S. 6 exit ramp to Colorado 121. Note the short deceleration lanes. With such a sharp exit, this freeway is not at Interstate standards. Photo taken 02/02/02.
Westbound U.S. 6/6th Avenue approaches the Carr Street/Garrison Street exit, 0.25 mile. The following exit is Junction Colorado 391/Kipling Street. Photo taken 11/10/03.
People could jump from their front yard onto the freeway at this location on westbound just before the Colorado 391 exit. Photo taken 02/02/02.
Westbound U.S. 6 approaches Colorado 391/Kipling Street. The first substandard sign is a throwback from when all signage on the U.S. 6 freeway was written in all-capital letters. Most of these signs, but not all, have since been replaced. Photo taken 11/10/03.
Colorado 391, Kipling Street, is a major north-south arterial route through the western part of metropolitan Denver. It continues north to meet Interstate 70. The Denver Federal Center is located off Colorado 391/Kipling Street southbound. Photo taken 11/10/03.
Westbound U.S. 6/6th Avenue at Junction Colorado 391/Kipling Street. The second approach sign for Colorado 391/Kipling Street is more standard than the previous one. Photo taken 11/10/03.
The next exit along westbound is Simms Street/Union Boulevard, 0.75 mile. Simms Street leads north into the Applewood neighborhood of Lakewood, and Union Boulevard leads south toward Bear Creek. Photo taken 11/10/03.
To alleviate confusion regarding the speed limit on the U.S. 6/6th Avenue freeway versus the frontage road, this speed limit sign has a small "Freeway" banner affixed beneath the sign so that confused drivers on the frontage road will not think their speed limit is also 65 miles per hour. The next exit is Simms Street/Union Boulevard. Photo taken 11/10/03.

Westbound U.S. 6 approaches Indiana Street, three-quarters of a mile. Photo taken 11/10/03.
Westbound U.S. 6 at the Indiana Street exit, which is the last exit before reaching Interstate 70. Photo taken 11/10/03.
Westbound U.S. 6 approaches Junction Interstate 70, one mile. The freeway section only continues briefly beyond this interchange as U.S. 6 enters Golden, as it meets a traffic signal after the Interstate 70 overpasses. Photo taken 11/10/03.
Westbound U.S. 6 approaches Junction Interstate 70, 0.75 mile. Interstate 70 leads west into the foothills and mountain areas of the Rocky Mountains, passing through Idaho Springs, Vail, Eagle, Glenwood Springs, and Rifle before reaching the city of Grand Junction some 230 miles west of here. There is no direct access to eastbound Interstate 70; use Business Loop I-70/U.S. 40/Colfax Avenue east instead. Photo taken 11/10/03.
Westbound U.S. 6 approaches Junction Interstate 70. The U.S. 6 freeway section continues briefly beyond this interchange as U.S. 6 enters Golden, but it meets a traffic signal at the intersection with Business Loop I-70/U.S. 40/Colfax Avenue. Photo taken 11/10/03.

The U.S. 6/6th Avenue freeway ends in Golden after the exit ramp to eastbound Business Loop I-70/U.S. 40/Colfax Avenue. The next traffic light provides access to westbound Business Loop I-70/U.S. 40/Colfax Avenue. Photo taken 11/10/03.
Colorado 470, which forms the belt route around the southwestern suburbs of Denver, begins its southerly journey at its interchange with U.S. 6. The freeway was extended north to U.S. 6/6th Avenue as part of a construction project during the late 1990s/early 2000s. Currently, there are no plans to extend Colorado 470 north of U.S. 6, although there continues to be some consideration to resurrect the once-proposed and currently dead W-470 northwestern belt route. However, local opposition makes any connection between Colorado 470 and the Northwest Parkway very unlikely. Photo taken 11/10/03.
Westbound U.S. 6/6th Avenue reaches Colorado 470/Johnson Road. Photo taken 11/10/03.
After the junction with Colorado 470, U.S. 6 remains a four-lane expressway as it approaches Golden. Despite the fact that U.S. 6 is heading northwest and no longer a freeway at this point, it is still known as 6th Avenue. Photo taken 08/29/04.
This photo provides a view of the westbound U.S. 6/6th Avenue expressway. The expressway avoids most of Golden, choosing to remain west of the residential and downtown sections of that city. Photo taken 08/29/04.
This mileage sign provides the distance to Dillon, Central City, and (somewhat surprisingly) Steamboat Springs. Since U.S. 6 does not go to Steamboat Springs, it seems more fitting that an Interstate 70 control city, such as Grand Junction be used. Photo taken 08/29/04.
The next major intersection after the Colorado 470 interchange is the junction with Colorado 93 north to Boulder and Colorado 58 east through Golden to Denver via Interstate 70. While Colorado 93 is largely a two to four-lane highway, Colorado 58 becomes a freeway as it passes through Golden en route to Wheat Ridge. Photo taken 11/10/03.
To reach Colorado 119 to the gambling communities of Black Hawk and Central City in Gilpin County, follow U.S. 6 west. Photo taken 11/10/03.
To continue west on U.S. 6, the two left lanes turn left at this intersection. Colorado 93 begins its journey straight ahead, and Colorado 58 turns right from this intersection. Both Colorado 93 and Colorado 58 come to their respective ends at this intersection. Photo taken 08/29/04.
Span wire supports the traffic signals above the U.S. 6, Colorado 93, and Colorado 58 intersection. To the east, Colorado 58 is a freeway; to the west, U.S. 6 continues into Clear Creek Canyon. Photo taken 08/29/04.
View of westbound U.S. 6 after the Colorado 58/93 intersection. U.S. 6 enters the Clear Creek Canyon, following a winding two-lane road that meets Colorado 119 at the Jefferson-Gilpin-Clear Creek County Line and ultimately connects with Interstate 70 at Exit 244. There are two tunnels for U.S. 6 between Colorado 119 and Interstate 70. Photo taken 11/10/03.
