In the U.S. state of Colorado, U.S. Route 50 is a major highway crossing through the lower midsection of the state. It connects the Western Slope with the lower Front Range and the Arkansas Valley. The highway serves the areas of Pueblo and Grand Junction as well as many other smaller areas along its corridor. The long term project to upgrade the highway from two lanes to a four lane expressway between Grand Junction and Montrose was completed in January 2005. Only about 25% of the remainder of highway 50 in Colorado is four lane expressway.

U.S. Highway 50 begins in Colorado at the Utah state line, concurrent with Interstate 70 as well as U.S. Highway 6. At Interstate 70 exit 11, U.S. Highway 6 & 50 end their concurrency with Interstate 70 and begin using the old highway alignment directly north of Interstate 70 while they travel through the communities of Mack, Loma, and Fruita. These communities were bypassed by Interstate 70. Near mile marker 15 the Colorado River adjoins Interstate 70 and runs nearby for the next 16 miles (26 km). In Fruita routes 6 and 50 intersect State Highway 340, the gateway to the Colorado National Monument. The monument's sandstone canyons and rock spires are visible to the south from the highways.
