Travel Advisory

April 16, 2021

ARAPAHOE & ADAMS COUNTIES — On April 19, the Colorado Department of Transportation and Brannan Sand and Gravel will begin work on resurfacing Colfax Avenue (U.S. 40) between Sable Boulevard and Peoria Street. Work on this project will improve driving conditions and safety along this 1.75-mile stretch of Colfax Avenue, including pavement resurfacing, curb ramp improvements for ADA compliance, and intersection improvements at Colfax and Peoria. The resurfacing will be completed through mill and paving, which involves removing a 2 to 2.5-inch layer of existing asphalt and putting new asphalt on top of the milled surface. 

Beginning in April, crews will complete concrete work on the curb ramps. Once concrete work is completed, which is anticipated by the end of May, crews will begin resurfacing Colfax Avenue. Motorists can expect day and night time lane closures. Crews will work from Sable Boulevard westbound to Peoria Street.
