Traffic switch on CO 9 in Frisco begins

Travel Advisory

June 3, 2021 - Northwestern Colorado - Expect delays and crews on the roadway

SUMMIT COUNTY – Starting Thursday, June 3, crews will realign northbound and southbound lanes of Colorado Highway 9 in Frisco. Motorists should plan for right lane closures, lane shifts, striping crews, signal work and flaggers on the roadway, with possible 20-minute traffic delays. The traffic switch is to allow crews to complete underground work along CO 9 in Frisco, from Main Street to 8th Avenue. (8th Ave. in this location is sometimes shown on navigation apps as Teller Ave.) The underground work and other tasks are necessary to prepare for a temporary roundabout at the intersection of 8th Avenue and CO 9, as well as to prepare for signal improvements at the intersection of Main Street and CO 9. A permanent roundabout will be in place at the intersection of 8th Ave. and CO 9 when the project is complete this fall.

For the safety of motorists and workers, drivers are reminded to obey all posted speed limits through the project. Reduced lane widths and reduced speed limit of 35 mph will be in effect until further notice. SEMA Construction Inc. is the prime contractor for this project.

Travel Impacts 

Daytime work hours range from 7 a.m. to 7 p.m. Monday through Friday. Vehicles are reduced to a single lane in both directions for the duration of the 2021 construction season. Motorists should expect flaggers on the roadway to help guide them through the construction zone or when work is near intersections and the recreation path. The speed limit is reduced to 35 mph, and work zone fines are doubled. Motorists should plan for possible 20-minute traffic delays.
