CR 314 Idaho Springs to Veterans Memorial Tunnel

Project Complete!

The Colorado Department of Transportation started construction on County Road 314 from east of Idaho Springs to the Veterans Memorial Tunnels in early October 2021. Crews enhanced the existing road and added improvements. American Civil Constructors was selected for this project.

The project is located at Mile Point 0 and extends 1.3 miles east to MP 1.26. Work will include road widening and paving, installation of retaining walls and guardrails, a pedestrian path and bridge over Clear Creek, drainage improvements, erosion and traffic control management, and signing and striping. Traffic impacts expected on the project include shoulder closures, single lane closures, and alternating traffic along CR 314.

The CR 314 pedestrian bridge along the Lancaster Trail will be placed on the east side of the treatment plant in early November. The bridge setting will take three days, and will connect CR 314 to the Lancaster and Greenway Trail. The bridge construction will continue through the end of November.

Work will include road widening and paving, installation of retaining walls and guardrails, a pedestrian path and bridge over Clear Creek, drainage improvements, erosion and traffic control management, and signing and striping.
