Signal Upgrades on I-70 B and US 6 in Clifton

October 27, 2011 - Northwestern Colorado/CDOT Region 3 - MESA COUNTY – The Colorado Department of Transportation has begun a project to upgrade the traffic signals at the intersection of I-70B (business route) and US 6 in Clifton.

At this intersection, crews will upgrade outdated traffic signals and signal poles and install fiber optic cable alongside US 6 west to Warrior Way—extending CDOT’s interconnectivity network (linking signals for improved traffic flow).

The project was contacted to WL Contractors of Arvada for $598,704.

TRAVEL IMPACTS - The work is scheduled for completion by mid-December. During daylight hours (currently 7 a.m. to 5 p.m.) motorists will encounter some single-lane closures approaching the intersection. Access to businesses will be maintained. The speed limit will be reduced to 40 mph through the work zone. CDOT thanks motorists for going Slow for the Cone Zone!
