DOT begins lighting project on I-70 Beavertail Tunnel next week

April 20, 2017 - Northwestern Colorado/CDOT Region 3 - Speed limits to be strictly enforced

Mesa County- Beginning Monday, April 24 the Colorado Department of Transportation (CDOT) and contractor Sturgeon Electric will begin a lighting project on Interstate 70 Beavertail Tunnel. The project limits are from mile point (MP) 48 - 52.  The project has an anticipated completion date of November 2017.

The scope of work includes: repairs to the eastbound service road, structural coating of the tunnel liner, concrete patching, structural repair and adding luminaire lighting.  Luminaire light is an LED light that will be permanently installed on the top circumference of the tunnel.  Repairs on the eastbound service road will include surgical repairs, a HMA (hot mix asphalt) overlay, and setting temporary barriers.

TRAVEL AND ACCESS IMPACTS: For several days next week, the eastbound service road will be closed to all traffic 24/7 while the overlay takes place.  Motorists can expect a speed limit reduction of 40 mph and a single lane closure for the eastbound lane, flaggers will be present.  For the duration of the project, eastbound traffic will detour onto the single lane service road, adjacent to the Beavertail Tunnel, along the canyon wall for 1.2 miles then connect back onto I-70.  The project will be in operation Monday - Friday, 7:00 am - 5:00 pm.
