Work on US 85 to resume at the end of March

March 24, 2016 - Northeastern Colorado/CDOT Region 4 - This project is expected to end this Fall .

WELD COUNTY — The Colorado Department of Transportation will restart work on US 85 between Ault and the Wyoming border at the end of this month. The project is expected to last until this Fall, when travelers will have a nice, smooth and safe road to drive on.

In the beginning of April, crews will begin realigning US 85 between the north end of Ault and County Road 86. In mid-April, crews plan to widen the roadway shoulder areas north of Pierce to County Road 95 where the 2015 season left off. Widening of the shoulder between Pierce and County Road 86 is also anticipated during this time.

Removal and replacement of storm drain and irrigation culverts, structures that cross US 85 at various locations between Ault and Pierce, will occur during the end of March and into April. Pending spring rain, snow storms and temperature limitations, crews also plan to begin the roadway reclamation process in anticipation of asphalt paving between late April and early May.

TRAVEL IMPACTS: Travelers should expect delays of up to 15 minutes during the road improvements. Pilot cars will direct travelers through several single-lane closures spanning up to two miles each throughout the project site. Construction work hours will run from 7 a.m. to 5 p.m., Monday through Friday. Speed limits through the project work zone will be reduced to 40 mph during the day. Once crews begin full-depth reclamation later this year, the speed limit will be 40 mph during the day and through the night, due to uneven lanes. Width restrictions of 12 feet will be in place from 6 a.m. to 6 p.m. Motorists should exercise caution at all times while navigating the work zone.
