US 85 in Pierce to Become a Two-lane Road Temporarily

April 12, 2016 - Northeastern Colorado/CDOT Region 4 - Crews will begin asphalt paving through the area

WELD COUNTY — Beginning Thursday, the Colorado Department of Transportation plans to make US 85 in Pierce between mile points 283 and 284 a two-lane road for asphalt paving operations. There will be one-lane northbound and one-lane southbound open throughout this closure. Crews anticipate fully reopening the highway by mid-June or early July.

During this time, there will also be two full intersection closures at Shafer Avenue and Park Avenue in Pierce on US 85. A detour will be specified near the project area to reroute traffic onto Main Street. Motorists should expect these closures until mid-May or early June.  This will speed up the process of asphalt paving on US 85 in order to complete the project in a timely manner.

In the beginning of April, crews began realigning US 85 between the north end of Ault and County Road 86. Currently, crews are beginning to widen the roadway shoulder areas north of Pierce to Country Road 95 where the 2015 season left off.

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 7:00 a.m. to 5:00 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.
