SH 119 Boulder East Resurfacing Project starts Monday

April 29, 2016 - Northeastern Colorado/CDOT Region 4 - Project completion is scheduled for October

BOULDER COUNTY – The Colorado Department of Transportation (CDOT) will begin Monday on a $12 million project along SH 119 (Diagonal Highway) just east of Longmont in Boulder County from mile points 44.995 to 54.42, in an effort to improve the rideability and traffic operations for motorists in early May.

In addition to resurfacing work, guardrails and bridge rails will be replaced and minor bridge repairs will be performed and signs replaced along the construction zone. Motorists can expect the project to be completed by October.

During the duration of the project, crews will work to minimize any traffic impacts during construction. Lanes-shifts and lane closures may occur and will be directed by flaggers at both ends of the work zone. All construction requiring lane closures will occur between the hours of 9 a.m. and 7 p.m. in the southwest direction, and between the hours of 7 a.m. to 3 p.m. in the northeast direction. Work not requiring lane closures will occur between the hours of 7 a.m. to 7 p.m. in both directions.
