Travel Advisory

August 13, 2021 - Northeastern Colorado - Motorists can expect delays

WELD COUNTY – The Colorado Department of Transportation, in partnership with Interface Communications, will begin work on Aug. 16 to install four new traffic signals. Crews will work to install the traffic signals at the intersections of Colorado Highway 257 and US Highway 34 on- and off-ramps in Greeley. Work will also include minor striping changes.

Signalization project map

“In 2017 a signal warrant study determined that signalization of the on/off ramps would improve the overall safety and operations of this interchange. This signalization will provide safer access and improve the flow of traffic during peak periods,” said Regional Transportation Director Heather Paddock.

Travel Impacts 

  • Along CO 257, there will be shoulder closures and single lane closures at all four intersections and on- and off-ramps. 

  • Most often, traffic impacts are expected to be minimal and will be maintained in two-lane configurations, with traffic flowing in both directions. 

  • Occasional lane closures and intermittent traffic stops are to be expected.

  • Motorists can expect lane closures, lane shifts, survey crews, and flaggers on the roadway, and work will include the placement of signal poles. For the safety of motorists and workers, drivers are reminded to obey all posted speed limits through the project. Work is expected to be completed by December 2021.

  • General working hours will be Monday through Friday 7 a.m. to 5 p.m.
