Nighttime lane closures begin on northbound I-25, westbound I-70 and eastbound I-76 for sign work

March 7, 2017 - Denver Metro Colorado/CDOT Region 1 - DENVER –Starting at 8 p.m. tonight, March 7, until 5:30 a.m. Wednesday, March 8, crews will temporarily close the northbound right lane of Interstate 25 between 17th Avenue and Speer Boulevard (Mile Points 210 to 212) to pour concrete supports for new sign structures.

All work is weather dependent and the schedule is subject to change.

Northbound I-25, westbound I-70 and eastbound I-76 will be subject to occasional, overnight single lane closures at the following locations for sign work:

  • Northbound I-25 between 17th Avenue and Speer Boulevard (MP 210 to 212)
  • Westbound I-70  between Sheridan Boulevard and Wadsworth Boulevard (MP 269 to 271)
  • Eastbound I-76 between Federal Boulevard and Pecos Street (MP 3 to 4)

This work is part of a project to remove and replace five aging overhead and cantilever sign structures in the Denver metro area. In early summer 2017, both northbound I-25 and westbound I-70 will be subject to two nights of full closure for overhead sign bridge removal. As the project progresses, for more information on planned highway closures including detour routes. Approximately one week in advance, information will be also be posted and on variable message signs.


The Colorado Department of Transportation and contractor partner, W.L. Contractors Inc., began the sign structure replacement project in late February and expect to complete the work in June. First, crews need to construct concrete supports for the new cantilever structures. Signs will be either replaced or reset on the new structures. Once the signs are placed, both northbound I-25 and westbound I-70 will be subject to full highway closures in order to remove the old sign bridges. Sixteen signs are set for replacement or relocation.PROJECT INFORMATION
