The Utah Department of Transportation (UDOT) is improving the eastbound and westbound I-80 bridges at Echo (milepost 168) and Wanship (milepost 155) in Summit County. This work will include installing new barriers or guardrails at some locations and replacing the bridge approach slabs – the part of the structure that carries traffic between the road and the top of the bridge.

Work began on westbound I-80 at the Echo bridge on Monday, Oct. 3, and will last through November 2022, pause through the winter, and resume in spring 2023. Spring work will last for approximately two months and include the eastbound I-80 bridge at Echo and the I-80 bridges at Wanship.

To accommodate this work, the I-80 bridge under construction will be reduced to one lane. The inside lane will remain open while crews complete work on the outside lane. Once finished, the outside lane will remain open while crews complete work on the inside lane.


  • Daytime work
    • 7 a.m. to 5 p.m.
    • Monday through Friday
  • Reduced speed limit
  • Traffic restrictions in place 24/7
  • Minor delays


Lanes will be narrowed to 11 feet and shoulders narrowed to 2 feet. Wide loads should exit westbound I-80 at Echo (Exit 169) and enter westbound I-80 from the on-ramp at Echo to avoid the lane width restriction.
