Upcoming Traffic Notice: 

Eastbound Lane Closures:

*Upcoming lane closure scheduled for Sunday, January 25 | 8 am to 5 pm 

Eastbound (EB) shoulder and outside lane closures have been necessary on occasion over the last several months. We will share any upcoming closures via the website, social media, and UDOT Traffic app as they become available.

Please remember to slow down when traveling through the work zone, especially when winter conditions are present. The posted speed limit in the work zone is 55 MPH during work hours, and speeding fines are doubled when workers are present.

Closures are expected to continue as weather permits. Drivers should be prepared for barrels on the roadway to guide them into the open lanes past the construction zone. More details regarding the closure schedule will be posted on the UDOT Traffic app, the project website, and broadcast through social media channels.

Walking Path Closed:

The walking/bike trail beneath I-84 along the river is currently closed for your safety while construction is ongoing. Please stay tuned for updates on when the trail will reopen.

Project Description:

UDOT is reconstructing the eastbound and westbound I-84 Weber River/Union Pacific Railroad bridges two miles east from the mouth of Weber Canyon in Weber County.  

This project will provide two new structures at this location, each with an anticipated service life of 75 years. These new bridges will also provide updated typical sections, along with improved detailing and geometry, resulting in a safer and more efficient facility for the traveling public. 

Please stay tuned for additional information as it becomes available.

See "Impacts & Updates" tab for latest traffic control information.
