Purpose of Closures:

The Utah Department of Transportation will place multiple girders onto the base foundation of the new eastbound I-84 bridge.

Additional Lane Closures:

Additional eastbound (EB) shoulder and outside lane closures may be necessary on occasion over the next several months.  Dates and times TBA.  We will share any upcoming closures via the website, social media, and UDOT Traffic app as they become available.  Closures schedules are permitted as weather and material availability permits. Drivers should be prepared for barrels on the roadway to guide them into the open lanes past the construction zone.  More details on [ Impacts and Updates Tab ]

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.
