Project Description:

The Utah Department of Transportation (UDOT) will reconstruct 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.
