University Avenue (U.S. 189) is the primary corridor connecting the Orem-Provo area to the Heber Valley. In the area of 600 South in Provo, the roadway crosses over the Union Pacific Railroad switching yard and the current end-of-line for UTA’s FrontRunner network. The viaduct was originally built in 1966 and has been rehabilitated several times during the past 50 years, including some emergency repairs that were completed in late 2020. Based on previous rehabilitation efforts, and the findings of recent routine inspections, the structure has reached the end of its anticipated service life. UDOT recently completed a traffic analysis to determine the level of environmental study that will be needed.
Replacing the viaduct will provide a bridge that meets current design standards, improves visibility for drivers, stays within the existing footprint and will have a service life of approximately 75 years. As part of the environmental process, UDOT will also consider how to incorporate active transportation across the bridge. Maintaining this crossing is vital to the surrounding area and a key transportation facility for the traveling public.
