1300 South Viaduct


1300 South Bridge Rehabilitation (500 W to 700 W)

Salt Lake City, in partnership with the Utah Department of Transportation, is rehabilitating the1300 South Bridge, also known as a viaduct, which spans over the Union Pacific Railroad (UPRR) and Utah Transit Authority (UTA) Tracks from 500 West to 700 West.

The original structure was built in the 1970’s and needs to be rehabilitated to meet safety and seismic requirements.

The 11 million dollar (6.8 mil construction) project includes:
  • Widening the bridge three feet and replacing the deck
  • Improving the bridge for pedestrians and bicyclists 
  • Improving the 700 West intersection and adding a new signal
  • Improving the bridge for safety, specifically seismic stability

Traffic Information

1300 South Bridge Closure

The bridge over the railroad tracks between 500 West and 700 West on 1300 South will be closed while construction takes place. This will expedite construction completion.  Click here for more project information and a route map which illustrates possible traffic routes for vehicles, pedestrians and bicyles during the bridge closure.  Vehicle routes which avoid at-grade railroad crossings are at 2100 South and 400 South.

Intersections and I-15 On-Ramps: 700 West, 500 West, and all 1300 South/I-15 on and off-ramps will remain open during construction. Some lane restrictions may be necessary while construction takes place.


Public Transportation

The project team is currently working with UTA to provide public transportation detour routes and will post the details on this website once they are completed.
