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 (Spanish).  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.

Access to Local Businesses

Local businesses will remain open during construction and reasonable access will be provided.

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.
