Welcome to S.R. 77
 

State Route 77 (also known as 400 South) is a primary transportation corridor for the communities of Springville and Mapleton and also serves as the main route to Hobble Creek Canyon. During the past decade, the area has experienced tremendous growth and projections indicate it will continue for the next several years.

In order to make long-term improvements to 400 South and the I-15 interchange, UDOT will:

  • Rebuild the existing freeway interchange as a single-point urban interchange (or SPUI);
  • Add an auxiliary lane along southbound I-15 between the two Springville interchanges;
  • Widen 400 South to four lanes from I-15 to Main Street in Springville;
  • Build a new bridge over the Union Pacific Railroad at 1500 West and replace the existing bridge at 400 West.

Once the project is complete, commuters, business owners and residents should experience:

  • Improved traffic flow at the I-15 interchange;
  • Improved travel times by separating all railroad crossings along 400 South and expanding the road to four lanes;
  • Safe and efficient access to businesses and properties.

$89 million of federal and state funds have been allocated for this project.
