I-15 SR-77 Springville

The goal of this project was to replace the interchange at Utah State Route 77, I-15 and SR-147. The interchange needed reconstruction over a span of 2 miles, and was part of the Utah Department of Transportation’s (UDOT) design-build project.

Working closely with their partners, Wadsbro built a Single Point Urban Interchange (SPUI) and 2 major bridge structures. The city initially requested a completion date of May 2010 and had planned to direct traffic to a single lane with flaggers for at least a year.

Wadsbro and their partners suggested instead a full closure and detour, bringing forward the completion day and restoring normal traffic by Thanksgiving – just in time for Black Friday.
