The Utah Department of Transportation (UDOT) has announced the completion of the Utah County I-15 Corridor Expansion (I-15 CORE) project ahead of schedule and under budget. The 24-mile design-build project added two travel lanes on I-15 in each direction, rebuilt or replaced 63 bridges and 10 freeway interchanges and replaced the existing roadway from Lehi to Spanish Fork with 40-year concrete pavement without decreasing the number of lanes during the majority of construction.

As one of the State of Utah’s largest highway construction projects, the $1.1 billion design-build project was completed in an unprecedented 35 months.

The I-15 CORE was built by Provo River Constructors, a consortium made up of Fluor Corporation, Ames Construction Company, Inc., Ralph L. Wadsworth Construction Company, Inc. and Wadsworth Brothers Construction Company, Inc.
