Project: I-15 Reconstruction - Salt Lake City
Summary
The I-15 Reconstruction Project involved the rebuilding and widening of a deteriorated, congested 17 mile stretch of Interstate 15, running through Salt Lake City. The project was necessary to accommodate the rapid growth the region was experiencing, much of which was due to in-migration from California.
