Project Type: Tunneling
Project Owner: Utah DOT
Project Completed: 2012
The Utah Department of Transportation needed to expand I-15 to handle the growing population in Provo County, Utah, in order to keep traffic flowing during construction trenchless methods of pipe installation underneath I-15 were used. We were a subcontractor with Provo River Constructors during this design build project. Using TBM and GBM tunneling methods, we completed 78 tunnels ranging from 15 inches to 96 inches in diameter.
