Project Facts

Project No. A009(891)
Key No. 09891
MP 360.9 to 363.3

This project reconstructed 2.1 miles of highway just west of the Portneuf River Bridges project, from 12th Street to Crystal Springs Road. The project expands the highway section to four lanes of travel. The improvements will increase safety and capacity on U.S. 30, a heavily-used trucking route. This segment is part of a larger effort to improve U.S. 30 between McCammon and Soda Springs.


U.S. 30 is a vital link for commerce between Wyoming and Idaho. Of the approximately 3,000 vehicles that travel between McCammon and Lava Hot Springs every day, large commercial trucks make up forty percent of the traffic. With improvements, this corridor will safely handle the projected growth to 5,000 vehicles every day by 2024. Prior to improvements, this section was a two-lane facility with occasional center turn lanes. It provided little opportunity to pass safely, making the combination of large trucks and local traffic very dangerous.

Prior to this project becoming a part of the GARVEE Program, District 5 performed the preliminary design, environmental assessment, and achieved an environmental Finding of No Significant Impact (FONSI) determination in 2002 using formula funds. Formula funds were also used to acquire all right-of-way.


Preliminary design was completed by ITD prior to this project becoming part of the GARVEE Program. Right-of-way was completed in November 2007 and final design was completed in January 2009. Construction began in May 2009 and achieved substantial completion in August 2010.
