U.S. 30, Topaz to Lava Hot Springs

Project Facts

Project Number: A010(455)
Key Number: 10455
MP 365.3-369.2

This project widened a 3.3-mile section of U.S. 30 from two to four lanes between Interstate 15 and the Lava Hot Springs community. The completed project will increase safety and capacity on U.S. 30, a heavily used trucking route. This segment is part of a larger effort to widen 13 miles of U.S. 30 between McCammon and Lava Hot Springs.

Description

Construction began in August 2006 and was completed in August 2008. The project included:

Highway expansion from two to four lanes with a center median, bridge replacement over the Portneuf River.

Background

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.

Schedule and Funding

The Topaz to Lava Hot Springs project was the first GARVEE project to break ground. It was included in the original GARVEE bonds approved by the 2006 Idaho Legislature, and is part of the larger McCammon to Soda Springs corridor for the GARVEE Transportation Program.

Construction cost was approximately $21 million.
