U.S. 30, Topaz Bridge
U.S. 30, Topaz Bridge
Project Number A009(897)
This project constructs a new bridge to replace the existing Topaz Bridge. This project is part of a larger effort to improve U.S. 30 between McCammon and Soda Springs.
The Topaz Bridge project includes final design and construction of a U.S. 30 bridge over the Union Pacific Railroad and the Portneuf Marsh Valley Canal, and associated road work. It also provides final design of approximately seven acres of wetland mitigation at the Price Road mitigation site.
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 substantial completion is anticipated in September 2012.
