Twin Falls, ID Could See a New Snake River Bridge

The ITD is proposing a new bridge spanning the Snake River, a major infrastructure project aimed at future-proofing the region's transportation network. With forecasts predicting an additional 37,000+ new residents by 2050, the need for a solution is pressing. ITD states that a new crossing would serve multiple critical functions: improving daily commute flows, boosting safety in a high-accident corridor, offering an alternative route to ease pressure on U.S. Highway 93, and creating essential redundancy within the local roadway system.

Four primary route options have been shortlisted for the project. Two potential paths would originate near Jerome, requiring a bridge roughly 1,400 feet long to cross the river west of Twin Falls. The other two alternatives are situated closer to the heart of the Magic Valley, near Twin Falls, and would necessitate longer bridges of approximately 1,500 feet.

The department is also evaluating a variety of architectural designs, from sleek cable-stayed and suspension bridges to more utilitarian rigid frame and box girder structures. This proposed river crossing is one part of a broader strategy to enhance mobility in the area. Other key projects include significant improvements to the intersection of Blue Lakes Boulevard and Pole Line Road, as well as plans to either widen or completely replace the aging Hansen Bridge.
