The Shoup Bridge on Williams Creek Road near US 93 crosses the Salmon River approximately five miles south of Salmon, ID. Williams Creek Road provides access to the Salmon-Challis National Forest, recreational areas and commercial mining operations. It also provides local residents with access and emergency services. Shoup Bridge needed to be replaced in order to continue service as a critical transportation link. The Western Federal Lands Highway Division led a project to replace the existing single-lane bridge with a two-lane bridge and chose Internally Cured Concrete in an effort to add service life to this bridge.
