The Interstate Highway Bridge crosses the Snake River, between Clarkston, Washington and Lewiston, Idaho. The bridge carries U.S. Route 12 (US 12) across the state line between Washington and Idaho, and is maintained by the Washington State Department of Transportation. It was built in 1939 and is 1,424 feet (434 m) long. It is nicknamed the "Blue Bridge" locally.[1][2]

The bridge was the primary route between Lewiston and Clarkston, until the Southway Bridge was constructed in the 1980s.[3][4]
