The Southway Bridge is a highway bridge spanning the Snake River between Clarkston, Washington, and Lewiston, Idaho. It connects Fleshman Way in Clarkston with Bryden Canyon Road in Lewiston, and provides residents of the Lewiston Orchards with access to State Route 129, as well as providing Clarkston residents with access to the Lewiston–Nez Perce County Airport. The bridge was opened to traffic on August 3, 1982, at a cost of $21 million, after several delays due to repairs.[1][2] The Bryden County Road project linking the bridge to the Lewiston Orchards was completed in 1999.[3][4]
The bridge was built to supplement the Interstate Highway Bridge (nicknamed the "Blue Bridge") to the north, which was sometimes closed to traffic while the bridge was raised to allow large boats to cross underneath.
