Southway Bridge, Road bridge between Clarkston and Lewiston, United States
The Southway Bridge stretches across the Snake River with four lanes, connecting Fleshman Way in Clarkston to Bryden Canyon Road in Lewiston.
The Army Corps of Engineers funded this bridge in response to the 1975 construction of Lower Granite Dam, which created Lower Granite Lake.
The bridge stands as a testament to regional cooperation between Washington and Idaho states, enabling community connections across the Snake River.
Residents of Lewiston Orchards use this bridge to access State Route 129, while Clarkston residents reach the Lewiston-Nez Perce County Airport.
The bridge construction, completed in 1982 at a cost of 21 million dollars, reduced traffic delays caused by boat passages under the Interstate Highway Bridge.
