Southway Bridge

Southway Bridge is a four-lane road bridge spanning the Snake River and linking Clarkston to Lewiston. It carries traffic between Fleshman Way on the west side and Bryden Canyon Road on the east side.

The bridge was built in the early 1980s following the construction of Lower Granite Dam, which altered the river's water conditions. The project was funded by the Army Corps of Engineers to address the changed circumstances.

The bridge stands as a testament to regional cooperation between Washington and Idaho states, enabling community connections across the Snake River.

The bridge serves residents in the region as a main connection to local destinations like the airport. Visitors should know this is a heavily used connector road that requires patience during peak times.

The structure solved a specific traffic problem where the previous single-lane crossing under the Interstate Bridge became congested during boat passages. The new route eliminated these delays and provided a modern alternative for through traffic.
