Senator George Sellar Bridge

The Senator George Sellar Bridge spans the Columbia River using a steel arch between two concrete piers, with five lanes for vehicle traffic. Cantilever sections extend outward to concrete supports that sit high on each riverbank.

The bridge was built in 1950 and replaced an older structure that served the site since 1908. Its steel design earned recognition from the American Institute of Steel Construction for engineering excellence.

The bridge links communities across the Columbia River and makes daily travel possible between the towns on each bank. It represents how engineering works shaped the area's growth and connection.

The bridge underwent renovation in 2009 and remains an active roadway with regular traffic across it. Visitors should be aware that walking or stopping on the structure requires caution due to vehicle movement.

The structure uses a tied-arch design where cables bind the arch to the bridge deck itself. This method allows for long spans across the river without needing massive supports in the middle of the water.
