The new SR 6 Willapa River Bridge improves safety and mobility along a critical east-west route between Interstate 5 and the Southwest Washington coast. The new bridge replaces an aging structure that was built in 1929 and was too narrow to accommodate modern transportation needs. Additionally, the new bridge is built to better withstand earthquakes and flooding.
