The Marion Street Bridge is an automobile bridge located in Salem, Oregon, United States. It spans the Willamette River to connect Salem and West Salem, and acts as a conduit for Oregon Route 22. The bridge carries vehicular traffic one way westbound. Traffic includes two lanes that flow onto the bridge from Marion Street, vehicles turning right from Commercial Street, and traffic from a quarter-loop on-ramp from Front Street that was added in 1981. Construction began in December 1952 and the bridge opened in 1954, after taking nearly three years to complete.
