West Street Bridge
This bridge should be considered historically significant as one of the oldest unaltered examples of a reinforced concrete slab overpass on I-5. The bridge predates the formation of the Interstate Highway System. The bridge retains original concrete balustrade railings, and is curved at one end. The concrete slab is arched slightly adding to the aesthetics of the bridge.
