Designed to carry two rail lines, two lanes of auto traffic and a pedestrian lane this bridge was 70 feet wide. It was reported to be the largest and heaviest of its kind in the world. The bridge is a trunnion bascule bridge. It was designed by the master of trunnion bascule bridge design, Joseph B. Strauss who also was the chief engineer for the Golden Gate Bridge. One of the rail lines on the bridge was a trolley line which was removed in the 1940's. The bridge was closed to vehicular traffic in 1978 due to safety concerns and is little used and left in the up position most of the time. The harbor commission has long term plans to replace it which it announced in 1994.
