that spans the channel, and a arm that carries the counter-weight above the tracks. The bridge is no longer operable, but when constructed it was able to swing to the east, to an angle of 82.5˚ when parallel to the dock wall. The bridge was designed to carry a single railroad track, but also may originally have been intended for use by other vehicular traffic on Cherry Avenue. A sidewalk is cantilevered from the east side of the bridge.
