The bridge has a 60.9-metre (200 ft) main span. It was designed by Harrington, Howard & Ash, the predecessor of HNTB. It was rehabilitated in 2001 and is a through-truss vertical-lift bridge with 36.5 m (119.8 ft) clearance for shipping.[2]

On August 11, 2001, the bridge was struck by the MS Windoc (1959) when the lift span was lowered before the ship cleared the structure. The ship caught fire. After minor repairs to the bridge, it reopened to vehicular traffic on November 16, 2001.[3]
