Bridge 11 (also known as the Allanburg Bridge) is a vertical lift bridge over the Welland Canal within the City of Thorold and community of Allanburg. The location was used for the groundbreaking ceremony for the canal. Constructed in the late 1920s and was completed and placed in commission at opening of navigation in 1930. The bridge carries Hwy 20 connecting Niagara Falls to Fonthill.
The bridge has a 60.9 m (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.
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.
