Welland Canal Bridge 11 Welland Canal Bridge 11 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, Ontario, Canada. The location was used for the groundbreaking ceremony for the canal. It was constructed and completed in 1930. The bridge carries Hwy 20 connecting Niagara Falls to Fonthill. The bridge has a 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 clearance for shipping. On August 11, 2001, the bridge was struck
Welland Canal, bridge 13 in late 2008. Another closure occurred in 2014 to allow for repainting and preservation of the entire structure. The bridge has become the symbol of the City of Welland. Even though the bridge towers no longer serve any practical purpose, their preservation has been given a priority owing to their historical significance. Welland is making a concerted effort to revitalize the downtown area. The new Civic Square is just a block to the east of the bridge, and an observation platform built beside the canal offers views of the bridge. Nevertheless, business has not flocked back to the downtown area.
