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.
