Warrington Bridge is the name given to several historical bridges crossing the River Mersey in the town of Warrington, England. The current structure is the sixth to stand in this location and was constructed 1909–15 by Alfred Thorne & Sons.[1] For centuries Warrington Bridge provided the lowest crossing of the Mersey and thus was of strategic and commercial importance. It is located to the south of the present town centre and linked to it via Bridge Street.
