The Five Mile Bridge is Illinois' first and one of America's few timber arch vehicular bridges. The three-hinged arch features an unusually long span and is designed to accommodate both vertical and horizontal curves. Timber was selected to complement the historic site when a deteriorated steel pony truss bridge crossing the Illinois & Michigan Canal National Heritage Corridor required replacement. Design specifications included: HS-20 design live load; 126-ft clear span; 35-ft wide timber deck with water-proof membrane; and horizontal and vertical curve geometry.
