The Regional Municipality of Niagara has issued a tender to replace Burgoyne Bridge. The bridge carries Regional Road 81 over the Twelve Mile Creek and Highway 406.
The new 333 m long bridge is a 7-span structure that consists of two independent continuous steel box girders with a reinforced concrete deck. Each girder carries a 9 m wide platform that accommodates a 2.4 m sidewalk, a 3.5 m traffic lane, a 1.5 m bicycle-lane, a 0.5 m shoulder and two 0.5 m external barriers. The main span, over the Twelve Mile Creek and Highway 406, is 125 m long and is suspended by a steel truss tied-arch. At the main span the two girders are linked by steel transverse beams. The arch and the deck are connected via 23 pairs of hangers. The horizontal component of the axial force of the arch is not transfer to the deck but to a set of horizontal cables anchored to the piers at the arch’s ends. The rest of the spans vary between 20 and 42 m and rest on reinforced concrete piers.
