The MAADI Group engineering firm, Montréal, Québec, has installed a new aluminum arched pony-truss bridge as part of the TD Place Project, in Ottawa, Ontario, Canada. The strong, lightweight aluminum 30-meter-long (98 ft 5 in) bridge is designed specifically for pedestrians and light vehicles, and is constructed with welded, high-strength aluminum alloy that is durable and maintenance-free. The bridge design features a Warren-type truss structure as the main girder, extruded aluminum pony-truss truss framework, aluminum side guardrails and fencing, and IPE hardwood decking that resists slipping and skidding. The new pedestrian bridge is the gateway entrance to the TD Place Stadium complex. TD Place is home to the new CFL football club team the Ottawa RedBlacks, the North American Soccer League’s Ottawa Fury FC team and the Ottawa 67’s OHL hockey team.
The bridge has a clear width of 1883mm (6ft, 2in) between its handrails, which are located 900mm (3ft) above the deck. Stylish picket aluminum fencing is 1070mm (42in) in height above the deck level, running vertically along the bridge sides from floor decking upward, spaced closely together as a child safety feature, as required by the Ontario Building Code. Stainless steel bridge anchors with 25mm (1in) threaded rods, fasteners, rivets, and screws secure the bridge onto its abutments.
The TD Place Bridge has IPE hardwood decking planks that are 25mm (1in) thick. The bridge’s dead load including decking is 7 925 kilograms (17,435 pounds). The pedestrian bridge’s aluminum structural components: chords, diagonals, transversals, stringers, handrails, aluminum fencing, and transition plates weigh 5 959 kilograms (13,110 lb) without decking, and 7 925 kilograms (17,435 pounds) with decking. MAADI Engineers designed thermal expansion joints at the bridge ends to enable the bridge to expand and contract up to 50.4mm (2in), allowing for a temperature gradient of 70 degrees, between -35°C and 35°C (-31°F to 95°F). The typical seasonal Stadium temperatures will vary from -15°C to 26°C (5°F to 79°F).
The bridge’s camber clears a 5M (16ft, 5in) height by 6M (19ft, 8in) width double line roadway used for maintenance and vehicles that enter the stadium field for parades and special events. The bridge’s walking surface has a mean grade of 8 percent, varying from end to end to accommodate the vertical clearance needed for the roadway path below.
The aluminum bridge’s arched-rail design blends with its natural surroundings and provides durable functionality. The bridge will handle light maintenance vehicles that, when fully loaded, weigh approximately 1 000kg (2,240 lb) each. The TD Place Bridge was installed by 4 workmen and one crane operator in just 6 hours using a 110-ton capacity crane.
