R.V. Anderson Associates Limited was retained by the City of Toronto and the Toronto and Region Conservation Authority to carry out structural design services, construction inspection, and construction advisory services. The project includes two pedestrian bridges designed to cross the east branch of the Don River.
The bridge Is located immediately adjacent to an active CN rail line and the Don Valley Parkway which required the closure of a lane, traffic control and the incorporation of CN safety protocols.
The Phase 2 bridge is three meters wide and spans 34 meters. This truss bridge was fabricated by Resource Industrial Group in two sections, assembled on site and hoisted by the crane onto concrete bridge abutments. The bridge consists of structural weathering steel members, western red cedar wood cladding and rub rails.
The bridge footings were designed to minimize excavation and environmental disturbance by incorporating helical pier foundation system. A total of sixteen helical piers were installed approximately 11 meters into the ground to support the concrete abutment, self weight of the bridge, and design live loads.
