Garrison Crossing
History
The project was first initiated in the early 2000s and was canceled for cost reasons. In 2014, the council approved the project procured as a Design-Build project directed by CreateTO, the City of Toronto's real estate and development corporation, with a budget of $19.7-million. The project was awarded to Dufferin Construction with a stainless-steel bridge project, the first of its kind in Canada. The project was completed in October 2019.
Design
The two bridges are constructed of a single stainless-steel arch rib of triangular shape utilizing standard hot-rolled stainless-steel plates that suspend the deck by a network arrangement of stainless-steel hangers. The arch ribs are titled outwards in opposite direction. The deck is a trapezoidal stainless-steel box girder with ribs on one side. The steel box is connected to a top concrete slab that uses stainless-steel reinforcement.
The north bridge is a 52 m long through arch bridge, while the south bridge is a one-span arch connected to a V-shape pier on the south end to accommodate the 5 m elevation difference between the two ends. The South Bridge landing includes a 58 m long structural concrete ramp on the west side terminating in a cantilevered lookout on the east side.
Construction
Construction started in August 2016. The two bridge structures were hoisted into place by a 660-ton crawler crane in the summer and fall of 2018 and were completed in October 2019.
