Last summer, City Council voted to keep the Gardiner Expressway as a continuous elevated freeway through downtown, with direct ramps to the Don Valley Parkway, eschewing proposals to tear down or
bury Toronto’s favourite eyesore.
Now council is being asked to pick a particular variation of the Gardiner reconstruction known as Hybrid 3, so the Environmental Assessment can move ahead, since the Gardiner’s eastern surface deck, in its current state, is only expected to last until 2020.
The hybrid option championed by Mayor John Tory has been considered in more detail over the last few months, producing three possible variations. Hybrid 1 will provide tighter ramps in the Keating Channel Precinct but stick close to the Gardiner’s existing route. Hybrid 2 moves the expressway further north to create more space between Lake Ontario and the expressway. Hybrid 3, which also aligns the Gardiner further north, would also widen the rail bridge underpass. At a stakeholder advisory committee and a recent public open house, Hybrid 3 was the best received option.
“Hybrid 3 supports the city-building potential of the Keating Channel Precinct, a planned mixed-use waterfront community that will evolve as the gateway to a revitalized Port Lands and accessible Keating Channel. This would be accomplished by rebuilding the elevated portion of the Gardiner as far north from the Keating Channel as is feasible,” states the staff report. “Implementation of the design would provide unencumbered access to a planned waterfront promenade, better conditions for creating future high-quality park, open space and pedestrian-friendly environments and more valuable development blocks. By comparison, Hybrid 2 would achieve some but not all of the urban design benefits described above. Hybrid 1 would result in a neighbourhood flanked on both sides by rail and expressway infrastructure, bisected by Lake Shore Boulevard and separated from the water's edge by an elevated expressway with associated on/off ramps.”
The staff report, which will be considered by the Public Works and Infrastructure Committee on February 29, and by council on March 30, says Hybrid 3 would have “the least physical and visual impact on the planned revitalization of the Don River. Implementation of this design would have the least impact on future sediment management activities, as well as the least amount of physical infrastructure, including structural piers, to be located within the river itself (with details to be confirmed at the detailed design stage).”
