The City of Toronto has studied various options for reconfiguration of the York/Bay/Yonge interchange on the Gardiner Expressway to improve the public realm and access to park space while maintaining adequate traffic capacity. Ramps studied included the off-ramp from the Eastbound Expressway to York, Bay and Yonge Streets, and the on-ramp from Bay Street to the Eastbound Expressway. The study was completed in Spring, 2013.
The recommended solution is to:
- Rremove the existing long elevated structure to Bay Street and loop ramp at York Street and replace them with a shorter direct ramp to Harbour Street at Lower Simcoe Street
- Reconfigure Harbour Street four eastbound lanes between Lower Simcoe Street and Bay Street
An illustration of the recommended solution is shown below:
The study area is bounded by Bathurst Street, King Street, Jarvis Street/Lower Jarvis Street, and Queens Quay.
The traffic impact study area is bounded by York Street, Front Street West, Yonge Street and Queens Quay West. Both study areas are shown on the key map below.
