York-Bay-Yonge exit on eastbound Gardiner Expressway closed permanently

Just when you thought traffic in the city couldn’t get any worse.

The heavily-used eastbound Gardiner Expressway ramp to York, Bay and Yonge Streets closed early Monday morning.

The ramp is set to be replaced by a shorter one from the eastbound Gardiner to Lower Simcoe Street.

As part of the project, Harbour Street will also be widened from three to four lanes from Lower Simcoe to Bay Street in order to help with traffic flow and to improve pedestrian and cycling access to the waterfront.

“This is a big undertaking. It will be disruptive. There is no doubt,” Toronto city councillor and public works chair Jaye Robinson said at a press conference earlier in the month.

“But the Gardiner is crumbling and we need to address it.”

There will be periodic daytime closures of the centre lane of Harbour Street from Lower Simcoe Street to Bay Street between May 1 and June 15 from 9:30 a.m. to 3:30 p.m.

During construction, traffic signal timing on alternative routes will be adjusted to minimize congestion, and motorists will have access to downtown by exiting the eastbound Gardiner at the Jameson Avenue, Spadina Avenue and Jarvis Street ramps. Motorists will also be able to access the eastbound Lakeshore Boulevard from the eastbound Gardiner ramp at Spadina.

The project is set to run until January 2018, and is expected to cost about $30 million.

Work will take place Monday through Saturday from 7 a.m. to 7 p.m. and sometimes overnight, pending city approval.

This is just one of the many construction projects the city has announced it will be undertaking, as Robinson said $700 million is being invested this year to fix 100-year-old watermains, crumbling bridges, roadways and streetcar tracks.

Lane reductions are already in place on Wellington Street from Church Street to York Street. Work is expected to be complete by September.
