The intersection of Spadina Avenue and Dundas Street West is fully closed in all directions for two weeks for TTC construction.
The City of Toronto and the TTC started major construction on watermains, streetcar tracks, roads, and sidewalks in the area on Monday.
During Phase 2 of the project — from July 28 to Aug. 11 — the TTC will upgrade its switches and tracks as part of ongoing maintenance.
“What the TTC needs to do is pull out all of that track and [the] switches and rebuild the intersection with new track,” TTC spokesman Brad Ross said earlier.
“The last time that was done was 1996.”
During the two-week closure, motorists heading east on Dundas approaching Spadina will be diverted at Bathurst Street, while westbound traffic on Dundas will be rerouted at University Avenue. Drivers heading north on Spadina approaching Dundas will be forced to detour at Queen Street West, while southbound traffic on Spadina will be diverted at College Street.
City officials said access to local businesses will be maintained during the two-week full closure.
Since July 14, the area has been partially closed off to replace a watermain.
At the same time, the TTC will be retrofitting the streetcar platform at Spadina Station to accommodate its new low-floor streetcars.
Phase 3 is scheduled to begin on Aug. 11. It will include a partial closure of the intersection.
The 505 Dundas and 510 Spadina streetcars are already on diversion in the area. Click here for a list of the service adjustments.
