The intersection of Spadina Avenue and Dundas Street West will be partially closed to traffic for the next two weeks for streetcar track and platform upgrades to make way for the TTC's fleet of new low-floor streetcars.
Traffic will be down to one lane in each direction during the partial closure, which will last until July 28.
After that, the traffic situation will get worse, as the intersection will be shut down entirely for two weeks. The full closure will occur between July 28 and Aug. 11.
Eastbound traffic on Dundas approaching Spadina will be detoured at Bathurst Street, while westbound traffic on Dundas approaching Spadina will be diverted at University Avenue.
Traffic on northbound Spadina will be detoured at Queen Street West. Southbound motorists will be forced off Spadina at College Street.
The city is suggesting motorists use College or Queen streets as alternate routes for east-west traffic, and Bathurst or University for north-south traffic.
