TTC Bloor-Danforth line closed as viaduct work begins

The Bloor-Danforth subway line is closed between Pape and St. George Stations this weekend as construction work begins on the Bloor Street Viaduct.

Shuttle buses are operating between the stations.

On Sunday, the road over the bridge is set to close, likely complicating traffic flow in the Danforth area and making alternate Don Valley crossings busier than normal.
