Overhead Infrastructure Removal and Reinstatement at the St Clair Avenue West Rail Bridge

Effective September 6, 2026 to October 3, 2026

What we are doing and why

TTC streetcar service is suspended on St. Clair Avenue West between Weston Road and Old Weston Road to accommodate the City’s St. Clair-Old Weston SmartTrack Station project and Metrolinx’s demolition of the St. Clair Avenue West bridge. Replacement bus service is operating through the area.

To support this construction, the TTC is reinstall the overhead streetcar infrastructure on St. Clair Avenue West between Weston Road and Old Weston Road.

Streetcar service is expected to resume Saturday, October 3, 2026.

Equipment

TTC overhead trucks with hydraulic equipment will be used to carry out this work. While efforts will be made by the crew to keep noise to a minimum, beeping sounds when the trucks are backing up will be audible. Equipment lights may also be noticeable.
