Strachan Avenue Overpass

The Strachan Avenue Overpass is one of the grade separations for the Georgetown South Project. Strachan Avenue will be raised by, at most, 2 metres to pass over the rail corridor. In turn, the rail corridor will be lowered from Bathurst Street to King Street West, the lowest point of up to 8 metres below at Strachan Avenue. The new overpass will also accommodate bicycle lanes and sidewalks. The first trains began using the corridor on Monday, October 21, 2013. On October 11, 2014 the Strachan Avenue Bridge fully opened. Traffic is now flowing along freely in two traffic lanes with two cycling lanes on the new bridge.


  • November 14 – As we approach the end of the Strachan Avenue Overpass work, we are in the final stretch of installing the last sections of track to complete the expansion of the rail corridor to increase commuter train service. Conduit Work: There may be some intermittent overnight work until the end of November (weather permitting). Track Shift: For three weekends, November 22/23, December 6/7 and December 13/14 (may be rescheduled due to weather), we will be working continuously beginning Friday at 7 p.m. to Monday before 6 a.m. to shift and install new tracks in the south corridor between Bathurst St. and north of Queen. St. W.
  • May 23 – Starting Saturday, May, 24 and each following Saturday until the end of the project, work hours will be 7:00 a.m. to 7:00 p.m. The extended work hours on Saturdays will allow us to continue focusing on completing the new bridge over Strachan Ave. and return the alignment of the road to its original position as soon as possible.

Project Schedule

  • Phase 1 construction started: winter 2011
  • Phase 1 construction completed: spring 2012
  • Phase 2 construction started: summer 2011
  • Phase 2 construction complete: end of 2014

What we are doing

  • Utility relocation
    • Construction of a siphon tunnel, utility tunnel, and relocation of all utilities
  • Construction of three retaining walls to support the lowered rail corridor: a north, centre and south wall
  • Excavation of the rail corridor
    • The corridor is being excavated in two phases to maintain railway operations
    • The north section of the corridor was excavated first with all rail service being shifted to the south tracks
    • After the north corridor excavation was complete, train operations shifted to this lowered corridor (project milestone), and excavation began in the south corridor
  • Installation of struts and the permanent Strachan Avenue bridge

How this will affect you

  • Temporary realignment of Strachan Avenue
  • There is a temporary loss of parking spots (south side of Douro Street near Strachan Avenue, Western Battery Road)
  • Occasional lane restrictions
  • Removal of the level crossing

Noise and Vibration

Noise and vibration monitors have been set up along the Strachan Avenue Overpass project area to monitor any noise and vibration generated by the construction. This data will be posted on a weekly basis.

The following graph displays 1-hour averaged noise levels measured in decibels (dbA).
