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.


  • September 19 – We are working at 5:00 a.m. on Saturday, September 20 in the rail corridor between Joe Shuster Way and north of the Queen Street West Bridge.
  • September 9 – Beginning Friday, September 19, (subject to change) Douro St. will be closed to traffic between Crawford St. and Strachan Ave. for 2 to 3 weeks. Local traffic will be accepted but there will be no access to Strachan Ave. This work is to reconnect utilities that were relocated as part of the Strachan Avenue Overpass construction. Sidewalk and roadway construction will also be completed.
  • July 31 – In July, work continued on the middle retaining wall, the permanent Strachan Ave. bridge and track and grading work between the King St. W. and Queen St. W. rail bridges. What to expect in the coming months:
    • Re-profiling Strachan Ave. to open the bridge. Expect lots of temporary conditions along Strachan Ave. The bridge is expected to be partially open in August.
    • Several large drainage ditches are being built between the King St. W. and Queen S. W. rail bridges.
  • July 23 – This summer, expect changing traffic patterns and delays along Strachan Avenue and side streets.
  • 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

Douro Street Retaining Wall Beautification

The Bathurst Street to King Street West Community Advisory Committee looked at options to deter graffiti and beautify the existing retaining wall on Douro Street. As this wall has already been built, there is some urgency in improving its appearance and preventing more graffiti.

We also reached out to the larger community and received feedback from over 100 people for the design options for the Douro Street Retaining Wall Beautification.

We used a phased approach, with the beautification of the wall as phase 1, and the beautification of the boulevard as phase 2. This allows us to begin implementing the recommendations for phase 1 immediately. Phase 2 will be implemented after discussion with the City as they own this parcel of land. GO Transit has considered the recommendations provided for Phase 1 and we will implement all the recommendations made by the committee. To learn more, please view the document below.

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).
