Strachan Avenue Overpass

The Strachan Avenue Overpass is one of the grade separations for the Georgetown South Project. Formerly a level crossing, Strachan Avenue has been raised and the rail corridor lowered several metres. In October 2013, trains began operating on new tracks in a new north lowered corridor and the level crossing was removed. A year later, the new Strachan Avenue bridge fully opened providing two lanes for vehicles, two lanes for cyclist and two sidewalks over the rail corridor. 


  • May 19, 2015 – We will be restoring the intersection at Strachan Ave. and East Liberty St. Starting Wednesday, May 20 at 7 a.m. until Friday, May 22 at approximately 7 a.m. the southwest sidewalk on East Liberty St. will be temporarily closed along with the eastbound traffic lane. The eastbound traffic lane will be directed into the westbound lane. Work will take place continuously during this period of time including overnight. Work will then continue to restore the intersection until the end of June. Hours of work will be 7 a.m. to 7 p.m., including weekends. Overnight work may also be required, if necessary.

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).
