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. 

Updates

  • January 26, 2015 – We will be reconstructing the sidewalk at the northwest corner of Strachan Avenue and East Liberty Street. This work will reconfigure the slope of the sidewalk. Sidewalk reconstruction is continuing into March.
  • January 9, 2015 – Starting Monday, January 12, until the end of the month, we will be welding track in the lowered rail corridor between 7 p.m. and 5 a.m. This work can only be completed at night when the trains are not operating. This work is to remove track joints creating continuously welded rail which reduces noise from train wheels crossing over the joints.

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).
