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.

Updates

  • May 10 – Strachan Avenue Overpass: A new stage of construction begins.
  • April 29 – Work continues on the portion of the walls that will support the new Strachan Avenue bridge. As shown by the hard-to-miss drill rig positioned in the middle of Strachan Avenue, the drilling of caissons for the middle wall and bridge foundations has begun. South wall construction west of Strachan Avenue also began this month with the installation of piles to form a guide wall. Planks were installed on two tracks to allow construction vehicles to cross over the tracks. The relocated signal bridge near the west end of the project has now been installed. Installation of the architectural strut covers continues. With construction shifting to the south half of the corridor, a new access (e.g. entranceway to the corridor) at Joe Shuster Way and Dufferin Street is being built to allow construction vehicles to enter and exit the corridor at this location.
  • April 16 – We will begin preparing an access to allow construction vehicles to enter the rail corridor. Access is for the Strachan Avenue Overpass construction project. The access will include a vehicle driveway with a gate.
  • March 14 – Starting March 18 until April 30 (with the possibility of an extension), eight street level parking spots and adjacent sidewalk on Western Battery Road will be closed. The impacted parking spots will be marked with traffic cones in advance. We are preparing to start construction of the south retaining wall of the rail corridor, west of Strachan Avenue.

What we are doing

  • Construction of the Siphon Tunnel
    • Currently, a three-metre diameter storm sewer runs directly underneath Strachan Avenue and needs to be located below the future lowered rail corridor
    • Work on the vertical shafts for the new sewer (siphon tunnel) is completed at the southeast corner of Strachan Avenue and Fleet Street and the southwest corner of Strachan Avenue and Douro Street
    • The tunnel boring machine for the sewer (siphon) tunnel completed the 540-metre tunnel that runs from Fleet Street to Douro Street
    • Tunnel construction was completed in fall 2012
  • Construction of the Retaining Walls
    • Three retaining walls will be required to support the lowered rail corridor: a north, centre and south wall
    • Construction is nearing completion on the north and centre walls
  • Temporary realignment of Strachan Avenue
    • Strachan Avenue has been diverted to the west to facilitate construction of the lowered rail corridor
  • Excavation of the Rail Corridor is Underway
    • The corridor is being excavated in two phases to maintain railway operations
    • The north section of the corridor is being excavated first with all rail service being shifted to the south tracks

How this will affect you

  • Temporary realignment of Strachan Avenue in 2012/13
  • There is a temporary loss of parking spots on the south side of Douro Street near Strachan Avenue

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).
