Weston Tunnel

The GO rail corridor will be lowered from Lawrence Avenue to Weston Road, with a covered portion between King Street and Church Street. Because the rail corridor will not yet have descended low enough to keep the road level, John Street will be closed to vehicular traffic; a pedestrian bridge will be built over the GO tracks to keep John Street open to pedestrians. The corridor will ascend north of Church Street, returning to ground level before the Weston Road bridge.

The Tunnel Cover, between King Street and Church Street, will be at the same grade as the St. John the Evangelist Church and School property lines. With public access from Church or King Street, the tunnel cover is being designed to accommodate a green space and/or recreational public use to be maintained by a third party, such as the City of Toronto or the Toronto Catholic District School Board.

Updates

  • July 28 – Beginning at 7 p.m. on August 8 to 12:01 a.m. on August 11, King Street will be closed at the rail corridor for the installation of City of Toronto maintenance chambers and road re-grading and re-profiling.
  • June 27 – John St. access across the rail corridor was closed permanently on April 28. The water main running beneath the rail corridor has been rerouted and excavation has started. Installation of structural steel and pouring concrete to form the tunnel roof that runs between King St. and Church St. is underway and will be completed this summer. The John St. Pedestrian Bridge is expected to be completed by the end of the year. What to expect in the coming months:
    • Work continues to excavate and lower the rail corridor at John St. to prepare for the construction of the John St. Pedestrian Bridge.
    • Church St. will remain closed at Rosemount Ave. until late summer for City of Toronto watermain relocation.
    • Strut installation north of Church St. took place from June 23- 27, and the second set will take place from July 7-18.
  • May 9 – Periodically over the next three months, we will pour concrete to form the tunnel walls and cover from the parking lot at St. John the Evangelist school. Weather permitting, these pours will occur up to two times per week between the hours of 10 a.m. to 3 p.m. to minimize disruption to student drop-off/pick-up on George Street.
  • October 28 –  Work hours will be from 7:00 a.m. to 11:00 p.m., Monday to Saturday for six months until spring 2014.

Project Schedule

  • Excavation start: fall 2012
  • Construction complete: end of 2014

What we are doing

  •  GO rail corridor will be lowered from Lawrence Avenue to Weston Road, with a covered portion between King Street and Church Street
  • John Street will be closed to vehicular traffic
    • a pedestrian bridge will be built over the GO tracks to keep John Street open to pedestrians

How this will affect you

  • Temporary road closures of Church Street and King Street in 2012 or 2013 during tunnel construction
    • Closures will impact only one road at a time
  • Working with property owners for temporary easements to gain construction access

Noise and Vibration

Noise and vibration monitors have been set up along the Weston Tunnel 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).
