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

  • August 20 – The final step of the watermain work on Church St. will take place from 7 a.m. August 25 to 7 a.m. August 27. Weather permitting, this work may be extended to finish at 7 p.m. August 28 These pulls must be completed in one continuous motion and are anticipated to take 48 hours. During the 48-hour pipe pull, access to Cross St. from Church St. will be closed.
  • July 31 – Final sidewalk restoration is almost complete on the south side of Church St., between Rosemount Ave and George St. During the weekend of July 26 to 27, we shifted the rail tracks between Weston GO Station and the Weston Tunnel project. This provided additional space to complete the southernmost tunnel structure. Excavation at John St. is expected to be completed this month, with the tunnel floor and walls being poured this summer. On July 25, we completed the strut installation north of Church Street. To date, 100 per cent of the structural steel struts are in place. Concrete pours are ongoing to form the tunnel roof that runs between King St. and Church St. and will be completed this summer. What to expect in the coming months:
    • Continuous overnight work, requiring the full closure of King St. between Rosemount Ave. and George St., is scheduled to occur from 7:00 p.m. Friday, August 8 to 12:01 a.m. Monday, August 11. This closure is necessary for the installation of a City of Toronto storm maintenance hole and road regarding.
    • Final sidewalk restoration on the north and south sides of King St., between the railway corridor and George St., will take place from August 11 to 14.
    • Church St. will remain closed at Rosemount Ave. until late summer for the City of Toronto watermain relocation.
  • July 28 – Sidewalk restoration work will take place on Church and King Streets on the following dates: August 11 to 14.
  • 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.
  • 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.

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).
