The section of the Gardiner Expressway between Jarvis Street and Cherry Street is nearing the end of its service life and is the number one priority for rehabilitation in the Gardiner Expressway Strategic Rehabilitation Plan.

The City of Toronto is renewing this section of the expressway in a way that’s faster and less disruptive than ever done before.

This work is using an innovative construction method called Accelerated Bridge Construction, which can reduce the construction time by approximately 40 per cent and minimize the impact on the travelling public as well as reduce noise and dust impacts.

Image depicting the 2019 construction work that will take place on the Gardiner Expressway between Jarvis Street and Cherry Street. Graphic indicates the work phase order. A large Number 1 stands by a sign of westbound Yonge, Bay, York Street off-ramp which will be rehabilitated first this summer. The Number 2 on the graphic demonstrates the second work phase where two lanes of traffic open on the south side of the expressway. On the north side of the expressway, the graphic shows two sets of cranes removing and replacing sections of the expressway deck. Below the expressway on Lake Shore Boulevard, the graphic demonstrates rolling lane closures underneath where sections are being removed with one lane of traffic flowing through. The Number 3 on the graphic indicates the third phase of work, the westbound Sherbourne off-ramp will be closed for replacement.

Work Phase 2019 Construction Activity Details Timeline
1 Yonge-Bay-York Westbound Off-Ramp Rehabilitation
  • Yonge-Bay-York westbound off-ramp will be fully closed for extensive repairs (known as rehabilitation)
  • Consider other westbound off-ramps such as Sherbourne Street or Spadina Avenue
  • To access downtown, consider alternate routes such as exit the DVP onto Richmond Street, exit the Gardiner at Jarvis Street and enter from the east, exit the Gardiner at Spadina Avenue or travel on Lake Shore Boulevard westbound to access Yonge, Bay or York Streets
  • See below accordion for full details
10 p.m. on July 15 to September 16, 2019
2 Gardiner Expressway Deck Replacement – North Side between Jarvis Street & Cherry Street
  • This phase will begin once the Yonge-Bay-York westbound off-ramp is complete
  • The north side of the Gardiner Expressway between Jarvis Street and Cherry Street will be fully closed for full replacement of the concrete deck and steel girders
  • Two lanes of eastbound and westbound traffic will remain open on the south side of the expressway
  • There will be 15 minute rolling closures on the westbound lanes of Lake Shore Boulevard East during off-peak hours (between 10 a.m. to 3 p.m. and 10 p.m. to 5 a.m.) so crews can safely remove and replace sections of the expressway above
  • This phase is using an innovative technique called Accelerated Bridge Construction which can reduce construction time by up to 40 per cent
  • This technique removes sections of the existing expressway deck and replaces it with custom built pre-fabricated sections
TBC
3 Sherbourne Street Westbound Off-Ramp Replacement
  • Sherbourne Street westbound off-ramp will be fully closed for replacement
  • During construction, only one ramp will be closed at a time and this work will begin after the Yonge-Bay-York westbound off-ramp is complete
  • Consider alternate off-ramps such as Yonge-Bay-York or Spadina Avenue
  • This phase is using Accelerated Bridge Construction which can reduce construction time by up to 40 per cent

Timelines and more details of the work planned for 2019 will be updated once construction schedules are confirmed. Construction Notices will be updated and issued before the construction work phases begin to provide advance notice.

Work Phase 2020 Construction Activity Details
4 Ramp Replacement – Eastbound On-Ramp at Jarvis Street
  • The eastbound on-ramp at Jarvis Street will be fully closed for replacement
  • All other ramps will remain open
5 Gardiner Expressway Deck Replacement – South Side between Jarvis Street & Cherry Street
  • The south side of the Gardiner Expressway between Jarvis Street and Cherry Street will be fully closed for full replacement of the concrete deck and steel girders
  • This work will take place at the same time as the replacement of the eastbound on-ramp at Jarvis Street
  • Two lanes of eastbound and westbound traffic will remain open on the north side of the expressway
  • There will be 15 minute rolling closures on the eastbound lanes of Lake Shore Boulevard East during off-peak hours (between 10 a.m. to 3 p.m. and 10 p.m. to 5 a.m.) so crews can safely remove and replace sections of the expressway above
  • The deck and ramp replacement is using an innovative technique called Accelerated Bridge Construction which can reduce construction time by up to 40 per cent
  • This technique removes sections of the existing expressway deck or ramp and replaces it with custom built pre-fabricated sections

Timelines and more details of the work planned for 2020 will be updated once construction schedules are confirmed.

About Accelerated Bridge Construction

This project is using an accelerated bridge construction method that can reduce the construction time by as much as 40 per cent compared to traditional methods. This will be the first time this method has ever been used in Toronto and at this scale in an urban centre.

This method involves building sections (i.e. panels) of the new expressway off-site in a climate controlled facility, or fabrication site, and then transferring the sections into place on the Expressway where existing sections have been removed.

Faster, Less Disruptive & Higher Quality Construction

Using this accelerated method, this project – which spans a 1.5km work zone – will be completed in less than two years. In comparison, the work on the Gardiner West deck rehabilitation from Bathurst Street to Strachan Avenue used traditional methods and took two and a half years to complete with a work zone half the size.

Unlike traditional methods, accelerated bridge construction does not require regular jack-hammering and therefore reduces the impact of noise and dust. As well, since the components are made in a quality and climate controlled facility, the final construction product is typically of a better quality.

Fabrication Site

You may have noticed heavy machinery, site trailers and large tent structures on lands by Lakeshore Blvd East near Cherry Street. This is the City’s fabrication site and staging area for the Gardiner Expressway Strategic Rehabilitation from Jarvis to Cherry Street.

The large tent structures is the fabrication site where crews will build 413 panels that will replace the expressway deck between Jarvis to Cherry Streets and the westbound off-ramp at Sherbourne Street and the eastbound on-ramp at Jarvis Street. Each panel is unique to the design of the expressway and ramps.
