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.
|Work Phase||2019 Construction Activity||Details||Timeline|
|1||Yonge-Bay-York Streets Westbound Off-Ramp Rehabilitation||
See below accordion for full details.
|Complete 10 p.m. on July 15 to September 22, 2019|
|2||Lower Sherbourne / Lower Jarvis Streets Westbound Off-Ramp Replacement||
||11:59 p.m. on October 4 to April 18, 2020|
|3||Gardiner Expressway Deck Replacement – North Side between Jarvis Street & Cherry Street||
This technique removes sections of the existing expressway deck and replaces it with custom built pre-fabricated sections.
|5 a.m. on October 14 to late-summer 2020|
|Work Phase||2020 Construction Activity||Details|
|4||Ramp Replacement – Eastbound On-Ramp at Jarvis Street||
All other ramps will remain open.
|5||Gardiner Expressway Deck Replacement – South Side between Jarvis Street & Cherry Street||
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.
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.
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.
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 nearly 400 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.
