The City of Toronto is moving forward with a new implementation strategy to rehabilitate the Gardiner Expressway. This new approach will enable the city to proceed quickly in order to deal with the urgent rehabilitation needs of the expressway.
The Gardiner Expressway was built between 1955 and 1966. The effects of weathering, salt and increased traffic loads have taken their toll on the roadway and the concrete deck of the elevated section is approaching the end of its service life.
The new approach will feature a series of multiple contracts through an accelerated design-bid-build delivery model. This will enable the work to be done as quickly as possible to minimize traffic disruptions while the work is performed.
The City has successfully completed several projects on the expressway on time and on budget using this approach. The most recent example of this was the west deck project from Exhibition Place to Bathurst Street, which was completed a full six months ahead of schedule.
The City has reviewed the expressway and determined that the rehabilitation work will be initiated on the elevated section of the expressway from Jarvis Street to Cherry Street.
The City will take on the work east of Cherry Street after an engineering consultant reviews the best strategies for incorporating a series of other projects in this area. In doing so, opportunities to coordinate all of the work in this area can be used.
The City originally considered delivering the work through a public-private partnership, however, due to cost increases, this plan was not recommended by staff.
Using the City’s new implementation plan, the cost of the rehabilitation work on the expressway for the next ten years is $2.3 billion. This funding is part of Transportation Services approved 10-Year Capital plan. This provides the necessary funding for most of the rehabilitation needs of the Gardiner Expressway from Highway 427 to the Don Valley Parkway, including implementing the Gardiner East Hybrid Design Alternative #3.
