The City of Toronto is taking a proactive approach to managing the rehabilitation of the Gardiner to keep the roadway in safe and operable condition. City staff have evaluated the procurement options and are recommending an AFP approach to rehabilitate the Gardiner in the most efficient way for Toronto residents and businesses. The proposed plan addresses the rehabilitation of the expressway, extending from Highway 427 to the eastern limit at Logan Avenue, including the 11-kilometre at-grade section from Highway 427 to Dufferin Street with its 32 bridges and structures, and the seven-kilometre elevated section from Dufferin Street to Logan Avenue with 335 spans. It incorporates the change of scope for the rehabilitation of the Gardiner Expressway east of Jarvis Street based on the future outcome of the environmental assessment. In 2021, the City of Toronto achieved a significant construction milestone by completing the rehabilitation of the elevated section of the Gardiner Expressway between Jarvis and Cherry Streets with traffic resuming on all lanes in mid-April. To complete this work faster and to be less disruptive to the public, the City used an innovative construction technique called Accelerated Bridge Construction to replace concrete deck and steel girder sections on the elevated portion of the Expressway with prefabricated concrete deck panels. During this project, the largest of its scale in North America, sections of the Expressway were saw cut, hoisted out of place and transported elsewhere to separate and recycle the concrete deck and steel girders.
