The City is set to undertake critical repairs on five bridges along or over the Gardiner Expressway, with construction scheduled to begin in spring 2025. This work is part of the planned rehabilitation for Section 3 of the Gardiner Expressway, which spans from Highway 427 to the Humber River. While full rehabilitation for this section is currently scheduled to start as soon as 2027, condition assessments have identified these five bridges as requiring repairs in advance of 2027.

The F.G. Gardiner Expressway has been in service for more than 60 years and with the effects of weathering, salt and increasing traffic loads, it is approaching the end of its original design life. In order to maintain a safe roadway and ensure a state of good repair, a Strategic Rehabilitation Plan consisting of six complex projects was adopted by Toronto City Council in December 2016. Section 1 construction work was completed in 2021. Section 2 work is currently in progress, with expected completion by April 2026.
Gardiner Section 3 runs from Highway 427 to the Humber River and will reconstruct 6.5 km of at-grade expressway, including the rehabilitation of 11 bridges where the Gardiner passes over roads or creeks and four bridges that go over the Gardiner. Planning for the full rehabilitation program for this section of the project is underway to determine scope, phasing, staging, and the construction schedule.
