Rehabilitation work to begin on Gardiner Expressway between Dufferin and Strachan

Rehabilitation work to begin on Gardiner Expressway between Dufferin and Strachan

TORONTO – The next phase of the City of Toronto’s Gardiner Expressway Strategic Rehabilitation Plan will begin next week.

Lane restrictions will begin on Monday (March 25) on the Gardiner Expressway between Dufferin Street and Strachan Avenue. The city reports the more than 60-year-old route is reaching its end of service life due to the effects of age, heavy daily use, weather and salt.

Toronto City Council approved the Gardiner Expressway Strategic Rehabilitation Plan, which divides all the needed repair work into six sections.

Preparatory work on this portion began in November 2023 and construction is expected to continue until mid-2027.

Details of this work include replacing 700 metres of the elevated bridge surface on the expressway; rehabilitating the structures underneath that support the elevated expressway; and adding a new traffic management system and streetlights.

Other work, including girder removal and replacement, shifting of traffic barriers between work stages and the delivery of materials, may be required at night.

The rehabilitation of this stretch is complex as the roadway is elevated, very narrow and busy, indicates a city release.

Drivers may not see workers along the Gardiner during road closures, as much of the work will be done from underneath.

From May to the end of July 2026, the expressway will be fully open with no lane restrictions to accommodate the increased traffic anticipated during the FIFA World Cup.

“This construction is urgently needed to keep traffic flowing and keep our communities connected,” said Mayor Olivia Chow in a statement. “The city is committed to completing this section of work to ensure a state of good repair for generations to come as we focus on getting Toronto back on track.”
