News Release
July 8, 2021

The City of Toronto will perform annual maintenance and improvement activities on the Gardiner Expressway this weekend. A full closure of the expressway, from the Don Valley Parkway/Carlaw Avenue to Highway 427/Queen Elizabeth Way, is expected to take place from Friday, July 9 at 11 p.m. until Monday, July 12 at 5 a.m.

This closure was rescheduled from the weekend of June 25 to 28 due to inclement weather, which would have prevented a significant amount of milling and paving work from being completed.

The full closure of the Gardiner Expressway for one weekend each year is an important, efficient and safe way that City road crews, engineers and other stakeholders can make improvements and keep the throughway in the best state of good-repair. Performing this highly coordinated work over a 54-hour window helps to keep the thousands of daily drivers that use the Gardiner Expressway on their way.

City staff have readied detailed traffic plans to help manage traffic congestion over the weekend. Signage to notify drivers was put in place and activated in advance of the closure weekend and signals around the closure will be timed and actively managed throughout the weekend. In addition, information has been posted on the City social accounts and website.

Examples of maintenance work that will be performed this weekend include:

  • Milling and paving of 15 km of roadway including more than 11,000 tonnes of asphalt
  • line marking
  • overhead and ground sign inspections, replacement and maintenance
  • pothole repair and crack sealing
  • mechanical sweeping and debris removal
  • graffiti removal
  • catch basin flushing and cleaning
  • bridge inspections and chipping
  • flushing of bridge joints
  • inspection, repair and replacement of “crash attenuation systems” that help cushion and redirect vehicles from barricades and barriers
  • inspection, repair and re-lamping of street lights
  • hydro pole replacement and repair
  • traffic camera inspection and repair
  • guiderail repair and replacement

In addition to bringing together and coordinating multiple divisions from across the City of Toronto to perform expressway maintenance, work has also been timed and coordinated with the Ministry of Transportation for planned work on the QEW approaching the Gardiner, as well as with Toronto Hydro. This coordination will help ensure the work is done efficiently and with the fewest impacts on the travelling public, local businesses and others that rely on the expressway.

Those who are travelling in and around the city should plan their route in advance, expect delays and leave plenty of extra time. Drivers should also consider using a wayfinding app to avoid the expressway closure.

Motorists can use Lake Shore Boulevard West, the Queensway, Bloor Street and Evans Avenue as alternative routes during the weekend closure.
