Gardiner Expressway construction affects
GO, TTC services, starting in late April



Update — Monday, August 4, 2:33 p.m.: The project to replace the median between Ellis Avenue and Dufferin Street ended today.


The City of Toronto will start three major construction projects on the Frederick G. Gardiner Expressway next month, starting immediately after the annual weekend closure for maintenance Friday, April 25, Saturday, April 26 and Sunday, April 27.

The three projects are:

  • replacing the deck on the elevated portion of the expressway between Exhibition Place and Grand Magazine Street (west of Bathurst Street) and demolishing the Garrison Road bridge under the expressway (east of Strachan Avenue). During this work, contractors will block one lane of traffic in each direction. The City expects to complete this work in December 2016, but will restore all traffic lanes from June until August 2015 duing the Pan Am / Parapan Am Games.
  • rehabilitating three bridges on the ground-level section of the expressway between the Humber River and Park Lawn Road. During this work, crews will block one eastbound traffic lane, while keeping all westbound lanes in this area open to traffic. The City expects to complete this work in December.
  • replacing the median on the ground-level section of the expressway between Ellis Avenue and Dufferin Street. During most of this work, contractors will block one lane of traffic in each direction. The City expects to compete this work in August 2014.

The City says it has planned this road work as part of its strategic rehabilitation program to bring the infrastructure to a state of good repair and improve the quality of the expressway.

Ongoing work to rehabilitate the major artery between York and Jarvis Streets continues until May. In addition, the City has scheduled work to install temporary shoring at 15 locations between York Street and Dan Leckie Way to finish by the end of April and interim repairs between Jarvis Street and Don Roadway to finish by the end of 2014.

While this work is taking place, the City is taking steps to minimize disrupting motorists, transit passengers and other members of the traveling public, including:

  • aligning the three projects and construction phasing;
  • selecting contractors to investigate methods to speed up the work;
  • changing traffic-signal timing to improve how traffic flows on nearby streets;
  • co-ordinating other construction projects with key stakeholders to avoid major work taking place along parallel routes; and
  • working to improve how the and emergency services co-ordinate activities when responding to incidents on the expressway.

GO Transit passengers riding buses operating along the 16 Hamilton / Toronto express, 18 Lakeshore West (early-morning / late-night), 21 Milton / Toronto, 31 Guelph / Georgetown / Toronto, 61 Richmond Hill / Toronto, 63 King City / Toronto, 65 Newmarket / Toronto, 71 Stouffville / Toronto and 90 Lakeshore East (early-morning / late-night) routes should expect delays.

Some work on the section between the Humber River and Park Lawn Road has already started and will prevent TTC) streetcars from accessing Humber Loop from Lake Shore Boulevard West. Streetcars operating along the 301Queen overnight, 501 Queen and 508 Lake Shore routes short-turn at Humber Loop, starting Sunday, March 30. Shuttle buses replace the cars west of the Humber.

Also, extra traffic on parallel routes may result as drivers try to avoid slow-downs on the Gardiner by driving on alternate routes. Expect delays on several nearby TTC routes, especially 15 Evans, 80 Queensway, 501 Queen, 504 King, 508 Lake Shore and 509 Harbourfront.
