Information about specific construction activities, traffic updates and construction notices will be regularly updated on this page.

Dates: 12:01 a.m., Saturday, July 25, 2020 to 5 a.m. on Monday, July 27, 2020

Location: Gardiner Expressway from the Don Valley Parkway (DVP) to Jarvis Street

Work Details:

From Saturday, July 25 to Monday, July 27, there will be traffic restrictions on the Gardiner Expressway from the DVP to Jarvis Street to safely transition the work zone from the north half of the expressway to the south half. These restrictions include:

  • From 12:01 a.m. to 11:59 p.m. on Saturday, July 25 there will be no westbound travel on the Gardiner Expressway from the DVP to Jarvis Street. Drivers traveling southbound on the DVP should exit at Richmond Street or Lake Shore Boulevard East to continue travelling westbound.
  • From 12:01 a.m. on Sunday, July 26 until 5 a.m. on Monday, July 27 there will be no eastbound travel on the Gardiner Expressway from Jarvis Street to the DVP and the eastbound on-ramps at Bay Street and Rees Street will also be closed. Drivers travelling eastbound should consider Lake Shore Boulevard East. If drivers are travelling to the DVP, they must access the DVP by the Don Roadway through Cherry Street and Villiers Street or Commissioners Street as vehicles will not be able to turn left onto the Don Roadway from Lake Shore Boulevard East.

Gardiner Expressway Deck Replacement – South Half

Dates: 5 a.m. on Monday, July 27 to Spring 2021

Location: Gardiner Expressway between Jarvis and Cherry Streets

Time: Mostly 24/7

Impact

  • Construction will fully replace the south half of the concrete deck and steel beams of the Gardiner Expressway between Jarvis and Cherry Streets
  • The Gardiner Expressway will be reduced to two lanes in each direction from York Street to the Don Valley Parkway (DVP)
  • The eastbound on-ramp at Jarvis Street remains closed for replacement
  • To maintain safety, the speed limit on the expressway will be reduced to 70 km/h through the work zone but drivers are encouraged to drive 60 km/h
  • Due to the current COVID-19 pandemic, the City is allowing for longer Lake Shore Boulevard East lane closures to help accelerate construction. Lake Shore Boulevard East will be reduced to one lane in each direction between Parliament and Jarvis Streets: Monday to Friday from 9 a.m. to 4 p.m., Friday to Sunday from 7 p.m. to 7 a.m. and Sunday to Thursday from 8 p.m. to 6 a.m. There also may be instances in the off-peak hours where traffic will be paused for 15 minutes so crews can safely remove and replace sections of the expressway above
  • Traffic-signal timing changes will be made to enhance traffic flow on nearby routes, to help mitigate traffic congestion
  • When sections of the expressway are removed, slurry water (a grey watery substance that is a by-product of cutting concrete) will fall from the expressway onto Lake Shore Boulevard. This water will fall throughout the deck removal and the lanes will be reduced on Lake Shore Boulevard where the water is anticipated to fall

Work Details

  • To complete this work faster and to be less disruptive to the public, the City is using an innovative construction technique called Accelerated Bridge Construction to replace the expressway deck.
  • This technique involves building the new sections of the expressway off-site and transferring the new sections into place where existing sections have been removed.
  • The benefits of this method are less dust and noise, and can reduce construction time by up to 40 per cent compared to traditional methods.
  • This project is unique as no other city in Canada has renewed a major expressway using this accelerated technique with the added complexities of the work zone located in an urban environment, in close proximity to buildings and over a major arterial road.

Dates: 12:01 a.m. on Monday, May 18, 2020 to Spring 2021

Location: Gardiner Expressway eastbound on-ramp at Jarvis Street

Time: Mostly 24/7

Impact:

  • Access to the Gardiner Expressway from the eastbound on-ramp at Jarvis Street will be fully closed until Spring 2021 so that crews can safely rehabilitate the ramp.
  • Lane closures will occur on one or two of the most north lanes on the eastbound Lake Shore Boulevard East between Lower Jarvis and Parliament Streets during the following times: daytime off-peak hours (Monday to Friday, from 9 a.m. to 4 p.m.); nighttime off peak hours (Sunday to Thursday from 9 p.m. to 6 a.m.); and 24-hour weekends (from 12 a.m. to 11:59 p.m.) so workers can remove and replace the bridge deck sections alongside corresponding construction works*
  • A minimum of one lane on the eastbound Lake Shore Boulevard East will remain open to traffic heading east
  • While the majority of the most disruptive work will be completed before 11 p.m., some disruptive work may take place overnight for the safety of crews and the travelling public.
  • Advanced signage will be in place to advise motorists of the ramp closure.
  • Please plan your travel in advance, be patient on the roads, and consider alternate routes or public transit.

Alternative Routes:

During this construction, drivers should consider using alternate routes such as the eastbound Bay Street on-ramp, Lakeshore Boulevard East or the Don Roadway to the Don Valley Parkway.

Work Details:

The section of the Gardiner Expressway between Jarvis and Cherry Streets is nearing the end of its service life and this major work will rehabilitate the eastbound Jarvis Street on-ramp, including replacing the entire deck and steel girders.

*Please note lane closure hours could change depending on COVID-19 situation, however one lane on eastbound Lake Shore Boulevard East will always remain open

Gardiner Expressway Deck Replacement – North Half

Dates: 5 a.m. on Monday, October 14 to July 27, 2020

Location: Gardiner Expressway between Jarvis and Cherry Streets

Time: Mostly 24/7

Impact:

  • Construction will fully replace the north half of the concrete deck and steel beams of the Gardiner Expressway between Jarvis and Cherry Streets
  • The Gardiner Expressway will be reduced to two lanes in each direction from York Street to the Don Valley Parkway (DVP)
  • To maintain safety, the speed limit on the expressway will be reduced to 70 km/h through the work zone but drivers are encouraged to drive 60 km/h
  • There will be closures on the westbound lanes of Lake Shore Boulevard East during off-peak hours (between 9 a.m. to 4 p.m., Monday to Friday and from 10 p.m. to 5 a.m. Sunday to Thursday). There may be instances in the off-peak hours where traffic will be paused for 15 minutes so crews can safely remove and replace sections of the expressway above.
  • Due to the current COVID-19 situation, the City is allowing for longer Lake Shore Boulevard East lane closures to help accelerate construction for the rehabilitation work to the Gardiner Expressway between Cherry Street and Lower Jarvis Street. Lake Shore Blvd E westbound lanes will be reduced to one lane from 9 a.m. to 4 p.m., Monday to Friday; from 8 p.m. to 6 a.m., Sunday to Thursday; and from 7 p.m. to 7 a.m. Friday to Sunday.
  • Traffic-signal timing changes will be made to enhance traffic flow on nearby routes, to help mitigate traffic congestion.
  • When sections of the expressway are removed, slurry water (a grey watery substance that is a by-product of cutting concrete) will fall from the expressway onto Lake Shore Boulevard. This water will fall throughout the deck removal and lanes will be reduced on Lake Shore Boulevard where the water is anticipated to fall.
  • During this construction, the Gardiner Expressway will be reduced to two lanes in each direction from York Street to the Don Valley Parkway (DVP) and only one ramp will be closed at a time.

Alternate Routes

  • During construction, drivers should plan ahead and consider alternate routes such as Lake Shore Boulevard and the southbound Don Valley Parkway (DVP) to the Richmond Street exit.
  • Motorists entering the downtown core may use the off-ramp Yonge-Bay-York Streets or Spadina Avenue.
