Gardiner Expressway Deck Replacement – North Half

Dates: 5 a.m. on Monday, October 14 to mid-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 girders 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
  • 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/hr
  • There will be closures on the westbound lanes of Lake Shore Boulevard East during off-peak hours (between 10 a.m. to 3 p.m. and 10 p.m. to 5 a.m.) and 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
  • The majority of the most disruptive work should be completed by 11 p.m., however, in some instances disruptive work must be performed overnight for the safety of crews and the travelling public
  • 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 and only one ramp will be closed at a time

Fall Maintenance Weekend Coordinated with Construction Staging

  • To help minimize the disruption to the travelling public, the annual fall maintenance closure has been coordinated with plans to set up the construction work zone on the Gardiner deck to avoid additional closures
  • The Gardiner Expressway will be fully closed from Don Valley Parkway/Carlaw Avenue to Highway 427/Queen Elizabeth Way from 11:59 p.m. on Friday, October 11 until 5 a.m. on Monday, October 14
  • Crews will set up the construction work zone on the eastern part of the expressway between Jarvis and Cherry Streets and perform fall maintenance on other sections of the expressway

Alternate Routes

  • During construction, drivers should plan ahead and consider alternate routes such as the southbound Don Valley Parkway to the Richmond Street exit

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 that it causes less dust and noise, and can reduce construction time by up to 40 per cent compared to traditional methods
  • This project is significant as no other city in Canada has renewed a major expressway using this accelerated technique at this scale with the added complexities of the work zone located in an urban environment, in close proximity to buildings and over a major arterial road

Next Phase

  • Once the Sherbourne/Jarvis off-ramp re-opens in Spring 2020, the westbound Yonge-Bay-York off-ramp will close again so crews can safely replace the concrete deck and steel girders of the expressway next to the ramp
  • In mid-2020, construction will move to the third and final phase which will replace the south half of the expressway deck and the eastbound on-ramp at Jarvis Street
  • The entire project is expected to be completed in early 2021

Dates: 11:59 p.m. on Friday, October 4 to Spring 2020

Location: Gardiner Expressway westbound Sherbourne/Jarvis off-ramp

Time: Mostly 24/7

Impact

  • The Gardiner Expressway westbound Sherbourne/Jarvis off-ramp will be fully closed for replacement
  • So crews can safely set up the work zone, the westbound Gardiner Expressway will be reduced to two lanes from the DVP to just west of the Sherbourne/Jarvis off-ramp from 10 p.m. on Friday, October 4 to 5 a.m. on Saturday, October 5
  • 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, consider alternate routes or public transit

Alternate Routes

  • During construction, drivers should consider alternate routes such as the westbound Gardiner Expressway Yonge-Bay-York off-ramp or the southbound Don Valley Parkway to the Richmond Street exit

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 replace the existing westbound Sherbourne/Jarvis off-ramp.

The next phase of construction will also begin in October and will fully replace the north half of the concrete deck and steel girders of the Gardiner Expressway between Jarvis and Cherry Streets.

F.G. Gardiner Expressway Rehabilitation, Jarvis Street to Cherry Street

Completed – Westbound Yonge-Bay-York Off-Ramp Rehabilitation

Map of Phase 1 Work – Extensive repairs to the westbound Yonge-Bay-York off-ramp

Dates: 10 p.m. on July 15 to September 22, 2019

Location: Gardiner Expressway westbound Yonge-Bay-York off-ramp

Time: Mostly 24/7

Impact

  • The Gardiner Expressway westbound Yonge-Bay-York off-ramp will be fully closed
  • To safely complete some of this work, the westbound on-ramp at Jarvis Street that runs underneath the westbound Yonge-Bay-York off-ramp will be closed overnight from 12 a.m. to 5 a.m., August 1 to 8 and August 26 to 30 except on Friday and Saturday nights when it will be open.
  • While the majority of the most disruptive work will be completed before 11 p.m., some disruptive work will be occasionally completed during night hours when nearby traffic is reduced as a safety precaution
  • Advanced signage will be in place to advise motorists of the ramp closure
  • With lane restrictions on the DVP in place for other construction during this work, please plan your travel in advance, be patient on the roads, consider alternate routes or take public transit

Alternate Routes

  • During construction, consider using other westbound off-ramps such as Sherbourne Street or Spadina Avenue
  • To access downtown, consider alternate routes such as exit the DVP onto Richmond Street, exit the Gardiner at Jarvis Street and enter from the east, exit the Gardiner at Spadina Avenue or travel on Lake Shore Boulevard westbound to access Yonge, Bay or York Streets

Work details

This closure will allow crews to make extensive repairs (also known as rehabilitation) to the westbound Yonge-Bay-York off-ramp as part of the Strategic Rehabilitation of the expressway from Jarvis Street to Cherry Street.

This work will:

  • remove and replace the existing asphalt, joint assemblies, approach slabs, light posts, barrier walls, and curbs;
  • install new deck drains and maintain existing drainage systems;
  • patch concrete on the deck; and
  • waterproof and pave the new deck.

Completed – Access Platform Installation

Dates: Sunday night to Thursday night, until June 13, 2019

Location: Westbound lanes of Lake Shore Boulevard East from Cherry Street to Jarvis Street

Time: Overnight rolling lane closures from 10 p.m. to 5 a.m.

Impact:

  • This work will require intermittent 15-minute rolling lane closures hourly, overnight from 10 p.m. to 5 a.m. on the westbound lanes of Lake Shore Boulevard.
  • At least one westbound lane will always remain open to reduce the impact on traffic.

Work details: These closures will allow crews to install access platforms for forthcoming work on the underside of the Gardiner Expressway. Access platforms are necessary for crews to gain access to the underside of the Expressway to later complete necessary repairs to bearings and bearing seats.

Please note: Further lane closures will be required on Lake Shore Boulevard East between Cherry Street and Jarvis Street so crews can continue to install access platforms on the underside of the Gardiner Expressway and conduct other repairs. A series of lane closures is anticipated to continue until December and may take place during the day and/or overnight. The details, timing and impact of this work will be communicated in advance.
