City of Toronto to begin major construction work on Adelaide Street bundling water, track, road and cycling upgrades

Construction road sign

Beginning next week, the City of Toronto is undertaking major construction on Adelaide Street in sections spanning from Bathurst Street to Parliament Street to upgrade critical water, road and cycling infrastructure, as well as to reinstate TTC streetcar tracks in advance of Ontario Line construction. The project, in coordination with the TTC and Metrolinx, bundles several construction needs on Adelaide Street into one project to complete the work as quickly as possible and minimize prolonged disruption.

The work bundled into this project includes:
• replacing a vintage watermain that’s more than 115 years old and the City-owned portion of substandard water services from York Street to Victoria Street
• renewing the roadway on Adelaide Street, from Spadina Avenue to York Street
• reinstating streetcar tracks on Adelaide Street, from Charlotte Street to York Street, in advance of Metrolinx Ontario Line subway construction. These tracks will provide operational flexibility and improved service for TTC streetcar customers during the many construction projects downtown.
• relocating the cycle track on Adelaide Street, from Bathurst Street to Parliament Street, to the north side of the street to improve safety and installing new bike signals
• upgrading pedestrian infrastructure at various locations along Adelaide Street, from Spadina Avenue to York Street, to improve safety.

Construction will be conducted in phases and major travel restrictions will reduce sections of Adelaide Street to one lane of shared traffic and partial intersection closures.

Details of upcoming traffic restrictions:
• On Monday, October 24, there may be some localized closures on Adelaide Street, in sections from Duncan Street to Bay Street, to prepare for the work to begin.
• Beginning Tuesday, October 25, Adelaide Street, from Duncan Street to Bay Street, will be reduced to one shared lane for vehicles and cyclists. There will be a partial intersection closure on Adelaide Street at Simcoe Street, with no through traffic south of Adelaide Street. Construction on the stretch between Duncan Street to York Street is expected to be completed by the end of November.
• Beginning Thursday, October 27, the intersection of Adelaide Street and University Avenue will be reduced to one lane in each direction. Anticipated completion of this work is before Tuesday, November 15.
• Beginning the week of Monday, November 7, Adelaide Street, from Widmer Street to Duncan Street, will be reduced to one shared lane. Adelaide Street will have partial intersection closures at John and Duncan Streets with no through traffic south of Adelaide Street.
• Once work on Adelaide Street from Duncan Street to York Street is complete, Adelaide Street, from Spadina Avenue to Widmer Street, will be reduced to one shared lane and there will be partial intersection closures at Peter and Widmer Streets with no through traffic south of Adelaide Street and no access to Charlotte Street from Adelaide Street.
• Adelaide Street, from Bay Street to Victoria Street, will also be reduced to one shared lane for watermain replacement and upgrades to cycling infrastructure. The City will share timing details of this work once confirmed.

Construction is anticipated to be completed in spring 2023. Depending on progress, lanes may re-open during winter months and close again for finishing touches when weather warms.

Due to the nature of construction and activity sequencing, there may be periods of time when the work zone or sections of the work zone appear inactive. This is particularly true during watermain replacement when the new watermain is being flushed and water quality tested before being put into service.
Local businesses in this area will be open as usual and pedestrian access to businesses around the site will be maintained.

Due to the major travel restrictions on Adelaide Street to facilitate this work, drivers are urged to avoid travelling through the area unless travelling to a destination on Adelaide Street.

With so much construction taking place in the downtown core, drivers are advised to plan their travel in advance, expect delays, consider taking public transit and obey signage around work zones for the safety of the work crews.
