Clark Avenue West Thornhill construction: TTC detour, starting October 15

City of Vaughan contractors are working on a project to install bike lanes on

  • Clark Avenue West, both sides, between Jason Street / David Lewis Drive and Yonge Street.

During the project, contractors also

  • improve transit stops;
  • improve intersection; and
  • rehabilitate and resurface the roadway.

Starting Thursday, October 15, the work zone blocks vehicles from turning right from southbound Atkinson Avenue onto westbound Clark West.

The TTC is detouring buses along this route, while the intersection is blocked:

  • 160 Bathurst North.


Contractors started working on the bike-path project in “early June”. This phase of construction on Clark Avenue West and the resulting TTC detour continue until further notice.

During ongoing construction on Clark Avenue West, York Region Transit passengers aboard buses along these routes can expect delays:

  • 5 Clark;
  • 23 Thornhill Woods; and
  • 77 Highway 7.

Construction to install bicycle lanes and the resulting TTC and YRT service changes continue “until December” or until December 31.

Construction crews installed a new water main under Clark West between Bathurst and Yonge — affecting TTC and YRT services — in 2020.

Contractors return to Clark Avenue West in 2021 to repave the roadway and improve transit stops and intersections.

160 Bathurst North

Southbound buses operate along their regular route.

Starting Thursday, October 15, northbound buses operate along their regular route to Atkinson Avenue and Centre Street, then detour:

westward along Centre; and then
southward along Bathurst Street to beyond Clark Avenue West,
ending their trips.

Northbound buses skip their regular stops

  • on Atkinson Avenue at Campbell Avenue and Rodeo Drive, beyond Spring Hill Boulevard and at Clark Avenue West and
  • on Clark Avenue West across from York Hill Boulevard.

Instead, northbound buses drop off or pick up passengers at temporary stops

  • on Centre Street beyond Atkinson Avenue and
  • on Bathurst Street at East Promenade.
