City closing Gardiner Expressway
for seasonal maintenance this weekend



The City of Toronto is closing

  • the Frederick G. Gardiner Expressway in both directions between Highway 427 and Carlaw Avenue

from 11 p.m. Friday, October 21 until 5 a.m. Monday, October 24 for the City’s annual fall maintenance program.

While the Gardiner is closed, City workers (and contractors) are:

  • resurfacing 1.4 “lane kilometres” (0.87 “lane miles”) of roadway;
  • sealing cracks and repairing about 1,500 metres (4,921 feet) of asphalt surfaces;
  • core-testing asphalt core and estimating future surface maintenance needs;
  • inspecting in-depth and chipping of 15 bridges between Kipling and Jameson Avenues;
  • cleaning and repairing 300 catch basins;
  • flushing and inspecting culverts;
  • regrading shoulders to restore drainage at several locations;
  • installing 900 metres of permanent median “tall wall”;
  • paving at various locations, including the ramp from Jameson Avenue to the westbound expressway;
  • marking lines on the pavement between Exhibition Place to Spadina Avenue;
  • maintaining signs for the entire length of the roadway;
  • maintaining 21 closed-circuit television (CCTV) cameras, nine variable message signs (VMS) and 30 equipment cabinets
  • installing 37 signs at exit ramps
  • repairing about 100 metres (328 feet) of guardrail;
  • sweeping and removing debris;
  • inspecting, repairing and re-lamping street lights; and
  • repairing potholes.

Closing the Gardiner affects buses operating along these GO Transit routes to and from the Union Station GO Bus Terminal:

  • 16 Hamilton / Toronto express;
  • 18B 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.

At most times while the expressway is closed, GO is likely detouring the buses along The Queensway and Lake Shore Boulevard, instead of the Gardiner, but the buses serve all regular stops. However, GO Transit Control monitors road conditions and may direct bus drivers to detour along other streets, depending on traffic flow.

From 9 a.m. until 8 p.m. Saturday, October 22 and Sunday, October 24, GO starts and ends all buses operating along the 21 Milton / Toronto and 31 Guelph / Georgetown / Toronto routes at Port Credit GO Station. Passengers must travel by train between Union Station and Port Credit.

Motorists that would usually drive along the Gardiner will seek alternate routes on nearby parallel streets, increasing traffic volumes along Lake Shore Boulevard, The Queensway, King and Queen Streets, among others.

The extra traffic may delay TTC service along these routes: 6 Bay, 15 Evans, 29 Dufferin, 47 Lansdowne, 63 Ossington, 65 Parliament, 66 Prince Edward, 72 Pape, 75 Sherbourne, 76 Royal York South, 80 Queensway, 110 Islington South, 121 Fort York - Esplanade, 123 Shorncliffe, 501 Queen, 504 King, 505 Dundas, 509 Harbourfront, 510 Spadina, 511 Bathurst and 514 Cherry.
