The City of Toronto is closing
- the Frederick G. Gardiner Expressway in both directions between Highway 427 and Carlaw Avenue
from 10 p.m. Friday, April 25 until noon Sunday, April 27 for the City’s annual spring maintenance program.
Also, starting Monday, April 28, the City will close the eastbound lanes of the expressway between the Humber River and Carlaw Avenue overnight. During these closures, City workers will set up barriers for three major construction projects, all part of the City’s Gardiner Expressway strategic rehabilitation project.
While the Gardiner is closed, City workers will:
- clean 1,000 catchbasins to make sure they drain properly;
- install pavement markings on about 15 kilometres (9.3 miles) of highway;
- repair potholes;
- inspect bridges;
- maintain many of the static signs;
- maintain the closed-circuit television system, including six traffic cameras;
- inspect 200 overhead signs;
- repair about 300 metres (984 feet) of guard rails; and
- sweep and remove litter.
Closing the Gardiner affects buses operating along these GO Transit routes to and from the Union Station GO Bus Terminal: 16 Hamilton / Toronto express, 18 Lakeshore West early-morning / late-night, 21 Milton / Toronto, 31 Guelph / Georgetown / Toronto, 65 Newmarket / Toronto, 71 Stouffville / Toronto and 90 Lakeshore East early-morning / late-night.
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.
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, 75 Sherbourne, 76 Royal York South, 80 Queensway, 110 Islington South, 123 Shorncliffe, 172 Cherry St, 501 Queen, 504 King, 505 Dundas, 509 Harbourfront, 510 Spadina and 511 Bathurst.
Also, work on the project continues to block access to Humber Loop from Lake Shore Boulevard West for TTC streetcars operating along the the 301Queen overnight, 501 Queen and 508 Lake Shore routes. Shuttle buses replace the cars west of the Humber.
