W.R. Allen Road south of Sheppard

Downsview Station Connection to Wilson Yard

Construction begins this month at W.R. Allen Road, south of Sheppard Avenue West, to build a connecting tunnel from Downsview Station to TTC Wilson Yard. The work is necessary as part of the Toronto-York Spadina Subway Extension (TYSSE) project.

Construction work includes installing roadway decking and building an excavation support system for the future subway tunnel. The work is expected to be complete in May 2010.

The City of Toronto has approved a noise by-law exemption which allows the contractor to perform overnight and weekend work to minimize traffic and neighbourhood disruptions.

Work Hours

Lane Restrictions during the Project

There will be lane restrictions on W.R. Allen Road, south of Sheppard Avenue West, in both directions. Overnight work may restrict W.R. Allen Road to one lane in each direction. Weekend work may restrict W.R. Allen Road to one lane northbound and two lanes southbound. Due to the nature of the work motorists may face traffic delays.

Construction Vehicle Access

Construction vehicles will access the construction site via W.R. Allen Road. During deliveries of construction material or equipment, traffic movement on W.R. Allen Road may be delayed or limited to a reduced speed. Your patience during this time is greatly appreciated.

We regret any inconvenience that may be caused as a result of this work.
