TTC and Region of York contractors continue to work on the project to extend the Spadina branch of the 1 Yonge - University - Spadina subway northwest to Vaughan.

Contractors have postponed excavation work at the future York University Station site due to poor weather, but starting today, Monday, March 3, they’ll be resuming the work. They expect this phase of the project to continue for three months — or until about Friday, June 6 — and it requires crews to use a drill rig for two weeks. The map shows the excavation zone and identifies it as the “Excavation Light Scoop” area.

During the drill rig work, expect more construction noise from the auger as it shakes off soil or debris while drilling.

Contractors have installed noise and vibration monitors in key locations on and near the construction site to record noise and vibration levels. Construction activities normally occur Mondays to Saturdays from 7 a.m. until 7 p.m.

Work on the subway project also restricts or closes traffic lanes on York University’s Keele Campus during off-peak hours from Tuesday, March 4 until Monday, March 10 for sanitary and storm sewer work at:

York Boulevard : The work reduces eastbound lanes between James Gillies Street and the TTC Busway. A single lane of traffic will be open and contractors will station flag personnel at the intersection of York with James Gillies to direct motorists and pedestrians.

Contractors will station flag personnel at this location for transit, traffic and pedestrian flow.

Due to the nature of the work, motorists and transit users may face traffic delays. Traffic control personnel will be on site to direct bus operators, and motorists and pedestrians.

Brampton Transit, GO Transit, the TTC and York Region Transit continue to detour buses around the construction site and throughout the Keele Campus.
