This week, TTC crews continue geotechnical drilling and general surveying in various locations to prepare for the future extension of Line 2 (Bloor - Danforth) to Scarborough Centre.
Starting Tuesday, January 10, geotechnical crews are drilling 55 boreholes in the road and City right-of-way to determine the underground conditions along the future subway corridor. They’ll temporarily block traffic lanes on Borough Drive, Progress Avenue, McCowan Road, Danforth Road and Eglinton Avenue East. Surveyors work at the same time at each site to determine the exact location of surface and underground infrastructure.
Geotechnical crews and surveyors started working along this corridor last October and likely continue until this December. They’ll work at each borehole location for about six weeks. At each site, you’ll see equipment and work trucks in traffic lanes. They’ll also temporarily spray-paint markings on the road and sidewalks. Expect dust, noise and vibration as they work.
Crews mostly work from about 7 a.m. until 7 p.m. Mondays to Fridays. However, they won’t block traffic lanes in the peak direction during rush hours. For example, they’ll work in southbound lanes on McCowan Road from 9 a.m. until 7 p.m. and northbound from 7 a.m. until 4 p.m.
The TTC says this work will not affect local bus services.
These images show the “preferred alignment”. Some City councillors propose a different route in the Scarborough Centre area.
