Line 1 Yonge Subway Extension - preliminary studies
Starting as early as March 4, 2019
The planned Line 1 Yonge Subway Extension is a cross-jurisdictional project from the City of Toronto into the City of Markham, City of Vaughan and the Town of Richmond Hill. With the preliminary planning, design and engineering phase underway, crews will begin geotechnical testing in Toronto along Yonge Street and some side streets from Finch Avenue to Steeles Avenue.For more information on this project, visit the project page.
What we are doing and why?
- Starting as early as March 4 (pending weather), crews will use a drill rig to bore holes and extract samples. Each borehole location will take approximately three to four weeks to complete.
- At the end of each work day crews will restore the roadway.
- Due to the nature of this work, at times, there will be construction-related noise from equipment. This preliminary work is typical for subway planning, and does not create significant noise.
Testing will occur on Yonge Street at the following locations:
- north of Abitibi Avenue (southbound curb lane) - starting as early as March 4
- south of Cummer Avenue (centre lane) - starting as early as March 4
- south of Connaught Avenue (southbound curb lane) - starting as early as March 4
Traffic will be maintained through the work zones. Depending on the location, work will either take place in the curb lane or the centre lane – some temporary turning restrictions may apply. Access to driveways will be maintained.
Work will generally take place during the daytime between 9:30 a.m. and 3:30 p.m. This includes time to set up and remove the work area in addition to drilling/sampling.
