The Scarborough Subway Extension is a 7.8 kilometre extension of TTC’s Line 2 Bloor-Danforth Subway, from the existing Kennedy Station northeast to McCowan Road/Sheppard Avenue. The line will include three new stations at Lawrence Avenue and McCowan Road, Scarborough Centre and a terminal station at McCowan Road and Sheppard Avenue. Tunnelling is one of the first phases of work for the project. A separate advance tunnelling contract will be issued to help move the project forward on an accelerated timeline.
On August 20, 2020, the province invite the selected teams from the Request for Qualifications process to respond to an RFP that details how they plan to design and deliver the tunnelling work for the SSE. Upon evaluating the proposals received, Infrastructure Ontario and Metrolinx expect to award this tunnelling contract in mid-2021.
