On December 9, the board of the Toronto Transit Commission (TTC) awarded Hatch Mott MacDonald (HMM) the contract to design the tunnel for Toronto’s new Scarborough subway.
Michael Schatz, HMM’s Managing Director for Canada, said, “HMM is honored to be contributing once again to Toronto’s transportation infrastructure. We are proud of our long-standing relationship with the TTC, going back to the 1950s. We have had key design roles for the bored tunnels on the current operating system and for the underground work for the Toronto York Spadina Subway Extension and the Eglinton Crosstown LRT projects currently under construction.”
The 4.6-mile (7.5 kilometers) three-stop subway was approved by the city council in October 2013. It will extend the existing Bloor-Danforth subway line to Scarborough Town Centre, replacing the aging Scarborough Rapid Transit line, which went into service in 1985.
The city has begun work on an environmental assessment, which will determine the route of the subway, and public consultation.
