Tunnel Boring Machine “Torkie” Tunnels Under Interchange Way

October 29, 2013

Tunnel boring machine (TBM) “Torkie” completed the milestone this week of tunnelling under Interchange Way. “Torkie” began tunnelling again on September 13, 2013, from the northern launch shaft at the Highway 407 station site, and is headed toward the Vaughan Metropolitan Centre Station’s extraction shaft. This extraction shaft is located south of Highway 7 and west of Jane Street.

“Torkie” will tunnel just over one kilometre in this drive and will place approximately 686 tunnel liners in the tunnel.

“Torkie” is anticipated to complete this tunnel drive from Highway 407 Station before the end of the year.

You may follow the progress of “Yorkie” and “Torkie” on our website under “Tunnelling Progress” and “Construction Activity Maps”.
