CrosstownTO - Published on Jan 22, 2015
The Crosstown project hit a milestone on Jan 21, 2015. The West Tunnel TBMs broke through into the extraction shaft at Allen Road. That means the tunneling from Black Creek to Allen Road is complete.
The next milestone is to move the tunnel boring machines from the extraction shaft at Allen Road, up and over the TTC subway, and re-launch on the other side of Allen Road to complete the tunneling to Yonge Street.
