Last week the Eglinton Crosstown West Extension reached another milestone: Renny, the first TBM to start tunnelling passed the halfway point, digging over 3 km of the roughly 6 km tunnel.  

The 9.2km extension of the Eglinton Crosstown LRT will run from the future Mount Dennis station to Renforth Drive and will operate mainly underground. Once complete, it will create a continuous rapid transit line that stretches from Scarborough, through midtown Toronto, and into Mississauga.  

Tunnelling started last April from the tunnel launch site near Renforth Drive, with the TBMs making their way to west of Scarlett Road, where they will emerge from underground. Rexy, the second TBM is not far behind Renny. Since July, Rexy has tunnelled 2.45 km and reached the first headwall location at Martin Grove Road.
