Rexy, one of two twin TBMs boring the western underground segment of Ontario’s $4.7bn Eglinton Crosstown West Extension has broken through the final wall after 21 minths of driving.
The 750-tonne, 131m long machine has broken through and emerged from the tunnel at the Scarlett Road extraction shaft, where the TBMs will be disassembled and removed from the ground.
Rexy has spent the last two years carefully excavating one of two 6.3km tunnels that stretches from Renforth Drive to Scarlett Road, where the future line will come to the surface and transition to an above-ground section.
The Eglinton Crosstown West Extension is being constructed by WestEnd Connectors Construction, consisting of Dragados Canada, Inc., Aecon Infrastructure Management Inc., and Ghella Canada Ltd, and will bring future Eglinton Crosstown LRT service farther west through York, Etobicoke, and into Mississauga. The project includes seven new stations along a route of 9.2km.
Rexy’s twin – Renny – is not far behind and will arrive at the extraction shaft in the weeks to come.
Once crews take the TBMs apart in the extraction shaft, they will lift them from the ground piece by piece. Rexy and Renny will be retired from work on the project, but there’s still more tunnelling work to come.
Work will continue at the extraction shaft to lay the foundations and form the structure of the future tunnel portal. Work has also started to prepare construction sites for the eastern underground segment of the line that will run from east of Jane Street to Mount Dennis Station.
