TBMs Rexy and Renny have completed all running tunnel boring works on Ontario’s $4.7bn Eglinton Crosstown West Extension. Over the past two years, the twin TBMs have been the driving force behind progress on the western underground segment of the extension. The project will bring the future Eglinton Crosstown LRT service 9.2km farther west with seven new stations along the way.
The TBMs excavated two parallel tunnels stretching 6.3km from Renforth Drive in Mississauga to west of Scarlett Road in Etobicoke, where the future line will come to the surface and transition to a 1.5km elevated section.
Renny broke through the final wall and emerged from the tunnel at the extraction shaft in May, approximately three weeks after the other TBM, Rexy, reached the finish line.
Along the way, Rexy and Renny excavated approximately 1.2M tonnes of soil and rock and installed a total of more than 52,000 pre-cast concrete segments to build 7,433 sturdy rings to support the tunnel.
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.
Work will now continue at the extraction shaft to lay the foundations and form the structure of the future tunnel portal. Over the months to come, crews will finish up work on the passageways that connect the tunnels.
Along the route between Scarlett Road and Jane Street, work is happening to prepare sites for construction of the elevated segment, which will run along the north side of Eglinton Avenue West. Crews are also preparing work sites from east of Jane Street and Mount Dennis Station to excavate the eastern underground section of the line, which will connect the extension to future Eglinton Crosstown LRT service.
