TBMs Rexy and Renny have completed Eglinton Crosstown West tunnelling for the western section of the Toronto LRT extension project.
The two TBMs completed digging 6.3 km of which will bring future Eglinton Crosstown LRT service 9.2 km farther west with seven new stations along the route.
The 750-tonne, 131-metre-long machines excavated through the earth to construct two parallel tunnels stretching 6.3 kilometers 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 1.5-kilometre elevated section. TBM 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 route, the two TBMs excavated approximately 1.2 million 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 walls.
As Rexy and Renny head off into well-deserved retirement, work will 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.
The Toronto LRT extension project will connect Mount Dennis and Renforth Drive with the project being delivered in four major contracts including the stations, rail and systems, Advance tunnel 2 and Advance tunnel 2 and the elevated guideway contracts.
The Advance Tunnel project is the first phase of work for the 9.2 km extension of the Eglinton Crosstown LRT (future TTC Line 5). The extension will run mostly underground, westward from the future Mount Dennis station to Renforth Drive. The Eglinton Crosstown West Extension (ECWE) Advance Tunnel 2 Project is the second tunnel package, running between Jane Street and the future Mount Dennis Station.
The CAD 729.2 million (USD 532 million) Advance tunnel 1 contract was awarded to West End Connectors comprising Aecon Infrastructure Management, Dragados Canada and Ghella Canada to design, build and finance the tunnels for the Eglinton Crosstown West Extension project from Renforth Drive to Scarlett Road. The CAD 255 million (USD 186 million) contract for Advance tunnel 2 package was awarded to Strabag to design, build and finance the second underground segment of the Eglinton Crosstown West Extension, which includes a 500-metre tunnel from east of Jane Street to Mount Dennis Station.
The CAD 290 million (USD 211.6 million) package for the 1.5 km elevated guideway between Scarlett Road and Jane Street was awarded to Aecon Infrastructure Management.
In March 2024, Infrastructure Ontario and Metrolinx issued a Request for Qualifications (RFQ) for the Stations, Rail and Systems contract for the Eglinton Crosstown West Extension (ECWE). This package of work will be procured through a progressive design-build contract model. The scope of work includes 7 new stations, installation, testing, and commissioning of all rail and track components and systems equipment, road modifications and utility works.
