Metrolinx's tunnel boring machines (TBMs) have made it to their final destination in Mississauga at the tunnel launch site for the Eglinton Crosstown West Extension.
To make their way to the site at Renforth Drive and Commerce Boulevard, they were loaded onto trucks and driven carefully along the 60-kilometer (37-mile) route.
The cutter heads, each weighing about 65 metric tons and measuring about 6.5 meters (about 21 feet) in diameter, are so large they need a police escort to get to the site safely.
What happens in 2022?
The rest of the TBM parts, traveling from Europe in shipping containers, are scheduled to arrive in January. Once all the parts are on site, the team will start the process of assembling these machines, a process that takes months.
Once they are assembled, they’ll be lowered into the ground to begin the big dig.
The team has been working hard to get the launch shaft ready for these massive machines – that very large hole is 80 meters (262.5 feet) long, 20 meters (65.6 feet) wide and 17 meters (55.8 feet) deep. That’s big enough to hold about 10 Olympic-size swimming pools worth of water.
The TBM naming contest for the twin diggers for this project also closed this week.
Stay tuned in early 2022 for the announcement of the winning names.
