The Ontario Line's elevated infrastructure is taking shape faster than expected. Piling work for the elevated guideway is now over halfway complete, with crews beginning work on the above-ground piers that will support the trackbed.
Roughly three kilometres of elevated guideway will carry trains along the northwestern portion of the 15.6-kilometre route between Exhibition Place and the Don Mills and Eglinton intersection. The line is part of the $27 billion project with a vague early 2030s opening timeline.
Metrolinx shared an update on three elevated stations, their connecting guideway, and the maintenance and storage facility. Sixteen piles for the future elevated guideway have been installed, paving the way for work on foundations and the guideway itself. Thirteen guideway piles are complete, and ten guideway piers are now in place.
A massive 115-metre maintenance pit has been excavated near Overlea Boulevard, with crews beginning work on the facility's train wash and maintenance buildings. Trains will access this elevated stretch via a high-level bridge over the Don Valley, emerging from a tunnelled section to the south via a portal at Minton Place.
At a height of approximately 30 metres above the valley floor, the bridge along with the elevated guideway to the north will offer commanding views of the Toronto skyline. Metrolinx has been highlighting this feature on social media, emphasizing that commuters will get a unique perspective of the city during their rides.
