New drone images released by Metrolinx are provide a close look at construction progress on the north end of Toronto’s future Ontario Line subway, where major infrastructure work is moving from foundations and excavation into visible above-ground structures.
The work highlighted in the images is being delivered by Trillium Guideway Partners, a consortium led by Acciona and AMICO, which is responsible for major civil works on the northern section of the Ontario Line, including elevated guideway structures, stations and bridge-related infrastructure.
“Across Toronto’s northeast, the Ontario Line is becoming more visible every day as foundations give way to bridges, guideways and station structures,” Metrolinx officials said in a release. “Over the coming months, residents will begin to see even more of the future subway line emerge above ground as construction continues across the area.”
The drone photos showcase several key construction milestones, including:
- Foundation and support structures for the Don Valley bridge crossing
- Piers that will support the elevated guideway at Thorncliffe Park Station
- Excavation of the site for the operations, maintenance and storage facility
- Road excavation and construction of a track retaining wall at the Beth Nealson underpass
- Bridge piers at the West Don Crossing
- Guideway piles for Flemingdon Park Station
- Basement piling and station wall construction at Don Valley Station
Construction crews are now progressing beyond early site preparation, with more of the future subway line expected to become visible above ground in the months ahead.
The Ontario Line is a planned 10-mile (16-kilometre) subway, elevated and at-grade rail line that will connect Exhibition Place in Toronto’s west end with the Eglinton Crosstown light-rail line at Don Mills Road. The route will travel through downtown Toronto and include connections to multiple transit services, including light rail and regional heavy rail networks.
