The Don Valley Crossing bridge will be a signature piece of infrastructure in Toronto’s transportation network. The mega infrastructure project commenced construction in 2024 as part of the Ontario Line subway. When finished, it will cross the Don Valley, linking the Crosstown LRT in the north with Exhibition Place in the south. The 15.6-kilometre line includes 15 new stations and will run through the downtown core. The Ontario Line will cross the Don Valley twice. One is the Lower Don Bridge, a smaller but architecturally significant steel arch bridge. But the Don Valley Crossing bridge will be the more prominent one. Rising 38 metres above the valley floor, its balanced cantilever design will see it become the first high-level crossing to be built in the area since 1927. From the Leaside Bridge’s vantage point, it will be a permanent addition to Toronto’s skyline.

Significance and Scope of Toronto’s Don Valley Crossing Bridge
The Don Valley Crossing bridge is significant to Toronto’s growing transit system. The bridge will carry subway trains over a deep urban valley, linking communities more effectively. It will also improve daily commutes and showcase scenic city views. Though its concrete form is utilitarian, its scale qualifies it to be a visual icon. Its construction is a vital step towards sustainable urban mobility. In scope, the bridge is a major undertaking in the Ontario Line project. Its creation involves bridging difficult terrain, preserving existing infrastructure, and incorporating new transportation corridors. The Don Valley Crossing bridge also embodies a marriage of function and legacy, blending engineering imperatives with city-building aspirations. When completed, it will not only be a vital transit link but also a viewing area, much like the Bloor Viaduct. The project is also anticipated to compliment the construction of the multi-billion-dollar Ontario line. Together with the Highway 413 project currently ongoing, Ontario’s highway network is set to be transformed within the coming years.
