One of two bridges the Ontario Line subway is building over the Don River and Don Valley Parkway will be as tall as a 10-storey building when complete.

The Don Valley Crossing, a smaller arch bridge, will carry elevated rail and be supported by five piers rising 32 metres above the valley floor. In the past year, construction progressed from initial foundations to rising concrete supports, Metrolinx said Wednesday.

The bridge will link Thorncliffe Park and Flemingdon Park stations on the 15.6-kilometre Ontario Line, which connects Exhibition Place in the southwest to the Line 5 LRT in the northeast across 15 stops.

Some residents have raised concerns that the Don Valley Crossing may block a popular view of the Toronto skyline from Leaside Bridge. The source material does not provide a completion date for the bridge or the Ontario Line overall.
