Davenport Diamond Rail Grade Separation Project

The Davenport Diamond Rail Grade Separation project is part of Metrolinx’s GO Expansion program. To support two-way, all-day GO service on the Barrie line, a rail grade separation was constructed at the Davenport Diamond, one of the busiest train intersections in North America, where the Barrie GO corridor meets the CP Rail tracks. The project included the construction of a new rail grade separation between GO Transit’s Barrie line and CP Rail’s North Toronto subdivision, as well as the addition of a second mainline track on the Barrie line.

The project also involved staged demolition and reconstruction of a rail-over-road bridge at Bloor Street, rehabilitation of rail-over-road bridges at Dupont Street and Davenport Road, construction of a new electrical and communications building, installation of MSE walls, a stormwater drainage system, fire life safety measures, public egress, and a pedestrian underpass at Paton Road. Following the completion of the grade separation, new public spaces and multi-use trails were constructed through the rail corridor, connecting neighborhoods previously cut off by the Barrie line and enhancing the community experience.
