Photos of the Davenport Diamond grade separation project in Toronto's west end. Planned increases in GO Train services between Barrie and Toronto necessitated the separation of the at-grade, rail-to-rail crossing of the GO Train Barrie line and the CP North Toronto subdivision tracks. The elevated Davenport Diamond Guideway is a 1.4 km long, 8.5 m high bridge. Started in 2017, it is scheduled to be completed in 2023.
