Through the summer, the 512 St. Clair route will be under construction for various projects:
- Modification of loading islands,
- Reconstruction of the portal ramps and track at St. Clair West Station,
- Reconstruction of overhead wiring at St. Clair West Station,
- Reconstruction of the roofs at St. Clair Station streetcar and bus levels.
Buses are now operating over the entire route and this will continue until the Labour Day weekend when streetcars will return from St. Clair West Station to Keele. The work at St. Clair Station will not complete until late fall 2016, and buses will remain on the eastern section of the route.
The buses share the road lanes with auto traffic and generally do not make the trip as quickly as the streetcars. This article shows comparative data from early June 2016 when streetcars were still operating and late June after the buses took over.
