This project will improve commuter service reliability, eliminate at-grade conflicts with freight rail traffic, and support overall improvements to service on the GO Transit Georgetown/Weston rail corridor through the construction of a new rail-rail grade separation. Interlocking steel pipe piles are being used to form the outer walls of the depressed corridor. The main contract involves the construction of several precast, prestressed, rail carrying bridges that will be erected by lateral sliding during rail track blocks.
