Description:

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, pre-stressed, rail carrying bridges that will be erected by lateral sliding during rail track blocks.
