The Eglinton Crosstown project will be tightly integrated with other transportation modes such as bus routes, three subway stations and various commuter rail lines. It is the largest transit expansion in Canada’s history and a project of this size can present some unique challenges.
Preserving a piece of history
There was a need for excavation work under a four-storey, 45-metre long heritage building that would form part of a new station. After a careful assessment, the building was lifted and moved 60 metres from the site on specially constructed tracks. It was eased back into place just over a year later.
Eglinton is being built in the busy heart of a major city, so minimizing disruptions to traffic and the community is a priority. One way we resolved this was by switching from the bottom-up construction originally planned on some parts of the line to top-down construction instead. This allowed crews to dig down a couple of metres, lay a concrete slab and backfill it. Construction will then continue underneath, allowing the roads to remain open.
Three of the stations are also being built by the sequential excavation method (SEM) to avoid substantial utility relocations and to minimize disruptions to traffic and the public.
