Project Description

In November 2015, Crosslinx Transit Solutions (CTS) was awarded the Eglinton Crosstown Light Rail Transit (LRT) Project. LEA Consulting Ltd. is providing Structural Engineering Design Services for the Yonge-Eglinton interchange, Avenue, and Forest Hill (Bathurst) Stations.

The Crosstown project is part of a $8.4 billion investment from the Ontario Government to expand and improve transit in Toronto. The new 19km LRT line will run along Eglinton Avenue, separated from regular traffic and will include a 10km underground stretch with 15 stations and 10 surface stops less than 1km apart. The successful completion of this project will provide commuters with a fast, reliable, convenient, comfortable, and accessible transit solution and will relieve congestion and gridlock on surface roads.

Since each station along the Eglinton stretch has a unique set of challenges, LEA Consulting Ltd. is working in close collaboration with the interdisciplinary teams from CTS to employ innovative structural design solutions with consideration for existing design and required design principles developed by Metrolinx. The Forest Hill station will use a “cut-and-cover” construction method, which will allow for continuous flow of traffic during construction. Avenue Road Station will be a “mined” station, constructed by  “Sequential Excavation Method” because of the high depth of the station box, whereas its entrances will be constructed using the conventional cut-and-cover technique. At the Yonge-Eglinton interchange station, the new LRT station box will be built directly below the existing subway tracks, requiring a complex and remarkable structure. The full LRT line is estimated to be completed in 2021.

The successful completion of this project will be a major accomplishment for LEA Consulting Ltd. as it is the largest transit expansion in Toronto’s history.
