Description

The Crosstown is a light rail transit line, which is part of the regional transportation plan for the Greater Toronto and Hamilton Area. The project will provide a 19km corridor across Eglinton Avenue, connecting ten stops at grade and 15 stations with a 10km twin-bored tunnel. Dr Sauer & Partners provided detailed design for Oakwood, Avenue, Laird and Leaside stations. A combination of Cut-and-Cover construction for the shafts and mined techniques (SEM) for the tunnels will be utilised. Finite element analyses were carried out to determine structure capacity of linings and trigger values.
