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 has been utilised. Finite element analyses were carried out to determine structure capacity of linings and trigger values. Fibre reinforced sprayed concrete was used for temporary and permanent linings.
