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 and 15 underground stations with a 10km twin-bored tunnel. Dr. G. Sauer & Partners provided detailed design for Laird, Avenue and Oakwood stations. A combination of Cut-and-Cover construction for the shafts and mined technique (SEM) for the tunnels has been utilised. The 24/7 supersvision services provided engineering support, detailed inspection and documentation by a team of eperts for each of the three stations.
