The Crosstown LRT Project is a Light Rail Transit Line that will run along Eglinton Avenue between Mount Dennis and Kennedy Station. This 19km corridor will include a 10km underground section between Keel Street and Laird Drive. This section comprises 2 bored running tunnels; 12 stations of which 3 (Laird, Avenue and Oakwood) will be built underground using the SEM method; 12 cross passages connecting the bored running tunnels and 3 emergency exit buildings. Dr. Sauer & Partners performed an initial, detailed inspection of the bored running tunnels, every cross passage and every emergency exit building.
The geology comprises heavily over-consolidated hard plastic glacial till layers, stratified deposits of stiff to hard clays and dense, non‐plastic, silt and sand.
