Realization of a two-kilometre tunnel starting east of Barnet Highway in Port Moody to south of Kemsley Avenue in Coquitlam. The tunnel will link Burnaby, Port Moody and Coquitlam to the existing SkyTrain line serving Metro Vancouver.
The soils consist of tills, glacial outwash, glaciomarine and ice contact deposits, collectively known as the Coquitlam Drift and Vashon Drift. The bored tunnels will also encounter Quadra Sand. Boulders may also be present along the alignment. Vashon Drift boulders can be expected to consist principally of granitic rocks.
