Construction of the Trans Mountain Expansion Project in the Lower Mainland area includes approximately 35 km of pipeline; the expansion of the Burnaby Terminal storage facility and Westridge Marine Terminal; and the tunnel through Burnaby Mountain connecting these facilities. Pipeline construction will include conventional construction techniques, and trenchless techniques for key areas such as the Fraser River crossing and in the Fraser Heights neighbourhood.  In these locations, a horizontal directional drill or direct pipe will be used to minimize impacts and disruption. 

Lower Mainland communities include:

• Langley
• Surrey
• Coquitlam
• Burnaby

Construction information will be updated prior to construction.
