Construction of the Trans Mountain Expansion Project in the Lower Mainland includes Spread 7 pipeline construction – 35 km of pipeline construction between Langley and Burnaby – as well as the expansion of Burnaby Terminal, Westridge Marine Terminal and construction of the Burnaby Mountain Tunnel.

Lower Mainland communities include:

  • Langley
  • Surrey
  • Coquitlam
  • Burnaby

The contractor responsible for all work in the Lower Mainland is the Kiewit Ledcor Trans Mountain Partnership (KLTP). KLTP was formed specifically to carry out this work and has a proven track record in finding solutions to minimize impacts of construction activities.

Spread 7 Pipeline Construction

The Lower Mainland includes approximately 35 km of pipeline construction extending from 232 Street in Langley to our terminals in Burnaby. Pipeline construction will include conventional construction techniques and trenchless techniques for key areas like the Fraser River crossing, the Salmon River crossing and in the Fraser Heights neighbourhood.

Spread 7 pipeline construction includes:

Burnaby Terminal

Work at Burnaby Terminal includes the removal of one existing storage tank and installation of 14 new storage tanks. Installation of an enhanced stormwater treatment system and relocation of four non-fish-bearing watercourses within the terminal. Additionally, tunnel portal construction for the Burnaby Mountain Tunnel will take place within Burnaby Terminal

Westridge Marine Terminal

Construction activity at Westridge Marine Terminal includes pile driving and other in-water work  on three new shipping berths and a new utility dock for support vessels, as well as a foreshore expansion to accommodate new operations infrastructure and buildings.

Burnaby Mountain Tunnel 

To reduce disruption to our neighbours and existing infrastructure, a 2.6-kilometre tunnel will be built to contain the pipeline connecting Burnaby Terminal and Westridge Marine Terminal. The tunnel will be built from two portals located within our existing terminals using a specifically designed tunnel-boring machine.
