After two years of work, construction on the Trans Mountain Pipeline expansion is complete in the Edmonton region.

Trans Mountain Corp., a federal Crown corporation, announced Tuesday the work to replace the existing line that runs through several south Edmonton neighbourhoods had wrapped up.

The new lines run nearly 50 kilometres from Trans Mountain’s Edmonton Terminal in Sherwood Park to the Acheson Industrial area west of the city.

Much of the new pipeline was laid along the Transportation Utility Corridor in which the south leg of Anthony Henday Drive is located.

The project included complicated crossings under roads and the North Saskatchewan River.

Trans Mountain used a trenchless construction technique to minimize the need for closing major roads, as well as horizontal directional drilling (HDD.)

Construction began in December 2019 and included the installation of 48,762 metres of pipe, 14 horizontal directional drills, and 472 tie-ins, or work to connect together different sections of pipe to form the single line.

Trans Mountain said the project took 1.5 million person-hours of work to complete. SA Energy was the contractor leading the pipeline expansion work in the Edmonton region until early 2021, when the contract was then awarded to Midwest Pipelines for completion.
