Construction in the Yellowhead region of Alberta includes work at pump stations, pipeline construction and trenchless crossings using horizontal directional drilling (HDD). Recently, Midwest Pipelines remobilized following spring break-up and has started right-of-way pipeline construction in the Edson area.

To prepare for construction elsewhere in the region, access roads and temporary approaches are being built. Clearing of the right-of-way is currently on hold to allow for bird migration but will continue in the coming months.

Mainline construction in the Town of Edson


Progress is being made at two major HDDs in the Yellowhead region under McLeod River and Hardisty Creek. In July, the entry and exit sites for the crossings were set up, including the installation of sound walls to reduce noise disruption for adjacent neighbours. Drilling is currently underway at both sites.

Wolf Pump Station


Work has also been progressing at the Gainford, Wolf, Edson and Hinton Pump Stations. On site, excavation is underway to accommodate new piping and the installation of an additional pump station at each site. Pile driving will also take place at each pump station to provide support for the new infrastructure being built.

At the Edson Pump Station, installation of rebar for the foundations is being done in anticipation for the upcoming concrete pour.

At Gainford and Hinton, sump tank excavation is also progressing.

Pipeline construction in the Yellowhead region is being done by Midwest Pipelines, and pump station construction is being done by Cord. If you’re interested in jobs or procurement opportunities, click here for more information.
