Fort St. John, B.C.-based Macro Enterprises says that it has commenced construction of a 67-kilometre stretch of the North Montney Mainline.
The $1.4-billion pipeline to connect growing Montney production to North American markets was given the green light by the National Energy Board in May.
Macro is building a portion of the 206-kilometre project in a contract valued at $200 million.
The North Montney Mainline was originally tied to the Pacific NorthWest LNG project, but TransCanada subsidiary NOVA Gas Transmission said it would proceed anyway after proponents walked away from the LNG project last year.
The pipeline is expected to be in service in mid-2019.
