Trans Mountain has laid the first of what will be 185 kilometres of new pipe through the Kamloops area as construction of the pipeline twinning project continues through Kamloops.
In an update about construction through Kamloops, the federal Crown corporation said the pipe went into the ground last week and crews continue to be busy working near the airport, in the Lac du Bois grasslands north of the city and in Kenna Cartwright Park.
“While there’s pipe in the ground in some areas, crews continue to prepare the right-of-way for construction in others,” the project update stated.
Crews are preparing to cross under railway tracks near Kamloops Airport using the trenchless construction method of auger boring to minimize impacts. The process involves digging holes on either side of the railway, where a boring machine can then drill horizontally under the tracks. A length of assembled pipe is then threaded through the hole. Conventional pipeline construction will take place on either side of the tracks.
A similar boring process will be used to cross under the Thompson River, a process pegged to take place this month.
Currently, a drill is working to create a crossing under the river, starting at the Mission Flats (south) side and working toward the Kamloops Airport exit, the report stated.
At the airport exit site, pipe will be welded together along a stretch of land called a laydown area and eventually pulled beneath the river back toward the Mission Flats shoreline.
According to the update, the crossing is about 40 metres below the riverbed at the deepest point and doesn’t impact the riverbed.
In Lac du Bois, clearing, brushing and grading is underway to prepare the right-of-way for construction and to provide access to other work areas, while in Kenna Cartwright Park, a marmot den was relocated to a location outside the construction area.
