Coastal GasLink will be built using the safest, least disruptive construction methods that have been developed over the past three-quarters of a century. The 670-kilometre Project is divided into eight construction sections and can take several weeks to construct, dependent on terrain and weather conditions. Construction is being carried out by our highly qualified prime contractors.

Various pipeline construction activities will be shared with stakeholders through notifications. These include:


Blasting IconBlasting:
Blasting is done in the clearing phase of construction to break rock for excavation. All blasting activities are done in accordance with provincial and federal regulations.
Burning IconBurning:
As the right-of-way is cleared, timber is saved to be processed by the forest industry. Vegetation that is not suitable for repurposing, such as branches and shrubs, are burned in approved areas and on days permitted by local forestry burning rules in compliance with the provincial regulations.

Traffic Interruptions IconTraffic interruptions:
Construction activities that interfere with traffic fall within our notification guidelines.

The right-of-way

The Coastal GasLink pipeline project right-of-way is approximately 45 metres wide during construction, and will be cleared of trees and brush.

Once construction is complete, the right-of-way will be maintained at approximately 32 metres in width to allow for operation, and to keep the area above the pipe clear of trees and branches. The width of the permanent right-of-way may vary depending on local requirements.

It is anticipated that the proposed pipeline will be buried under the ground for all of its approximately 670-kilometre length, except at specific locations such as fenced valve sites and compression stations.

The surface of the right-of-way is disturbed during construction to prepare a safe work surface and allow for digging the pipe trench. On agricultural land, topsoil is conserved prior to trenching to maintain land capability.

Coastal GasLink will take measures during and after construction to manage the potential for invasive plants and weeds.
