Construction began in November 2017. We currently anticipate that construction activities, including restoration of the work areas, are anticipated to be completed by the end of 2019. Read more about the current construction progress on the North Metro Natural Gas Pipeline Project

Pipeline installation will include a combination of open trenching and boring. Installation by boring allows us to avoid surface impacts to highways, busy roads and intersections and to reduce traffic disturbance during construction. For additional information regarding pipeline installation methods, see the graphic above.

Prior to the placement of a pipeline into either a trench or a bore, sections of pipe are welded together, inspected by x-ray and encased in a protective coating.

The potential impacts from construction may include:

  • Partial, shoulder or complete road closures
  • Traffic control measures such as flaggers and detour signage
  • Temporary changes to business access
  • Elevated levels of noise during construction and testing of the pipeline
  • Vibration near construction sites

During the project, we will maintain traffic control to allow for a safe construction area, while providing commuters, cyclists and pedestrians with the safest possible routes outside the cone zone.

The project will follow all jurisdictional and agency permitting requirements during construction. Once construction has been completed in an area, work areas will be restored to their preconstruction condition.

Project Communications

The project team will notify area businesses, residents and impacted parties prior to construction activities and required changes to access.

The project team will maintain contact with the public prior to, during and after construction through our website, hotline and email.

Throughout the construction process, our team will provide regular updates via email (subscribe to our North Metro Natural Gas Pipeline Project email list), and on our hotline at 855-244-2356 and on this website.

If you experience any issues related to our construction, we want to hear from you. Please contact us directly at 855-244-2356 or via email at

Please note that construction schedules are subject to change due to inclement weather or other factors.

We apologize in advance for any inconvenience that construction may cause, and we thank you for your patience during the construction process.
