What’s happening in your neighborhood

We are replacing 5.5 miles of natural gas lines near Highway 10/Highway 61 and replacing regulator stations and valves in Cottage Grove and St. Paul Park for the South Washington Natural Gas Project. Construction activities will be completed in public rights-of-way and easements on private properties.

Construction began in spring 2021 and is expected to be completed in fall 2022.

This work is our commitment to system revitalization, allowing us to continue to provide you safe, reliable service. It will support community growth and enhance resiliency during extreme weather.

Construction Overview

We will install the natural gas lines in two ways.

  • Open trenching involves digging a trench and placing the line in the trench.
  • Boring uses a bore machine to create an underground pathway through which the line is pulled or drilled.

Before placing natural gas lines into a trench or bore, sections of pipe are welded together and inspected by x-ray. Click here to see a graphic of open trenching and boring construction processes.

We will notify landowners, businesses and residents prior to the start of construction.

  • Between the intersections of 100th Street and Miller Road and of 96th Street and West Point Douglas Road.

Construction and Restoration

During construction, you may notice:

  • Marking of utility lines and utility survey holes.
  • Road and sidewalk closures.
  • Traffic control.
  • Parking restrictions.
  • Potential access changes.
  • Construction noise.

We work to reduce construction-related inconveniences and will temporarily restore work areas following natural gas line installation. Final restoration will occur when conditions allow.
