28th Street and 

Colorado Avenue 

Natural Gas Project


We will replace 400 feet of natural gas line in the intersection of 28th Street and Colorado Avenue. This work allows us to continue to provide safe, reliable natural gas service and enhances system resiliency during extreme weather.

How it affects you

During work, you may notice:

  • Marking of utility lines and utility survey holes.
  • Road and sidewalk closures.
  • Traffic control.
  • Temporary changes to access.
  • Construction noise.

We install natural gas line by open trenching and boring.

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

We are committed to maintaining a safe working environment in your community. For your safety and the safety of our crews, remember these tips:

  • Watch for construction crews and equipment.
  • Do not enter construction areas.
  • Obey signage and directions from crews.
  • Reduce speeds while traveling.
  • Observe parking restrictions.
  • Remain flexible as work progresses and work areas change.

We’ll restore work areas to preconstruction conditions as weather allows. Work areas may be left temporarily restored after construction until we can complete final restoration.


Construction will start in spring 2024 and is expected to continue through summer 2024.

Schedules are subject to change.
