Puget Sound Energy utility relocation project

Olympia 18th Avenue utility relocation project

Summer 2011 project completion
  • We completed the relocation of our four-inch natural gas line in mid March 2011
  • We completed power pole replacement in early May 2011
  • Relocation of the six-inch natural gas line was completed in mid August 2011
Project overview

The city of Olympia’s 18th Avenue Sewer Main and Roadway Improvement project required Puget Sound Energy to relocate our natural gas lines and replace our electric transmission and distribution poles along 18th Avenue Southeast to accommodate storm water and roadway improvements.

PSE’s project included:

  • Relocating and upgrading one-half mile of our six-inch natural gas line, which runs between Craig Road Southeast and Boulevard Road Southeast on 18th Avenue Southeast, to an eight-inch natural gas line
  • Relocating 450 feet of our four-inch natural gas line between Allen Road Southeast and Amhurst Street Southeast
  • Replacing 16 distribution and transmission poles on the north side of 18th Avenue Southeast between Redwood Place Southeast and Boulevard Road Southeast

This work was performed during daytime hours, Monday – Saturday. Traffic control procedures were in effect with lane closures and alternating traffic.

Test your natural gas knowledge
by taking this short survey.

How does natural gas get to my home or business?

Natural gas is a fossil fuel composed almost entirely of methane. Interstate pipelines transport natural gas to regional utility natural gas systems, where it is metered and delivered through a network of local mains, service lines and, ultimately, to customer homes and businesses. More than one-third of all Washington state households and businesses use natural gas.

What is a transmission line?

Transmission lines are key elements in the electrical distribution system. The lines safely transport high voltage electricity from power generation sources like dams and wind generating facilities to substations in local communities. Transmission normally takes place at voltages of 55 kV and higher.

Committed to keeping you informed

PSE will continue to provide updates to the community. We will notify residents and businesses near the project area when construction will occur. We aim to complete the work with as little disruption as possible.
