Puget Sound Energy natural gas pipeline project

Bellevue Braids/Lake Hills Connector

Winter 2009-10 project completion
  • Puget Sound Energy has completed construction of the new $16.4 million natural gas pipeline in downtown Bellevue
  • Construction of the natural gas pipeline was completed in February 2009, while construction to replace traffic loops and finish overlay work was completed in February 2010
Project overview

PSE has completed construction of a new natural gas pipeline in downtown Bellevue to provide uninterrupted service to existing customers and to accommodate projected demand for natural gas. We installed approximately 1.9 miles of 16-inch natural gas line from 140th Avenue SE to SE 8th Street, and linked it to another segment of 1.6 miles of 12-inch natural gas line that runs along 112th Ave SE and 110th Ave NE. The new main replaced an existing main that will be temporarily taken out of service during construction of a Washington State Department of Transportation (WSDOT) I-405 road improvement project. Due to future natural gas requirements, installing a larger pipeline alongside the WSDOT construction project was practical and economical.

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.
