Alaskan Way Viaduct Replacement Program and Seattle area projects
Spring 2014 project updates
12-inch natural gas main relocation project
During the week of July 15, 2013, PSE's contractors began laying pipe on Madison Street in Seattle. PSE's natural gas pipeline relocation work is in preparation for WSDOT's Alaskan Way Viaduct replacement program.
- Sidewalk restoration along the project route began the week of March 17, 2014. Brick restoration in Occidental Park is expected to take place this spring, we will notify nearby businesses as the restoration schedule is developed.
- PSE’s natural gas contractor, Michels Corporation, completed installation of the new pipeline (see project route) in late September 2013. Work to relocate the pipeline began in early July 2013.
- PSE’s natural gas contractor, InfraSource, will be conducting remediation activities for distribution pipelines in downtown Seattle through 2014.
- In coordination with the Seattle First Hill Streetcar Project, PSE relocated a segment of existing 2-inch natural gas line along S Jackson Street between Second and Third avenues (see map). This work was completed in April 2013.
In conjunction with Washington State Department of Transportation’s (WSDOT) Alaskan Way Viaduct Replacement Program and several other Seattle-area transportation projects, Puget Sound Energy plans to relocate, reconfigure and otherwise protect segments of the existing natural gas pipeline in areas of downtown Seattle to ensure continued public safety and customer reliability. On July 30, 2013, boring of the new SR 99 tunnel began.
The Alaskan Way Viaduct Replacement Program, Elliott Bay Seawall Project and Waterfront Seattle Project are collectively the largest set of associated projects to take place in the Puget Sound region in several decades. Additionally, there are six other Seattle-area transportation projects planned to take place over the next five years; many of these projects require relocation of utilities, including PSE’s natural gas system. These projects are driven by the City of Seattle, Sound Transit, Washington State Department of Transportation, the Port of Seattle and the U.S. Army Corps of Engineers.

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.
