Alaskan Way Viaduct Replacement Program and Seattle area projects
Fall 2014 project updates
12-inch natural gas main relocation project
- Columbia St - PSE and its contractors will work to install IP natural gas main along Columbia St between the Viaduct and Alaskan Way. This work is currently planned to begin during the week of Nov. 3. The project will allow PSE to continue to serve customers at Colman Dock during Seawall construction.
- Under-pier work - PSE and its contractor, InfraSource, are working to install temporary IP natural gas main under the pier between Waterfront Park and Pier 54. When Seawall construction is complete, the natural gas main which serves waterfront customers will return to its original location, in Alaskan Way.
- PSE’s natural gas contractor, Michels Corporation, completed installation of the new pipeline (see project route) in late September 2013. Work began in July 2013.
- PSE’s natural gas contractor, InfraSource, will be conducting remediation activities for distribution pipelines in downtown Seattle through 2014.
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 is working to relocate, reconfigure and otherwise protect segments of natural gas pipeline in areas of downtown Seattle to ensure continued public safety and customer reliability.
The Alaskan Way Viaduct Replacement Program, Waterfront Seattle and Seawall 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 several 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.
PSE is working closely and proactively with all the jurisdictions and agencies to ensure the continued safety and reliability of our existing natural gas system in the area.

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 natural gas systems, where it is metered and delivered through a network of local mains, service lines and, ultimately, to customer homes and businesses.
