SR 302 Study

SR 302 - Elgin Clifton Rd to SR 16 - Corridor Study

Why is WSDOT studying State Route 302?

WSDOT is studying SR 302 because it is an important east-west link for Key Peninsula communities to Gig Harbor as well as Tacoma and other parts of Washington. Economic development puts demands on the highway system creating concerns about safety and congestion.

To address these concerns, WSDOT is studying the SR 302 corridor from Key Peninsula Highway to SR 16. The study evaluates the environmental impacts of:

  • creating a new corridor, and  
  • improving the existing corridor by providing improved mobility and enhanced safety.

The environmental impacts taken into consideration include air quality, fish and aquatic resource, water resource, wetland, soil, wildlife and terrestrial habitat, hazardous materials, historic and cultural resource, land use, noise, energy, section 4(f), social/economic and environmental justice, and visual quality impacts.

No preferred alternative has been selected. Currently, WSDOT is considering four alternatives:

  • Alternative 4 - Uses existing SR 302 and a new alignment in the vicinity of 144th St. NW out to Burley Lagoon, constructs a new bridge across Burley Lagoon, and matches into and improves existing 144th St. NW out to a new SR 16 interchange.
  • Alternative 6 - Uses existing SR 302 to 144th St., where a new alignment would begin and head northeast toward Pine Rd.  The route follows Pine Rd. to the SR 302 Spur to an improved SR 302 Spur/SR 16 intersection.
  • Alternative 7 - Uses existing SR 302 then travels north on 118th Ave. to Pine Rd. to the intersection of Bethel-Burley Rd. The alignment would then head southeast on the SR 302 Spur to an improved SR 302 Spur/SR 16 intersection.
  • Alternative 10 - Uses existing SR 302 to approximately 154th St. in the vicinity of 82nd Ave. and out to Burley Lagoon, to construct a new bridge across the lagoon. The new alignment would connect into existing 154th St. out to a new SR 16 interchange.

The End Result

The end result of the environmental impact statement process will be a preferred alternative that meets the transportation needs and fulfills all federal and state environmental laws.  

Project Benefits

The SR 302 Corridor Study EIS will determine the potential environmental impacts of future projects which will help alleviate congestion and improve the safety of the traveling public.

What is the project timeline?

This study began in 2007. Current funding carried it through 2012:

  • 2007 - WSDOT began evaluating existing conditions and studying traffic patterns. Briefings with more than 30 stakeholder groups were conducted. Public meetings were held to understand what the concerns are, and to gather information about existing traffic conditions on the route.
  • 2008 - Preliminary environmental work was conducted, a travel model was developed for the study, and the first of two alternatives screening exercises occurred.
  • 2009 - A second alternatives screening exercise was conducted, notice of intent to prepare an Environmental Impact Statement was issued and WSDOT held an agency and public scoping comment period.
  • 2010 to 2012 – WSDOT conducted detailed environmental and engineering work to be included in the discipline reports, an important component of the environmental document. 

Reports

As funding becomes available, the next steps are to finalize the discipline reports and compile the studies into draft and final EIS documents for public and agency review. The ultimate goal is to finalize these documents by considering both the environmental studies and the comments received to reach a well researched decision about a preferred alternative. 

Financial Information

WSDOT has partially funded the study. Conclusion of this study, including design and construction, relies on available funding.
