SR 16 Study

SR 16 – Tacoma Narrows Bridge to SR 3 Congestion Study

After working with stakeholders and taking public feedback, WSDOT has examined congested areas along the SR 16 corridor. WSDOT is in the process of identifying strategies to meet current and future travel needs. The study will conclude with a report outlining strategies to improve travel in the corridor. The report will guide WSDOT moving forward in identifying future solutions. WSDOT anticipates completing this study during spring 2018.

Study Purpose

WSDOT examined traffic congestion along State Route 16 between the Tacoma Narrows Bridge and Gorst, as well as portions of SR 3 and SR 304 in Pierce and Kitsap counties. The study investigated how to manage current and future travel in the corridor using strategies identified through the Practical Solutions planning approach. Practical Solutions is a performance-based approach to transportation decision-making.

The end result 

The study will summarize existing and future conditions in the corridor -- such as congested areas -- based on data and stakeholder input. This study will propose near-, mid-, and long-term strategies to improve travel.

The study will conclude with a range of strategies to improve travel in the corridor. The study report with recommended strategies will guide WSDOT moving forward in identifying future solutions.

The strategies to improve travel in the corridor could include:

  • Operational improvements
  • "Smart highway" devices that help WSDOT manage traffic and relay roadway information to the public such as variable-message signs and other Intelligent Transportation System (ITS) improvements
  • Encourage carpools and vanpools to help encourage people from not driving alone during peak periods and other transportation demand management strategies. 
  • Transit, freight, bicycle, or pedestrian improvements
  • Enhancements to roadway configuration
  • Education and enforcement
     

Funding

The SR 16, Tacoma Narrows Bridge to SR 3, Congestion Study is funded by Connecting Washington, a funding package passed by the Washington Legislature in 2015.
