SR 16 Study

SR 16 – Tacoma Narrows Bridge to SR 3 Congestion Study

Please join us at one of our open houses in your neighborhood!

WSDOT is hosting open houses in Gig Harbor and Port Orchard to discuss updates to the SR 16 – Tacoma Narrows Bridge to SR 3 Congestion Study. Community members will have the opportunity to learn more about the study’s purpose, key congestion issues along the corridor, outcomes from the public opinion survey and potential strategies to help reduce congestion along the corridor.

Study Purpose

SR 16 Tacoma Narrows Bridge to SR 3 Congestion Study Map

In this study, WSDOT will examine 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 project will investigate 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.

Needs & Benefits

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 short-, mid-, and long-term strategies to improve travel.

The strategies to improve travel in the corridor could include:

  • Operational improvements
  • Intelligent Transportation System (ITS) improvements
  • Transportation demand management
  • Transit, freight, bicycle, or pedestrian improvements
  • Enhancements to roadway configuration
  • Education and enforcement


WSDOT, working with stakeholders, will identify congested areas along the SR 16 corridor and recommend suitable strategies to meet current and future travel needs. This study is anticipated to be completed during winter 2018.

The End Result

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 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.
