North Lewis County Industrial Access Transportation Study online open house

English  |  Español


Like many areas in Washington, North Lewis County’s local roads are shared with regional freight traffic. Congestion is common because these roads are not designed to handle the number of vehicles traveling within and throughout the area. To mutually improve mobility and industrial access, we are studying opportunities to improve the performance and safety of streets near the I-5/Harrison Avenue interchange (Exit 82) to better serve the community. To begin the assessment, we are reviewing the existing environmental resources and traffic conditions to narrow a wide range of potential projects down to one viable set of recommended improvements. This online open house provides a summary of our initial findings and asks for your comments on possible improvements or new projects that meet the purpose and need of the study.

Purpose and Need of the Study

The purpose of the North Lewis County Industrial Access Transportation Study is to address current conflicts between freight traffic and multimodal travelers near the Harrison Avenue interchange at I-5 (Exit 82). The project team is taking a holistic view of transportation in North Lewis County and identifying potential solutions to improve travel in the area.


The Legislature assigned $1 million from the Connecting Washington transportation package to conduct the study. As directed by the Legislature, we are identifying opportunities to improve access to industrially zoned properties in the area while determining the feasibility of constructing the I-5/North Lewis County interchange project.

Stakeholder Team

We are working alongside a team of local stakeholders who are providing input at key milestones of the study. Their recommendations will refine the suggested improvements and ensure support from local agencies. The Stakeholder Team includes staff from the:

  • Federal Highway Administration
  • Washington State Department of Transportation
  • Thurston Regional Planning Council
  • Cowlitz-Wahkiakum Council of Governments
  • Twin Transit
  • Economic Alliance of Lewis County
  • Thurston County
  • Lewis County
  • Port of Centralia
  • City of Centralia
  • Centralia College

The Stakeholder Team is being supported by a separate team of planning, design, and environmental staff from state and local agencies that are adding additional technical depth and recommending potential solutions to resolve transportation issues identified for the group. Both the Stakeholder Team and this core technical team will help refine the transportation improvements under consideration during the study.

How to Participate

Your input will help identify the preferred set of improvements we select in the study. Please share your opinions, concerns, and preferences with us in this open house. If something comes to mind after the open house has finished, please feel free to submit your comment on the project website. Your perspective and feedback will help us understand the community and shape the future of transportation.
