Travelers who use I-5 in Lewis County are invited to provide input using WSDOT’s online open house

LEWIS COUNTY – Future improvements and investments on Interstate 5 between the Harrison Avenue interchange in northern Lewis County and the Grand Mound interchange in southern Thurston County are the focus of an online open house.

Beginning Friday, March 17, the Washington State Department of Transportation invites people who use I-5 in the area to participate in an online open house to provide feedback on the interstate's future.

North Lewis County is a major transportation hub that connects the robust western Washington economy between Vancouver and Olympia. Due to current growth in this area, congestion during weekday peak commute times (typically 6-9 a.m. and 4-6 p.m. Monday through Thursday and 12-2 p.m. on Fridays) has increased, causing significant backups and delays as well as conflicts between travelers sharing the road with freight truck traffic.

Transportation corridor study

With anticipated future growth in this area, WSDOT is studying the corridor to reduce congestion and identify safety and mobility improvements that will mutually benefit local communities and businesses.

The study will also focus on addressing gaps in active transportation including facilities for people who walk or roll, access to public transit, vehicle traffic pain points and ADA compliance.

Virtual open house information

Information about the project is available through the online open house beginning Friday, March 17. Attendees can view the study area and provide their feedback through Friday, March 31.

Slow down – lives are on the line. 

In 2023, speeding continued to be a top reason for work zone crashes.

Even one life lost is too many.

Fatal work zone crashes doubled in 2023 - Washington had 10 fatal work zone crashes on state roads.

It's in EVERYONE’S best interest.

95% of people hurt in work zones are drivers, their passengers or passing pedestrians, not just our road crews.
