WSDOT to begin three-year culvert removal project on I-5 in Whatcom County

The Washington State Department of Transportation (WSDOT) initiates a crucial culvert removal project along I-5, with traffic impacts starting this week due to overnight lane closures. From April 30, drivers can expect single-lane closures from 8 p. m. to 5 a. m.

until early June, transitioning to temporary two-lane bypass roads during the summer months. This initiative follows a 2013 federal court ruling requiring the state to eliminate culverts that block salmon, bull trout, and steelhead habitats, highlighting the legal impetus behind the project. WSDOT plans to replace 17 barriers with 10 new structures, which is essential for restoring fish migration routes and enhancing biodiversity. The project not only addresses environmental concerns but also reflects a commitment to sustainable infrastructure. Local communities are likely to experience both traffic disruptions and long-term ecological benefits.

Construction is expected to extend through 2027, marking a significant investment in both transportation and environmental health.
