This project replaced a bridge span over eastbound I-90 that was damaged beyond repair by an over-sized truck load on October 31, 2007. The collision forced the closure of the I-90 eastbound lanes and traffic was detoured onto the Easton interchange ramps. WSDOT and the emergency contractor demolished the damaged bridge section and re-opened the eastbound lanes of I-90 within 24 hours of the collision. Secretary of Transportation Paula Hammond challenged WSDOT engineers to “get creative – get this bridge replaced as quickly and effectively as possible.” WSDOT met the challenge and opened the repaired bridge on December 15, within 45 days, facing many obstacles including freezing temperatures, snow storms, and extra traffic on I-90 due to travelers trying to avoid the flooding on I-5 in Chehalis.
WSDOT crews closed the roadway immediately and eastbound I-90 traffic was detoured around the damaged bridge. WSDOT bridge engineers determined the bridge was not safe to travel on or under and quickly decided to demolish the damaged bridge span. The demolition was completed within 24 hours of the initial accident and the eastbound lanes of I-90 were opened to traffic.

Since WSDOT replaced a span of an existing bridge, this work had minimal impacts to the environment.
Partnerships & Cooperation
WSDOT held an open house in Easton to inform the public and share information on how this project will move forward. Residents had the opportunity to ask questions and share their input. Attendees were excited to hear this project was moving forward so quickly.
Because of the importance of restoring the functionality of this interchange to the community, we used emergency contracting procedures. WSDOT will seek compensation from the insurance agency representing the trucking company held liable for the collision.
Total Funding Available: Approximately $525,000
