OLYMPIA – Washington state is earthquake country. As part of an ongoing effort to minimize damage when a quake strikes, crews working for the Washington State Department of Transportation will begin a new construction project to help protect Interstate 5 in Olympia.

This work will strengthen the I-5/Pacific Avenue overpass. Crews will install steel jackets on four separate bridge columns in order to help withstand quakes.

The work will require reduced lanes on Pacific Avenue approaching I-5. One sidewalk will remain open. The work will not affect I-5 or the Pacific Avenue ramps.

The project will begin as early as Monday, Jan. 6. The work is scheduled to be complete by early spring.

Visit the Thurston County construction and travel updates web page to get advance notification for construction-related changes to Pacific Avenue. WSDOT also provides email updates for major roadwork on state highways in Thurston County. Real-time traveler information is available from the WSDOT app and by following the WSDOT regional Twitter feed.
