Crews will close up to three northbound and three southbound lanes of Interstate 5 Thursday, Nov. 30, through the morning of Friday, Dec. 1, the Washington State Department of Transportation (WSDOT) announced.

At least two lanes will remain open to traffic as crews continue to prepare the existing South 216th Street bridge for demolition in the coming weeks.

This work is part of the State Route 509 Completion Project. As soon as Dec. 8, the existing South 216th Street bridge will be demolished to make way for a new, wider bridge. Watch the South 216th Street bridge video to learn how WSDOT is replacing the bridge in phases. Photos of construction work are available on the project’s Flickr page.
