1/ This is a miles-long clean-up scene. The spill has left oil across all northbound lanes and has soaked into the surface. It means there are several miles of slippery roadway. We're working to reopen at least one lane of northbound I-5 as soon as possible.

2/ However, it's likely we won't see all lanes reopened until early Thursday morning. Please continue to avoid the area, cancel discretionary travel,or take alternative routes. #Centralia
