KENNEWICK, Wash. - The Washington Department of Transportation has changed their plans for work on the southbound lanes of the Blue Bridge in the Tri-Cities. The project to replace expansion joints is now scheduled to start Friday at 9:00 pm and last through Wednesday at 5:30 am. Both southbound lanes are scheduled to be closed the entire time. A spokesman says workers hope to stay on schedule throughout the project on the southbound lanes, after facing problems that led to multiple delays on the project in the northbound lanes the last few days.
