Shoulder Work

Workers and equipment are operating on the shoulder; stay in your lane and slow down.

Construction or maintenance work is taking place on the road shoulder, but the travel lanes remain open. Stay alert for workers, equipment, and vehicles entering or leaving the shoulder, reduce speed, and move over a lane when it is safe to provide additional clearance.
