We encourage all drivers to travel safely and drive defensively while using South Bay Expressway. The speed limit is posted along the toll road and is 65 mph unless otherwise stated. The Expressway is under surveillance 24/7 and our toll operations team is watching out for your safety by sending out a member of our team as quickly as possible to keep machines and equipment working properly. Don’t forget to look out for the cone zone and slow down! We have our team of roadway and landscape technicians working to keep your drive a smooth and beautiful one.
