Didn’t have cash for payment while traveling South Bay Expressway? Pay-by-Plate is the easy way to pay your toll if you don’t have a FasTrak account and didn’t pay by cash or credit card at the toll plaza or at one of our automated cash or credit card machines. You can use our Pay-by-Plate payment option on this Web site, by bringing in or mailing your payment to our offices at 1129 La Media Road, San Diego, CA 92154 or by calling (619) 661-7070 during normal business hours. Please note that the Pay-by-Plate toll schedule is $2 higher than using our automated cash or credit card machines and that if your Pay-by-Plate toll payment is not received within four business days by any of the options listed, there is a $60 minimum penalty.  Click here to Pay-by-Plate.

Important Information about our Customer Service Center

In observance of Thanksgiving the Customer Service Center will be closed for both phone and walk-in customers on Thursday and Friday, November 26 and 27 . We will be open during normal business hours and will be happy to assist with inquiries on the next business day, Monday, November 30. 

Cash-paying customers should also note that the Otay Mesa Toll Plaza will not have toll attendants on duty. Travelers should be prepared to use the automated cash and credit card machines to pay the toll - exact change is required. Please plan accordingly.

We apologize for any inconvenience.
