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.
