Toll Facilities

FasTrak lets customers pay their toll electronically on the I-15 Express Lanes and South Bay Expressway in San Diego County, and any toll road, bridge, or express lane in California bearing the FasTrak logo.

To use FasTrak on a toll road or bridge, drivers must have a prepaid FasTrak account and a transponder properly mounted on their windshield. The correct toll is automatically deducted from a prepaid account.
