SANDAG operates tolling on the I-15 Express Lanes and SR 125 Toll Road in the San Diego region using FasTrak®—the statewide toll collection system that allows customers to pay tolls electronically in California. FasTrak users can pay tolls in advance to drive on any toll road, bridge, or express lane in California bearing the FasTrak logo. 

To get started with FasTrak, drivers must set up a prepaid FasTrak account and have a transponder properly mounted on their windshield. The electronic toll collection system automatically deducts the correct toll from a prepaid account, so FasTrak customers don’t need to stop to pay. 

About FasTrak Roads

The I-15 Express Lanes are 20 miles of specially designated highway lanes that give solo drivers who cannot use carpool lanes, the option to pay a per-use toll to use the lanes. The express lanes are free to carpools, vanpools, motorcycles, clean air vehicles, and transit riders with no transponder needed. The express lanes were created to ease demand on regular freeway lanes and provide people who share the ride with a smoother, quicker, and more reliable trip. Solo drivers can use the I-15 Express Lanes by using a transponder connected to a prepaid SANDAG FasTrak account. Toll rates for solo drivers on the I-15 Express Lanes vary between $0.50 and $8.00, depending on the distance traveled and traffic in the lanes. The I-15 Express Lanes span between SR 78 in Escondido and SR 163 in San Diego.  

The SR 125 Toll Road is a 10-mile expressway that uses FasTrak to allow customers to bypass toll plazas without stopping. Toll rates are up to 80% lower for FasTrak account holders than those that pay cash or credit at the time of their trip. SR 125 toll rates vary depending on the distance traveled and if you pay through a SANDAG FasTrak account. The SR 125 Toll Road spans from SR 905 in Otay Mesa north through eastern Chula Vista to SR 54 in Spring Valley.
