Bay Area Express Lanes are carpool lanes that are free for carpools, buses, motorcycles and other eligible vehicles. Solo motorists — who choose to pay a toll — can use express lanes, too!
Express lane tolls are collected electronically via FasTrak® - no stopping at toll booths!
Newer Express Lanes, including those that opened in 2020 on I-880 in Alameda County as well as those that opened in 2017 on I-680 between Walnut Creek and San Ramon, and the I-580 Express Lanes through Dublin, Pleasanton and Livermore, require carpoolers to use FasTrak Flex® for toll-free travel.

Standard operating hours for Express Lanes are Monday through Friday from 5 a.m. to 8 p.m.
Overhead electronic signs display the toll rates. As traffic increases, tolls increase. And as traffic decreases, tolls decrease.
Bay Area Express Lanes improve mobility and enhance travel options by:
- Making use of available space in existing carpool lanes to move more people;
- Improving operations in existing carpool lanes through better enforcement and strategies to prevent lane slowdowns;
- Giving everyone the choice to carpool for free or pay for a more reliable trip when it really matters; and
- Filling gaps in the carpool lane system to encourage more carpools, vanpools and buses.
