Dumbarton Bridge links Palo Alto, East Palo Alto, and Menlo Park on the mid-Peninsula with Newark, Union City, and Fremont in the East Bay.

The current base toll is $6, charged in the westbound direction. Carpool vehicles with 2 or more persons can cross the bridge for $3 on weekdays between 5am - 10am and 3pm - 6pm. FasTrak is accepted for payment. As of March 21, 2020, drivers who don't have FasTrak transponder should drive through the toll gate as toll takers are no longer stationed due to concerns of COVID-19. A "Toll violation" bill would be sent to the vehicle owner by mail, but no penalty (only the toll needs to be paid) would be assessed.

A $0.50 discount is given for FasTrak users making a second toll crossing of the day during weekday commute hours (5-10am and 3-7pm).
