How much does it cost?

The overhead sign states the toll amount to travel to next zone (top line) and the price to travel to the end of the express lane (bottom line). Toll prices vary based on congestion and can change every 5 minutes. Customers are locked-in to a toll rate controlled by the overhead sign prior to the location of entry. The locked-in rate does not change if the price goes up or down while the customer is still in the express lane. If you exit prior to the last zone, you may be charged a toll between the price on the top line and price on the bottom line.

Helpful tips

Stay In The Lane – The Toll Stays The Same!

A toll is assigned based on the first and last location at which the vehicle was detected. If you leave and then re-enter an express lane, FasTrak will charge you a single toll as though you travelled continuously in the lane. It is unlikely that weaving in and out of the express lane will decrease your toll.

Know Before You Go

Carpoolers and those eligible to use carpool lanes (motorcycles, vanpools and transit buses) must have a FasTrak Flex (switchable) toll tag to use the lanes toll-free.

Who Needs A Fastrak Toll Tag?

Everyone using the I-680 Express lanes during operating hours (M-F 5am-8pm) must carry a valid toll tag properly mounted in the vehicle.

Set It But Don’t Forget It

If your flex tag is detected in different positions during your express lane trip, you will be charged based on the lowest occupancy that is detected.

For example, switching the Flex tag setting from 1 to 2 after you have entered the express lane could still result in a toll charge for the entire distance traveled. We recommend checking the tag position before each time you travel in the express lane.

The I-680 Sunol Southbound Express Lane was first opened on September 20, 2010 when the High Occupancy Vehicle (HOV) lane was converted to a High Occupancy Toll (HOT) / express lane along southbound I-680 from south of State Route 84 to north of State Route 237. The conversion required additional roadway widening and installation of tolling equipment throughout the project corridor.

Beginning in 2018, work began to construct a new northbound express lane on I-680 between Auto Mall Parkway and SR-84 and to change the access configuration of the southbound lane to allow drivers to enter and exit more freely. Tolling operations were suspended on the southbound lane in August 2020 to allow for construction. The new northbound lane and the southbound lane were opened to high-occupancy vehicle traffic in October 2020. Tolling operations on the northbound and southbound I-680 Sunol Express Lanes resumed on March 31, 2023.
