How to use the I-680 express lanes?

The I-680 Southbound express lane requires a FasTrak toll tag for solo drivers. Carpoolers on the I-680 Sunol Express Lane currently do not need a toll tag, but can use the new FasTrak Flex toll tag set to 2 or 3+, or place their standard toll tag in a mylar bag to avoid being charged a toll. Find a carpool and use the lanes toll free! Get a FasTrak Toll Tag.

Who can travel in the I-680 Express Lanes?

ALL USERS MUST HAVE A VALID FASTRAK ACCOUNT TO USE THE EXPRESS LANES

Pays a Toll

Solo Driver with a FasTrak account may pay a toll to travel
  • May carry a valid FasTrak Flex toll tag set to 1, or
  • May carry a valid FasTrak or bumper tag

Travels Tolls Free

Carpools, Clean Air Vehicles with qualifying DMV sticker, Motorcycles, and Transit vehicles may travel toll free under the following conditions:


No toll tag in the vehicle (none required)


Standard FasTrak toll tag placed in mylar bag


FasTrak Flex tag set to 2 or 3+. FasTrak Flex has a switch that allows drivers to designate whether they are driving solo, or are a carpool with 2 or 3+


FasTrak CAV toll tag set to match the number of people in the vehicle

How much does it cost?

The express lane is always free for carpoolers. For solo drivers, 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 can change every 15 minutes. Customers are locked-in to a toll rate controlled by the overhead sign prior to 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.

HELPFUL TIPS

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 the customer check the tag position before each time you travel in the express lane.

Enforcement

A solo driver in the Express Lane without a valid FasTrak® toll tag is in violation of state law and subject to a fine. Law enforcement officers patrol the lane and use visual and electronic means to catch violators. Also, it is a violation for any driver to cross the double solid lines separating the Express Lane from other lanes.

Governance

The I-680 Sunol Express Lane is governed by the Sunol Smart Carpool Lane Joint Powers Authority, and was funded with State, Federal, and local funds. Alameda County’s voter-approved local sales tax Measure B provided nearly half the funding for the Express Lane. Usage of the express lane has increased steadily since inception.

The I-680 Sunol Southbound Express Lane has been in operation since September 20, 2010. Construction of the project involved converting High Occupancy Vehicle (HOV) lanes to High Occupancy Toll (HOT) / express lanes 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.

Alameda CTC formed a partnership with the Federal Highway Administration (FHWA), California Department of Transportation (Caltrans) and the California Highway Patrol (CHP) to develop and implement the I-680 Express Lanes Project. The project, which will construct a new northbound express lane along this same corridor and convert the southbound express lane to continuous access, broke ground in April 2018 and construction is underway.

Environmental Process

A Draft Environmental Impact Report/Environmental Assessment (EIR/EA) was prepared for the I-680 Northbound HOV/express lane project for public circulation beginning in November 2014. The final Environmental Impact Report/Environmental Assessment (EIR/EA) was approved July 2015.
