The I-680 Express Lane opened on September 20, 2010, following a two- year project to convert it from a pre-existing 14-mile I-680 southbound carpool lane, from Highway 84 in Alameda County to Highway 237 in Santa Clara County.

The Express Lane has three entry and exit points and is separated from general-purpose lanes by new double-solid striping. Electronic signs installed overhead indicate entry and exit points and also the current toll price.

Solo drivers who want a more reliable trip on southbound I-680 need to obtain and mount a FasTrak® toll tag on their windshields. They are charged a toll each time they choose to use the Express Lane. Small two-axle commercial vehicles equipped with FasTrak® can also use the lanes. Carpool vehicles with two or more people, motorcycles, transit buses and eligible hybrids continue to use the lane for free and are not required to have a toll tag.

FasTrak® is the same electronic toll collection system used on Bay Area bridges and throughout California. With FasTrak®, tolls are collected electronically at highway speeds – no tollbooths or traffic gates, and no need to slow down or stop to pay the toll.

Here’s how it works. Vehicles with a FasTrak® toll tag can enter and exit the I-680 Express Lanes at three clearly designated points. Solo drivers entering the lanes see an overhead electronic sign displaying the current toll. When the vehicle passes under a reader, the FasTrak® toll tag is read and the correct toll is automatically deducted from the driver’s prepaid FasTrak® account. Again, carpoolers, motorcyclists and eligible hybrids can se the lane for free.

Carpoolers need to put their FasTrak® toll tag in a Mylar bag to avoid being charged. If you have misplaced your Mylar bag, call the FasTrak Customer Service Center at 877-229-8655 (877-BAY-TOLL), and they will mail you a replacement bag.
