Express lanes are designated lanes that can be used during heavy traffic to bypass congestion. Express lanes are usually located on the far-left side of select major freeway corridors (described below) and are indicated with white text on the pavement and electronic signage above the roadway.
Hours And Operations
The I-80 Express Lanes operate 5 am - 8 pm seven days a week. All other Bay Area Express Lanes operate 5 am - 8 pm Monday- Friday.
Cost and Methods of Payment
Carpools and motorcycles can use express lanes toll free or at a discount. Solo drivers can also use express lanes by paying a fee. The toll is variable, depending on real-time traffic conditions, and is displayed on overhead signs.
All vehicles must have a valid FasTrak toll tag to use express lanes during tolling (operating) hours.
Eligible low-income residents may qualify for discounted tolls on I-80 and I-880 Express Lanes. Apply for the Express Lanes START discount.

Using Express Lanes
Please use the following tips to avoid common mistakes when traveling in Bay Area Express Lanes.
You must only enter and exit express lanes at dashed or broken lines on the roadway.
Some highway exits may not be available when driving in an express lane. Check roadside signs for details.
For example, on Westbound I-580, you must leave the express lane before Hacienda if you want to exit at Dougherty or to access I-680. On Eastbound I-580, it is recommended that you do not enter the express lane if you need to exit at Santa Rita or Fallon/El Charro.
Do not cross the double white lines to enter or leave an express lane. Crossing them is a traffic violation.
