I-580 Express Lanes To Open Spring 2016 New I-580 Express Lanes will open in early 2016 on east- and westbound I-580 through the Tri-Valley. The I-580 Express Lanes are toll-free for carpools, vanpools, motorcycles, buses, and eligible clean-air vehicles (with a green or white sticker) as long as the vehicle carries a FasTrak® Flex toll tag set to 2 or 3+. Solo drivers can choose to pay a toll using a FasTrak or FasTrak Flex toll tag to access the lanes for a more reliable trip. Getting your FasTrak toll tag and opening an account is easy at www.BayAreaFasTrak.org. Learn more and sign up to receive express lane updates at www.facebook.com/AlamedaCountyExpressLanes.
