Interstate 680 (I-680) is a north–south

Of the above names, only the name Sinclair Freeway for its designated portion usually appears on maps, and the other portions on maps are always unnamed, referred to as simply I-680.[8]
I-680 is part of the California Freeway and Expressway System[10] and is part of the National Highway System,[11] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration (FHWA).[12] I-680 is eligible to be included in the State Scenic Highway System from the Santa Clara–Alameda county line to SR 24 in Walnut Creek[13] but is only a scenic route from Mission Boulevard to the Contra Costa county line and from the Alameda county line to SR 24;[14] this means that those portions are substantial sections of highway passing through a "memorable landscape" with no "visual intrusions", where the potential designation has gained popular favor with the community.[15]
Tolls
Express lanes
There are two sections of
HOT lanes then opened in October 2017 in both directions on the portion from slightly south of Alcosta Boulevard near the Alameda–Contra Costa line to Rudgear Road in Walnut Creek.[18] On August 20, 2021, the southbound HOT lanes were extended north from Rudgear Road to Marina Vista Boulevard in Martinez.[19]
As of August 2022[update], the HOT lanes' hours of operation is weekdays between 5:00 am and 8:00 pm. Solo drivers are tolled using a congestion pricing system based on the real-time levels of traffic. Carpools, motorcycles, and clean air vehicles with two or more people are not charged. For clean-air vehicles with a solo driver, 50 percent of the posted toll is charged.[20][17] All tolls are collected using an open road tolling system, and therefore there are no toll booths to receive cash. Each vehicle is required to carry either a FasTrak Flex or CAV (Clean Air Vehicle) transponder, with its switch set to indicate the number of the vehicle's occupants (one, two, three, or more). Solo drivers may also use the FasTrak standard tag without the switch.[20][17] Drivers without any FasTrak tag will be assessed a toll violation regardless of whether they qualified for free.[21]
As of 2020, there are environmental studies to extend the northbound toll lanes from Livorna Road to the southern beginning in Martinez, as well as closing the nine-mile express lane gap between Sunol and San Ramon. Neither have began construction, nor are there any near plans to do so.[22][23]
