Bay Area Express Lanes I-680Construction of a portion of the Bay Area Express Lanes on I-680 (between Walnut Creek and San Ramon) has begun and is scheduled to last approximately 15 months. Construction includes installation of variable message signs and overhead toll readers, concrete foundations for overhead freeway sign structures, and laying conduit and fiber optic communications cables for traffic management system communications.
The Metropolitan Transportation Commission (MTC) is scheduling construction work so that it will have minimal impacts on traffic. Construction will mainly occur at night, although there may be occasional activity on the shoulder and on arterial streets adjacent to the highway during the day to complete the communications network. Nighttime construction will typically involve closing one or two highway lanes, depending on the nature of the work.

Express Lanes are specially-designated highway lanes that offer toll-free travel for carpools, vanpools, transit, motorcycles and eligible clean air vehicles. Solo drivers also have the choice to pay a toll to use the lanes for a more reliable trip. The Express Lanes between Walnut Creek and San Ramon will have an open access configuration, similar to HOV lanes.
The I-680 Express Lanes between Walnut Creek and San Ramon are scheduled to open in fall of 2016. For more information, you can visit bayareaexpresslanes.org or email info@bayareaexpresslanes.org to request project updates.
