Express Lanes

Express Lanes increase the efficiency of our transportation system for commuters, transit and freight, by taking advantage of existing capacity to reduce congestion and improve air quality.  Express Lanes give solo drivers the option to pay a toll for access into the HOV lane, when there is excess capacity. Carpools, vanpools, motorcycles, buses and eligible zero and low-emission vehicles continue to use the lanes for free.

Alameda County is home to two express lane corridors, as authorized under California Assembly Bill (AB) 2032, which was signed into law in 2004: I-680 and I-580. These are part of a larger Regional Express Lanes Network in development by the Metropolitan Transportation Commission (MTC) and its partners, including Alameda CTC. Upon completion in 2035, the Bay Area will have 550 miles of express lanes operated by Alameda CTC, MTC, and the Valley Transportation Authority (VTA), and in collaboration with the Contra Costa Transportation Authority and the Solano Transportation Authority.

I-680 Express Lane

Located along a 14-mile stretch of southbound I-680 from State Route 84 south of Pleasanton to State Route 237 in Milpitas, the I-680 Southbound Express Lane has been in operation since September 2010. A northbound express lane along this same corridor is in the environmental documentation phase, and will move into the design phase when funding becomes available.

I-580 Express Lanes

The I-580 Express Lanes project spans approximately eleven miles from Hacienda Drive in Pleasanton to Greenville Road in Livermore in the eastbound direction, and approximately fourteen miles from Greenville Road to San Ramon Road/Foothill Road in Dublin in the westbound direction. Civil design of the combined project has been completed and construction of the civil elements will be performed under the current I-580 construction contracts. Implementation of the electronic toll system is expected to begin spring 2015, with the new express lanes scheduled to open in fall 2015.
