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.
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.
The Interstate I-680 (I-680) Northbound high occupancy vehicle (HOV)/Express Lane project proposes to add a HOV/express lane in the northbound direction on I-680 from south of State Route 237 (SR 237) to north of SR 84 (approximately 15 miles), within Santa Clara and Alameda Counties in and near the cities of Milpitas, Fremont, Pleasanton, and the community of Sunol. The project is being proposed to increase the efficiency of the transportation system by expanding and optimizing freeway capacity to reduce congestion and accommodate existing and future travel demands.
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 is being 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.
