Title

Interstate 680 Express Lanes from State Route 84 to Alcosta Boulevard Project

Description

Initial Study with Mitigated Negative Declaration/Environmental Assessment with Finding of No Significant Impact The California Department of Transportation (Caltrans), in cooperation with the Alameda County Transportation Commission (Alameda CTC), proposes to construct High Occupancy Vehicle/express lanes (HOV/express lanes) on northbound and southbound Interstate 680 (I-680) from State Route 84 (Vallecitos Road) in Alameda County to north of Alcosta Boulevard in Contra Costa County. HOV/express lanes are specially designated freeway lanes that are free for eligible HOVs and also give other vehicles, including single-occupant vehicles (SOVs), the option to pay a toll to use the lane. The proposed project extends for approximately 9 miles along I-680 from post mile (PM) R10.6 to R21.9 in Alameda County and from PM R0.0 to R1.1 in Contra Costa County. The new HOV/express lanes would pass in or near the cities of Pleasanton, Dublin, and San Ramon, and the community of Sunol. This is to advise you that a finding of No Significant Impact (FONSI) has been made for this project by the California Department of Transportation as assigned by the Federal Highway Administration pursuant to 23 USC 327. A copy of the FONSI and the attached Environmental Assessment can be obtained from the California Department of Transportation office located at the above address.
