Express Lane Project History

Alameda CTC formed a partnership with the Federal Highway Administration (FHWA), California Department of Transportation (Caltrans) and the California Highway Patrol (CHP) to develop and implement the I-580 Express Lanes Project. Electronic toll system installation began Spring 2015 and the new express lanes opened in February 2016. See the fact sheet and construction photographs from June 2015.

The express lanes allow HOVs to travel without cost and give solo drivers the option to pay to use the lanes. The project area is from west of Hopyard Road/Dougherty Road to east of Greenville Road in Dublin, Pleasanton, and Livermore, Alameda County. Caltrans approved the Initial Study/Environmental Assessment in March 2014.

Environmental Process

Pursuant to the California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA), Caltrans, in cooperation with the Alameda CTC, has studied the environmental effects of this project. These studies show that the project would not significantly affect of the quality of the environment. The report that discusses these findings is called an Initial Study with Proposed Negative Declaration/ Environmental Assessment (IS/EA).

The IS/EA is available for review online at www.dot.ca.gov/dist4/envdocs.htm and may be downloaded here:

A public meeting about the I-580 Express Lanes project was held on January 22, 2014 at the Dublin Unified School District Board Room in Dublin, CA. See the public meeting notice. Prior to that, a public information meeting was held at the Dublin Civic Center on May 14, 2013. See the public meeting notice

A noise study was conducted, and no new sound walls are proposed. Project-level conformity analysis shows that the project will conform to the State Implementation Plan, including localized impact analysis with interagency consultation for carbon monoxide (CO) and particulate matter (PM2.5) required by 40 CFR 93.116 and 93.123. This project is considered a Project of Concern regarding particulate matter (PM2.5) as defined in 40 CFR 93.123(b)(1) and the 2006 U.S. EPA Particulate Matter Hot Spot Analysis Guidance. A detailed PM2.5 hot spot analysis was completed, as required by 40 CFR 93.116 and 93.123, based on U.S. EPA Guidance. The project comes from a conforming Regional Transportation Plan (RTP) and Transportation Improvement Program (TIP). Comment was requested regarding the project-level conformity analysis, which is included in the IS/EA. Comments on the IS/EA were due on February 5, 2014. For more information on the IS/EA, contact Valerie Shearer, Caltrans, at (510) 286-5594 valerie_shearer@dot.ca.gov.
