About the Project

As many as 270,000 vehicles per day use the I-80 corridor, one of the busiest in the Bay Area. The I-80 SMART Corridor Project, representing one of the most sophisticated Intelligent Transportation Systems in the state, is implementing a network of integrated electronic signs, ramp meters and other state-of-the-art elements between the Carquinez Bridge and the Bay Bridge to enhance motorist safety, improve travel time reliability and reduce accidents and associated congestion.

Real-time traffic information, such as variable speed signs and blocked lane signs, will allow drivers to make informed decisions in the event of an incident. Additional improvements include real-time ramp metering on 44 on-ramps to reduce merging conflicts and manage traffic volumes on I-80. Once activated in mid-2016, these ramp meters and real-time message signs along the corridor will contribute to optimized roadway operations and improved safety, and will be integrated with, and managed from, the Traffic Management Center at the Caltrans Bay Area headquarters in Oakland.

Have you seen the big electronic signs on westbound Interstate 80 (Eastshore Freeway) between Richmond and the Bay Bridge? These are part of the project, which broke ground in 2011 and is anticipated to be operational in mid-2016. To learn more about the new signs for freeway drivers that will provide real-time recommended speed limit, traffic accident and other information, as well as the new smart ramp-meters along the corridor, download the project fact sheet (Descripción del Proyecto, 項目簡介) or view a project video below.

FUNDING OVERVIEW

The I-80 SMART Corridor Project is funded by approximately $79 million from the Corridor Mobility Improvement Account (CMIA) created by State Proposition 1B, approved by Californians in 2006 for transportation needs, the Contra Costa Transportation Authority’s Measure J half-cent sales tax and the Alameda County Transportation Commission’s Measure B half-cent sales tax.
