Connecting Communities

From transporting freight to connecting regional commuters, Contra Costa depends on our hardworking local highways. CCTA is committed to strategically investing in this critical infrastructure, making highways smarter, and increasing efficiency to meet growing demand.

Modernizing a Key Regional Link
A community celebration and ribbon cutting on July 20, 2016 marked the completion of the Highway 4 Widening Projects, a six year long collaborative endeavor by the Contra Costa Transportation Authority (CCTA), the California Department of Transportation (Caltrans), Bay Area Rapid Transit (BART), the Metropolitan Transportation Commission, the California Transportation Commission and the Federal Highway Administration.

Highway 4 was for years one of the worst commutes in the Bay Area. By expanding Highway 4 from four to eight lanes between Loveridge Road in Pittsburg, to just west of State Route 160 in Antioch, and from two to four lanes from Lone Tree Way to Balfour Road in Brentwood, that commute time has been cut. The projects also added missing connector ramps at the State Route 160/Highway 4 interchange and will add a BART extension from Pittsburg to Antioch. This will greatly improve transit accessibility for the region, help reduce traffic congestion and enhance the quality of life for the more than 250,000 residents of eastern Contra Costa County. The BART station at Hillcrest is expected to open in the winter of 2017/2018. 

CCTA has created a webpage to tell the story of Highway 4 projects through images videos that pay tribute to the many entities and individuals involved in ensuring the success of these vital projects. See the many stories of the Highway 4 projects at 4eastcounty.org/stories.
 
Innovating Our Way to Congestion Relief
CCTA is committed to ensuring cutting-edge technology will make commutes safer and more efficient. In 2016 we implemented the I-80 SMART Corridor, one of the most sophisticated Intelligent Transportation Systems in the state. It is a network of integrated electronic signs, ramp meters and other state-of-the-art elements between the Carquinez Bridge and the Bay Bridge on I-80 to enhance safety, improve travel time reliability, and reduce accidents and associated congestion.

CCTA is also utilizing a planning grant to study a similarly "smart" set of integrated technology infrastructure to provide drivers with real-time information and improve commute times along a newly modernized Highway 4.
 
Creating an Efficient Express Lane Network
CCTA is partnering with the Metropolitan Transportation Commission (MTC) on their first Express Lane project in the Bay Area on I-680 between San Ramon and Walnut Creek. The project will convert existing High Occupancy Vehicle Lanes (HOV) to Express Lanes for approximately 12 miles in each direction. A future project will add Express Lanes southbound from the Benicia Bridge to Dublin.

Express Lanes operate like HOV lanes for carpoolers and buses, but also allow single-occupant vehicles to enter by paying a fee if carpool and bus use is below capacity in the HOV lane.

When both of these projects are complete, it will provide a continuous southbound Express Lane on I-680 between the Martinez-Benicia Bridge and Dublin.
