Antioch, CA: This morning, Caltrans and the Contra Costa Transportation Authority (CCTA) opened two additional westbound highway lanes from Contra Loma Blvd/L Street in Antioch to Loveridge Road in Pittsburg, marking a major project milestone for Highway 4 widening work between Pittsburg and Antioch.

The new westbound lanes, combined with the eastbound lanes that opened in November, provide more than 15 lane miles of additional capacity along a three-mile section of Highway 4.
CCTA is committed to bringing congestion relief to motorists and transit users as soon as possible by opening expanded highway segments along Highway 4 as they are completed. Today’s opening represents the completion of the first two segments of construction, with three more segments in progress from Contra Loma Boulevard to Hillcrest Avenue. These remaining segments are expected to be complete in late 2015. At that time, 33 miles of Highway 4 from Antioch to Hercules will have been widened from the original two lanes, a process that began in 1988 with funding from Contra Costa’s half-cent transportation sales tax measure.

“CCTA is pleased we can provide increased capacity on these segments of Highway 4 just in time for the holidays, making it easier for residents of East County to spend more time with family and friends and less time on the highway,” said Randy Iwasaki, Executive Director, CCTA.
“These new lanes add another chapter to the ongoing success story along Highway 4,” said Caltrans District 4 Director Bijan Sartipi. “Congestion is decreasing, and drivers are less frustrated by delays. In addition, the new HOV lanes offer commuters a viable option to solo driving.”

The Highway 4 corridor improvement projects will bring congestion relief and expanded public transportation access to the residents of eastern Contra Costa County through the widening of the highway from two to four lanes in each direction, including an HOV lane accessible to carpools and transit vehicles, and median widening to accommodate BART expansion (eBART).

About Highway 4 Corridor Improvements & eBART:
The Highway 4 projects include improvements that will help revitalize eastern Contra Costa County. The projects expand Highway 4 from four to eight lanes between Loveridge Road in Pittsburg to just west of State Route 160 in Antioch, from two to four lanes from Lone Tree Way to Sand Creek Road in Brentwood, add missing connector ramps at the Highway 4/State Route 160 interchange, and add a BART extension from Pittsburg to Antioch (eBART). 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 projects have been carefully staged to keep 130,000 vehicles per day moving as major construction and demolition work continue. These projects, plus previously constructed projects in the region, bring the total investment in East County to $1.3 billion, including State, Federal, Contra Costa Transportation Authority Measures C and J, regional bridge tolls, and other funds.
