New Lanes Open to Traffic on Highway 4

ANTIOCH - This morning, Caltrans and 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.

"The benefits this project brings to the East Bay are significant. It is boosting the local economy by providing jobs, and commuters will benefit with more transit options and less traffic congestion,” said Caltrans Director Malcolm Dougherty.
