The Highway 4 projects include improvements to the entire project corridor that will help revitalize eastern Contra Costa County. The projects expand Highway 4 from four to eight lanes between Loveridge Road and SR-160, and add a BART extension from Pittsburg to Antioch (eBART). The projects will also expand the highway from two to four lanes from Lone Tree Way to Sand Creek Road.
This will greatly improve transit accessibility for the region and 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, and include over $1.3 billion in State, Federal, Regional Bridge Toll, and Contra Costa Measures C & J sales tax funds.
Caltrans and CCTA appreciate your patience as we work to improve the highways. For the most current
