A community celebration and ribbon cutting this morning 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, an important artery spanning nearly all of Contra Costa County, was for years one of the worst commutes in the Bay Area. The Highway 4 Widening Projects include improvements that expand 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. 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. Read the full news release
