State Route 4 Widening Bailey Road Interchange

This project reconstructs the State Route 4/ Bailey Road interchange to accommodate the expansion of State Route 4 to eight lanes and to allow for the construction of the new West Pittsburg/ Bay Point BART station. West of the interchange, State Route 4 is widened from four lanes to six lanes with sufficient width between the eastbound and westbound lanes to accommodate two future HOV lanes and the BART extension to east Contra Costa County. East of the Bailey Road interchange, State Route 4 conforms to the existing four lane facility.

This project also provides landscaping along the highway, at the Bailey Road interchange and the Delta De Anza Trail.
