Hillcrest Avenue

Pouring concrete for highway shoulderThe Hillcrest Avenue segment is the fifth and final construction segment along the main project corridor, ending in the city of Antioch. The project will widen the highway from four to eight lanes, including three mixed flow lanes and one High Occupancy Vehicle (HOV) lane. The project includes a median wide enough to accommodate mass transit (eBART), as well as provisions for a new eBART station just east of Hillcrest Avenue.

Watch a video walkthrough of the future Antioch eBART station.
