The complete $462M project included the rail tracks, two stations, a park and ride facility, and maintenance building. The contract included modifications to ten miles of BART rail tracks beyond the Pittsburg/Bay Point station, a new transfer platform, and a building to house train control equipment.
The project accommodated a diesel train to run the median of State Route 4 from the existing Pittsburg/Bay Point BART station to an eBART terminus station in Antioch.
Additional work performed by Caltrans included widening of the State Route 4 median to accommodate the eBART tracks, and an access tunnel under State Route 4. The project was built in conjunction with the expansion of State Route 4 from four lanes to six and eight.
