There is significant progress to report along the Highway 4 corridor, including the BART extension!
On July 10, the pedestrian bridge was lifted into position over Highway 4 at the site of the future Antioch Bay Area Rapid Transit (BART) Station. This was a major step in moving the project toward completion. Watch the video of the lift taking place below. Work continues along this corridor as construction crews are laying ballasts and tracks for the new BART line.
Contra Costa Transportation Authority (CCTA) is proud to fund the new Pittsburg Center Station, along with our partners BART, the Metropolitan Transportation Commission (MTC), and the City of Pittsburg. The station’s groundbreaking is slated for later this year.
The Highway 4 project also includes improvements that will increase capacity for commuting to and from eastern Contra Costa County. The project expands Highway 4 from four to eight lanes between Loveridge Road in Pittsburg to just west of State Route 160 in Antioch. It also widens the highway from two to four lanes from Lone Tree Way to Sand Creek Road in Brentwood with space for possible future BART extensions.
The Loveridge and Somersville segments of the project have been completed. The Sand Creek Interchange, which was completed in October 2014, removed a signalized intersection on the highway that had the highest accident rate in Brentwood and replaced it with a grade-separated intersection where Sand Creek Road meets Highway 4. The remaining project segments at Lone Tree Way, Contra Loma Boulevard, and Hillcrest Avenue are expected to be completed in the spring of 2016.
