CONCORD, CA (June 2, 2021) – Contra Costa County Public Works starts construction of the Marsh Drive Bridge Replacement Project starting on Monday, June 7, 2021 through January 2023, barring unforeseen circumstances.
Work will occur between 7:00 am-4:00 pm, Monday-Friday, weather permitting. Work will take place on Marsh Drive, approximately 0.2 miles west of Solano Avenue. The area takes place in both unincorporated Contra Costa County and the City of Concord.
There will be restrictions to minimize impacts during commute hours. Because of this, the speed limit through the work area will be 25 mph during construction. Drivers should expect delays.
The project will include reconstruction of approximately 1,000 feet of Marsh Drive near the bridge. They will also install a retaining wall and make channel improvements. Work includes updating utilities including water, electric power, and communication facilities. Work includes replacing the existing bridge with a new concrete bridge in a slightly shifted alignment to the north in stages built to current standards.
Funding for this project is provided by Federal Highway Bridge Program Funds, Local Road Funds, Contra Costa County Flood Control District Zone 3B Funds, Pacific Gas & Electric Funds, Contra Costa Water District Funds, and East Bay Regional Park District Funds.
