Construction crews on Monday began the demolition of the westbound loop offramp from state Highway 4 to Bailey Road in Bay Point, part of the Bailey Road/Highway 4 Interchange Pedestrian and Bicycle Improvement Project, according to the Contra Costa County Public Works Department.

To prepare for the demolition, the offramp was permanently closed Saturday and traffic permanently redirected to the Highway 4 westbound diagonal offramp, which has been widened and now can accommodate both northbound and southbound traffic onto Bailey Road.

The project is expected to be completed sometime in October.

More information about the project is available on the county’s website.
