The intersection of Country Club Drive and Rohnert Park Expressway will be closed today and tomorrow as crews install a new water line. The work has been long planned and is not due to damage from Sunday’s earthquake in Napa County.

At the north side of the Country Club Drive and Rohnert Park Expressway intersection, the northbound and southbound lanes will be closed to through traffic on Tuesday and Wednesday. Northbound and southbound vehicles will be primarily detoured via San Simeon. Detour signs will be posted and in operation from 8:00 a.m. until 4:00 p.m. each day.

Through traffic on westbound Rohnert Park Expressway will be reduced to the left lane throughout the intersection. Eastbound through traffic on Rohnert Park Expressway will not be affected.

Traffic delays are anticipated. Drivers should allow for additional time to travel through the intersection or make alternate plans to avoid the area.
