Calaveras Road CLOSED

Calaveras Road is closed to all types of thru traffic 7 days a week, 24 hours a day between Geary Road and Oakridge Road – near the Alameda/Santa Clara County line. 

This is due to storm damage along this stretch of road. Under normal conditions and the construction schedule, Calaveras Road would be open to thru traffic on weekends and holidays. However, this is no longer the case, and the road will remain closed every day to all traffic until further notice.
