Concrete Barrier was added at Fish Ranch Road

According to caldecott-tunnel.org, Caltrans crews added sections of concrete barrier to the southern edge of the pavement on Fish Ranch Road, adjacent to the area where the new retaining wall is being built. The barrier will prevent errant vehicles from traveling off the pavement over the steep hillside.
