In 1945 after WWII, the National Council of Garden Clubs (Now National Garden Clubs, Inc.) began dedicating Blue Star Memorial Highways with markers to honor service members.  The custom has since grown to include Memorial Markers and Byways found in National Cemeteries, Parks, Gardens and veterans facilities. These standardized plaques are available for purchase, fabricated to order, for continuing commemoration. Following the National Garden Club’s designation process, Interstate 680 was dedicated in 1971 by their Bay Bridges District Council.
