KP-2063-R2 - Klamath Project. Lost River Diversion Channel Control Structure and Railroad Bridge. Close-up of pier showing 3/4" dowels and prepared concrete face. While driving piling, the concrete projection in this pier cracked so it had to be removed. This accounts for the broadened face and a greater amount of dowels; August 31, 1950; Photo by Andrew M. Bergloff
