Hey, all you Vertical Lift Gate Design junkies -- do we have a treat for you!!! We just released our historical publication on the transitional design technology applied during the construction of the first vertical lift gates on the Ohio River Navigation System.  This study examines the engineering and political factors involved in the historical evolution of controlled crest gate technology on the Upper Ohio River, the conditions and events leading up to construction of the dam, and the degree of influence of the Montgomery gates on subsequent dams built on the river by the Corps. So grab your slide rule, a cup of joe, a digital copy of the MONTGOMERY LOCKS AND DAM, OHIO RIVER Direct Vertical Lift Gates – Design History, and chow down on magnificent chunk of engineering history!!!
