G&G Steel made sure it was in attendance at a ribbon-cutting for the Olmsted Locks and Dam. After all, the fabrication company built five of the structure’s Tainter gates, which also happen to be the largest the company has ever built. Measuring 41 feet high and 110 feet deep, the gates weight approximately 350 tons apiece.
The Olmsted Locks and Dam are located about 17 miles upstream from the confluence of the Ohio and Mississippi rivers at Olmsted, Ill. The Tainter gate is a type of radial-arm floodgate used in dams and canal locks to control water flow.
