Murray Lock and Dam
From FranaWiki
Murray Lock and Dam is located on the Arkansas River. The lock and dam is part of the McClellan-Kerr Arkansas River Navigation System, a series of navigable pools on the Arkansas River formed from seventeen locks, dams, and reservoirs extending from the Port of Catoosa near Tulsa, Oklahoma, to Montgomery Point near Dumas on the Mississippi River. The McClellan-Kerr system is operated by the U.S. Army Corps of Engineers in Little Rock and Tulsa.
The Big Dam Bridge is mounted atop Murray Lock and Dam by 38 separate columns. In some places the bridge is thirty feet above the dam and sixty-five feet above the level of the river.
