The Morganza Spillway

On Monday, Memorial Day, we took a drive to parts of Louisiana we hadn't visited before. We came across the Morganza Spillway. As we approached it, the swolleness of the spillway was obvious.

The Morganza Spillway is a floodway used in connection with the Old River Control Structure and the Atchafalaya River located in northeast Central Louisiana. The use of the spillway would be used in case of a flood from the Mississippi River. It would ultimately divert water from the river into the Morganza Spillway and into the Atchafalaya Basin. It was used in 1973 to relieve pressure from the Old River Control Structure. U.S. Highway 190 has a 4-mile bridge that travels over the spillway. The old 2-lane bridge is used by the United States Army Corps of Engineers. (Yep, that's from Wikipedia.)
