The U.S. Army Corps of Engineers, St. Paul District, recently awarded an $18 million contract to G&G Steel, Inc., of Russellville, Alabama, for the fabrication of new miter gates at Lock and Dam 3, near Welch and Lock and Dam 4, near Alma, Wisconsin.
The original miter gates are from the 1930s.
Over time, the gates have been damaged and distressed, which led to serviceability issues.
The new gates will increase navigational longevity and operational readiness in support of the economically significant navigation infrastructure.
The Lock 4 miter gates are scheduled to be delivered in July 2028 for installation later that summer, and the Lock 3 miter gates are scheduled to be delivered in July 2029 for installation later that summer.
