Corps Awards Miter Gate Contract To G&G Steel

The St. Paul Engineer District recently awarded an $18 million contract to G&G Steel Inc., of Russellville, Ala., for the fabrication of new miter gates at Lock 3, near Welch, Minn., and Lock 4, near Alma, Wis., on the Mississippi River.

The original miter gates on the two locks are from the 1930s. Over time, the gates have been damaged and distressed, which has led to serviceability issues. The new gates will increase navigational longevity and operational readiness in support of navigation.

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.

The St. Paul Engineer District’s navigation program supports the waterborne transportation system on the Upper Mississippi River for the movement of commodities and for national security. The district maintains a 9-foot navigation channel and 13 locks and dams between Minneapolis to Guttenberg, Iowa.
