$3.2 million contract awarded for miter gate anchorages at Lock 2

Published Oct. 22, 2019

ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, recently awarded a $3.2 million contract to Kaiyuh Services, LLC, out of Fort McCoy, Wisconsin, to install new miter gate anchorages at Lock and Dam 2, near Hastings, Minnesota.

The work will involve concrete repairs and the installation of newly fabricated anchorages. Each lock has a set of upstream and downstream miter gates which act as doors to the lock chamber. The anchorages act as door hinges for the miter gates.

“This is important maintenance to keep operating the lock efficiently for the navigation industry. If the anchorages fail, the gates would fall of their hinges, ultimately stalling navigation of the Upper Mississippi River,” said Nick Castellane, project manager.

This work is in preparation for the delivery and installation of new miter gates in the summer of 2021. These new miter gates will be replacing the original gates installed in the 1940s. Work is anticipated to begin in late November 2020 and should be completed by early March 2021.

The St. Paul District navigation program provides a safe, reliable, cost-effective and environmentally sustainable waterborne transportation system on the Upper Mississippi River for the movement of commercial goods and for national security needs. To do this, the district maintains a 9-foot navigation channel and 13 locks and dams from Minneapolis to Guttenberg, Iowa. Keeping this system open is vital to the nation's economy.
