Mississippi River Locks and Dams 2–10: Miter Gate Replacements

Locks and Dams 2 through 10 have used the same miter gates since their construction in the 1930s. Over time, the gates have been damaged and distressed, leading to serviceability and safety issues. This project will replace the gates and upgrade the anchorage systems, increasing navigational longevity and operational readiness while decreasing repair costs and downtime due to maintenance or failure.

Maintenance of dam spillway gates are required to avoid degradation and eventual replacement. Cost analyses show it is economically favorable to maintain these gates rather than replace them. There are also reliability and safety concerns with allowing the gates to degrade to the point that they must be replaced.
