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.
The tow rail system is integral to the operation of Mississippi River Locks and Dams 2 through 10. At each lock, a tow rail system is attached to the top of the lock guidewall to help guide tows through the lock chamber. The tow rail systems of Locks and Dams 2 through 10 have been deteriorating over the past several years, requiring rehabilitation of these systems.
