The extended closures will facilitate demolition, concrete construction, and installation and commissioning of the new miter gates. For each closure cycle, the large lock will close for no more than 30 days and will open for 15 days for vessel traffic.
The small lock will remain open during these periods and can pass vessels up to 28 feet wide and 123 feet long.
Most machinery and equipment, including the large lock center gate, are original to the Locks. The improvements to this 105-year-old navigation infrastructure will help the Army Corps supply reliable and dependable navigation over the years to come.
