Lock to have reduced hours for maintenance

Critical maintenance work and the unwatering of the lock chamber at the Jerry F. Costello Lock and Dam (Kaskaskia) will result in the following reduced hours of operation and lock closures.

June 25 – June 29: Closed 6 a.m.-6 p.m. to all traffic, the lock will be available 6 p.m.-6 a.m.

July 2 – July 4: Closed 6 a.m.-6 p.m. to all traffic, the lock will be available 6 p.m.-6 a.m.

July 9 – July 20: Closed 24 hours to all traffic.

July 30 – Aug. 19: Closed 24 hours to all traffic.

The unwatering of the lock chamber in August will be the first in the project’s history, allowing inspections of the structure and critical repairs to be completed. Other work includes mechanical dredging, diving operations for inspections of the lock bulkhead slots and PLC upgrades to the lock control system.
