The sun sets as work continues at Cannelton Locks and Dam on the Ohio River in Cannelton, Indiana. The 1200-foot primary chamber at Cannelton Locks and Dam is temporary closed to allow the Regional Rivers Repair Fleet’s heavy capacity fleet to replace the miter gates and related equipment on each end of the chamber to increase reliability and efficiency on the inland waterways system.
