LOUISVILLE, KY. – The navigation pass at Lock and Dam 52 (Ohio River Mile 938.9), Brookport, Illinois, is now closed to river traffic to facilitate diving operations for wicket repairs on the dam.
The dive deflector box is being installed and diving operations will commence to repair/replace wickets. Repairs to the navigable pass wickets will add reliability to the dam and allow for a potentially shorter dam raising. Keeping Lock and Dam 52 operational is required for construction and training benefits at Olmsted Locks and Dam.
The U.S. Army Corps of Engineers (USACE) is mitigating the closure by preparing the 1200’ foot lock chamber for navigation, which is planned to be operational for locking river traffic by Wednesday, July 11. The navigable pass is also expected to reopen to river traffic on Wednesday during nighttime hours when daily diving operations have concluded.
USACE will closely coordinate daily updates and traffic movement with the Coast Guard and river industry.
