LLOYD, Ky. (AP) -- The U.S. Army Corps of Engineers say work to replace a set of aging mite gates at the Greenup Locks and Dam on the Ohio River will begin in June.

The $12 million project will replace a set of hydraulic doors and will close down the 1,200-foot-long main lock chamber on the Ohio River between Greenup County, Ky., and Lawrence County, Ohio, for about 12 weeks.

Project manager Mike Keathley told The Independent (http://bit.ly/HtcNkN ) that all river traffic will have to pass through an auxiliary chamber, which will take more time. Keathley says crews are making preparations to ease congestion while the main lock is under construction.

The newspaper reports that the Greenup Locks and Dam is one of the country's 10 busiest inland navigation locks.
