LLOYD, Ky. (AP) -- The U.S. Army Corps of Engineers has begun work to replace an aging gate at the Greenup Locks and Dam on the Ohio River.

The Independent (http://bit.ly/N0EHuI ) reports an emergency gate and bulkhead have been put into place to hold back the water while crews with the U.S. Army Corps of Engineers' Huntington District and private contractors work to remove the concrete-encased steel along the walls of the chamber where the gates are anchored.

The entire miter gate on the upper end of the lock will be replaced over two months.

While the work is ongoing, the main chamber is closed and barges have to travel through an auxiliary chamber that is half the size.

Corps officials say river traffic should expect delays until the chamber reopens in September.
