WARSAW, KY (FOX19) -

The U.S. Army Corps of Engineers Louisville Repair Station have set the second of two 260 ton gate leaves at the downstream end of the Ohio River Markland navigation locks.

"People don't go around lifting that kind of weight every day," said Keith Browning, Louisville Repair Station, who directs the Henry M. Shreve gatelifter vessel, lock repairs and crew at the Markland Locks at Warsaw, Ky.

Upstream gates are scheduled to be set at the end of September or beginning of October.

The gates were fabricated by Oregon Iron Works and floated through the Panama Canal, up the Mississippi and Ohio rivers to arrive in the region. The repair fleet still needs to install the two remaining upper gate leaves.

The installation of the new gates will complete the Markland Major Rehabilitation project by the Army Corps of Engineers which began in 2009.
