(Switzerland County, Ind.) - New lock doors are on site and will be installed within the next year at the Markland Dam on the Ohio River.
The first new lock gate arrived
in Louisville last March.

Two 250-ton doors arrived by barge this week. The gate leaves were constructed in Oregon and had been stored in Louisville since March.
The replacement gates will be installed next summer by the U.S. Army Corp of Engineers once two more doors arrive this winter.
The dam’s current doors were repaired after being damaged. A solenoid valve failed in the 1,200-foot main lock in September 2009.
For several months after the lock was damaged, barge traffic was forced to use a smaller 600-foot auxiliary lock.
In 2008, the Markland Dam and Locks saw about 55.6 million tons of commodities pass through.
