The video shows the lock gate installation and the gudgeon pin, a component located at the top of the structure, being set. The Army Corps of Engineers Louisville District Markland lock gate leaf weighs more than 260 tons. The Louisville Repair Station fleet performs the extraordinary work with the Henry M. Shreve gatelifter, a specialized tow and barge. The project is located on the Ohio River at Warsaw, Ky. The new gates signal the completion of the Markland Major Rehab which began in 2009.
