Construction of Gatun Locks
Stories from the United States' relationship with the Panama Canal, in celebration of its centenary
The Gatun Locks were the last locks to be finished. Of all of the sets of locks, they were the most complex to build, since the Gatun Locks have to generate a total elevation of 25.9 meters using a three-step system. The set of locks on the Atlantic side is composed only of the Gatun Locks. The construction of these locks was the most delayed part of the Canal building since they are substantially longer than the other two. The Gatun Locks were completed on September 26, 1913, and the first trial closure of the Gatun Locks was made that day.
