Computer image of reconstruction of the building of the Gatun Locks
It took four years to build all of the Canal's locks, with the first concrete being laid at Gatun on 24 August 1909. The amount of concrete needed in Panama was of a huge volume - such quantities were not required for any other project until the building of the Hoover Dam, in Nevada, in the 1930s.
After more than 80 years of service, the concrete of the Panama Canal locks and spillways is still, in 2003, near perfect condition. It is a fine testament to the Canal's engineers and builders.
