"Panama Canal Locks
The Panama Canal Locks, which lift ships up 25.9 m (85 ft) to the main elevation of the Panama Canal, were one of the greatest engineering works ever to be undertaken at the time, eclipsed only by other parts of the canal project. No other concrete construction of comparable size was undertaken until the Hoover Dam in the 1930s. The total length of the lock structures, including the approach walls, is over 3 kilometres (nearly two miles).
The locks, which have a total of six steps, limit the maximum size of ships which can transit the canal, known as Panamax. Each of these steps has two lock chambers, doubling the amount of traffic that can be handled; together they raise ships from sea level to a height of 25.9 m (85 ft)."
Yeah baby now that what I call a lock!
