Panama Canal, Panama
The idea of digging a passage across the Isthmus of Panama uniting the Atlantic and Pacific Oceans finally came to fruition when the Panama Canal was completed on August 15, 1914.
The French began this massive construction project and the United States finished the job. Total cost was $375 million, and nearly 25,000 people died during the effort.
The canal was managed by the United States until December 31, 1999, at which time (by treaty) is was taken over by the Panamanian government.

The Panama Canal is one of the greatest engineering works ever to be undertaken and each large ship that transits the Panama Canal has its own tug boat, in the event its movement needs to be controlled and expensive damage be prevented. Some of the larger vessels need two, and those tugs are relatively small, but very powerful.
This is one of the Panama Canal visitor centers, and on any given day hundreds of tourists and locals come here to watch the massive ships move through the canal. The center is easily reached from Panama City, and tours are reasonably priced.
Note the container ship leaving the lock complex to the open water ahead. There are three sets of locks in the canal, and all are used 24/7 365. When a ship traveling from the Atlantic side reaches the Gatun Locks, a series of three locks raise that ship about 85 ft. to Gatun Lake. Then it's a 40 mile trip to the locks at Pedro Miguel, locks that lower the ship 30 feet. At the Miraflores locks the ship is lowered an additional 52 feet to Pacific Ocean sea level. The reverse is true for ships traveling in the opposite direction.
