It would have taken around 21 days if the Panama Canal were operational and saved some 8, miles 12, kilometers of travel.
For years, the U. But engineering concerns — not to mention worries about active volcanoes in the area — prompted President Teddy Roosevelt to continue with the failed French site in Panama instead.
As the Americans took control, the building of the Panama Canal became an audacious example of American ingenuity and know-how. By the end, the U. The project came in some percent over budget. Besides the deadly diseases that plagued the early days of the construction, the difficult weather tropical rains and intense heat and the costs, engineers debated the very nature of the Panama Canal early on.
They finally abandoned ideas about a sea-level canal like the Suez , with Stevens instead insisting upon a series of locks that would raise or lower ships as needed. But that design necessitated construction of another big project. Gatun Dam, at one time the largest dam in the world, had to be built across the sometimes-raging Chagres River to ensure the proper flow of water between the Pacific Ocean and the Atlantic.
That formed Gatun Lake, a major component of the canal's operation more on that below. And then there was the sheer scope of the project: Between the French and American builders, some 7. Most of the muck was placed onto railcars, shipped to the coasts and dumped into huge piles in the ocean. It now forms breakwaters and the foundation for towns and a military base.
Much was dumped into the adjacent jungle, too. And it didn't afterward for a long time. Also a continuing problem: landslides. Yet despite the constant challenges, the Panama Canal opened in August , with the SS Ancon becoming the first ship to officially make the trip through.
All over this year period, all diverted down to Panama. In its first five years, decreased traffic because of World War I and a series of landslides which closed the passage for almost all of and would continue for years , the canal was barely used. That would soon change. At the other end of the canal, a similar process will be performed in order to lower the vessel to sea level.
For a ship entering the canal from the Atlantic end, travelling in a southeast direction, the first entry will be into the first sea level lock chamber located at the Gatun Locks. After the vessels entered the chamber, the watertight lock doors are closed by the lock-master and the valve is opened to allow the flow of water from the adjacent second lock chamber, 28 feet above sea level. However, no pumps are used here; the entire operation of equalizing the water levels between the locking chambers on the Panama Canal depends on the principles of gravity to move the water and on the fact that water seeks its own level.
When the water levels of two adjacent chambers are equal, the water stops flowing from the water culverts. Once the water levels between the first and second chamber are the same, the valve gets closed by the lock-master and the watertight lock doors between the first lock chamber and the second lock chamber are opened subsequently. This process allows the ship to proceed to the second lock chamber. The first operation is repeated then between the second lock chamber and the third lock chamber, which raises the ship to the level of Gatun Lake.
After the closure of the final valve and opening of the watertight lock door, the ship is raised 85 feet above sea level and is able to continue its journey to the Pacific. The same process inversely is followed in order to send the ship back to sea level. At the Pedro Miguel Locks on the Pacific end of the canal, when the ship enters the first chamber, the watertight doors are closed and the valve gets opened on that lock chamber, allowing water to drain from the first lock chamber into the relatively lower second lock chamber.
After the water level between the two chambers is at the same level, the watertight doors are opened allowing the ship to continue to transmit down the Gaillard Cut to the Miraflores Locks, where the operation of lowering the ship to sea level is completed.

The views constitute only the opinions and do not constitute any guidelines or recommendation on any course of action to be followed by the reader. Each set of locks consists of two lanes. The lanes are not for locking ships in opposite direction at the same time as people might think which occurs invariably as a coincidence but rather they were built that way so one could be completely closed for maintenance work while the other remains available for shipping.
This way the canal does not have to cease servicing the industry. Ships move through these locks with the assistance of powerful locomotives known also as mules as an analogy with those strong and stoic beasts while using their own engines.
Tugboats are also used in assisting ships, depending on their size, to arrive and enter the locks. Even after a century of constant use and having transited more than a million ships safely, the great steel gates of the Miraflores locks still swing open with the precision comparable to that of a Swiss watch.
Each of these ton locks is operated with the help of a pair of horsepower motors. These new set of locks, capable of handling vessels with a length of feet Unlike the old Panamax locks, these new ones called Neo Panamax locks were designed with recycling pools in order to minimize water consumption. Instead of locomotives, ships are assisted by tugboats tied up at each end. Apart from their huge difference in size the new locks, Agua Clara on the Atlantic and Cocoli on the Pacific side were each built as three steps locks.
There is no intermediate lake like in the case of Miraflores and Pedro Miguel. Ships are raised to Gatun lake level, or lower to sea level, once they pass through these new locks. All the water used for locking ships up or down goes out to sea by gravity.
This is why rainfall is very important to keep the canal operational. An average of 52 millions gallons of water is necessary for every ship that uses the old locks. In the case of the Neo Panamax locks, the recycling pools contribute to saving about 33 million gallons of water, while letting 22 million gallons drain out to sea.
Each vessel that transits is under the control of a Panama Canal Pilot. The complexity of the operation makes it a necessity. Depending on the size, vessels are assigned one or more pilots. It will stop in Balboa before proceeding to Manzanillo and probably some ports on the U. West Coast. If these new locks had not been built, ships this size would have to use Suez or just trade in a different route. To understand the importance of the Panama Canal we only have to think of the consequences for the shipping industry if, all of a sudden, it would not be available.
About routes, connecting ports from countries, depend on the waterway on a regular basis. An average of 14, transits is made every year through the Panama Canal. Ships of all types, carrying all kind of cargoes safely navigate the waters of the canal. Containers are at the top of the Panama Canal list users, closely followed by tankers and bulkers. With the new locks, gas tankers have found a shorter route to their destinations.
By using the canal not only does shipping takes a break in fuel expenses, but the environment also takes a break. As I write these last few lines, COVID is wreaking havoc in almost every facet of human activity all over the globe.
Workers at the Panama Canal, like everywhere else, are not immune to this virus. The Panama Canal is an engineering marvel. About 14, ships use it every year. The canal is about 48 miles long. It functions as a waterway between North and South America. The canal connects the Atlantic and Pacific Oceans. Before the canal, ships had to sail 13, miles around the tip of South America An artificial lake across Panama connects the oceans.
The Gatun Lake is 85 feet above sea level.
