Bonus topic for the week of 07/06/25 - 07/12/25:
There are many engineering marvels that have been produced in history, but maybe none as incredible as the creation of the Panama Canal. The idea for a direct trade route between the Pacific and Atlantic Oceans was conceived as far back as 1513 by Spanish conquistador Vasco de Balboa, but that’s as far as he went with it. The narrow isthmus was instead used to transport plunder by land to the Caribbean side for delivery to Spain. The concept gained traction over the centuries, including an alternate route across Nicaragua, but very little was done to make it a reality until the late 19th century. Enter the French in 1881 led by engineer Ferdinand de Lesseps, who was responsible for the construction of the Suez Canal in 1869. Similar to the Suez, de Lesseps planned a sea level canal across the 50-mile isthmus, a massive endeavor in and of itself, made worse by environmental conditions, landslides and disease. It is estimated that 200 people a month were dying of diseases, but at the time, it wasn’t known that mosquitos were carriers for things like malaria and yellow fever. It is also estimated that over 22,000 workers died over the construction period and eventually the French effort was abandoned. The U.S. took over in 1904 after helping Panama secede from Colombia. By this time the mosquito problem had been identified, living conditions had been improved and the plan for a sea level canal was scrapped. Instead, engineers relied on a series of locks that would raise and lower ships 85 feet to a large man-made reservoir, eliminating the need to remove as much earth as the French plan. Ten years later, hundreds of steam shovels, millions of sticks of dynamite and nearly 5 million cubic yards of concrete and the Panama Canal was complete, still at the loss of about 5,600 lives. With the opening of the canal, it shortened the shipping route from around the tip of South America, a distance of around 8,000 nautical miles. The convenience of not having to travel that far though comes at a price. Nowadays, the fee for traveling through the canal averages about $150,000, but can run over $1,000,000. About 14,000 ships pass through the canal yearly which takes about ten hours to cross. Check out the 15-minute YouTube video, The Engineering Marvel Called Panama Canal by Sabin Civil Engineering. It’s a comprehensive description of the history and the construction of the canal, a very informative watch.
This week’s bonus question:
The Panama Canal officially opened on August 15th, 1914 with the crossing of the cargo ship, SS Ancon, but this sister ship actually made the first crossing on August 3rd (not the floating crane)?
