In the ensuing centuries, various nations attempted to pick up the ball but no serious attempt was made until the s. In the French, led by Ferdinand de Lesseps , broke ground in their attempt to build a crossing. Plagued with poor planning, engineering issues, and tropical diseases, thousands of laborers met their untimely demise. De Lesseps's plan was to complete the project at sea level, eliminating the need for locks but the geography and geology had other ideas. Although the Panama Canal needed to be only 40 percent as long as the Suez Canal, it was much more of an engineering challenge, due to the combination of tropical rain forests, debilitating climate, the need for canal locks, and the lack of any ancient route to follow.
De Lesseps had visited the site only a few times, and only during the dry season which lasts just four months of the year. As a result, his men were totally unprepared for the torrents of the rainy season. On top of this, the dense jungle contained venomous snakes, insects, and spiders, along with yellow fever, malaria, and other tropical diseases. Thousands of workers died, and by , the death rate was over per month.
Frustrated by this, the French team recruited Gustave Eiffel , of tower fame, to design and create the lock system needed for the canal. The complexity of the project ended with the De Lesseps company filing for bankruptcy in , having sunk million USD into the project. The venture's failure was a scandalous event back home in France, with De Lesseps, Eiffel, and other executives indicted for misappropriation of funds.
De Lesseps and his son were convicted and sentenced to five years in jail, although this was later overturned. De Lesseps died in That same year, a new French company was formed to take over the assets of the bankrupt business and continue the canal; however, this second firm soon abandoned the endeavor as well. The United States had shown great interest in creating a trans-American canal for economic and military reasons, and had originally considered placing one in Nicaragua.
They were persuaded otherwise by one Phillippe-Jean Bunau-Varilla a French engineer involved in the earlier, failed French attempts. In the late s, Bunau-Varilla began lobbying American lawmakers to buy the French canal assets in Panama. He eventually convinced a number of them that Nicaragua had dangerous volcanoes, making Panama the safer choice. Congress authorized the purchase of the former French assets in , but there was one small problem.
Panama was at that time part of Colombia, which refused to ratify the agreement. Monsieur Bunau-Varilla and the U. With U. Soon after, the Hay-Bunau-Varilla Treaty was signed, giving America the right to a zone of more the square miles 1, sq km in which to build the canal. Under the treaty, the zone was to be an American protectorate for perpetuity. Surprisingly, the Nicaraguan option is still on the table today, years on, with a Chinese company announcing that it had struck a 40 billion USD deal to begin construction of a canal there.
It is estimated that the construction of the canal cost the lives of more than 25, workers. These unfortunate workers had to contend with challenging terrain, hot, humid weather, heavy rainfall, and numerous deadly tropical diseases. The French effort cost the lives of around 20, workers, with the American project between and costing the lives of somewhere in the region of 5, workers. Most of the deaths during the French attempt resulted from yellow fever and malaria.
The American attempt fared better, as medical knowledge had improved significantly. There was a better understanding of sanitation, in particular, including the need to drain mosquito breeding grounds, which significantly reduced the spread of the disease during the project. Every year, between 13 and 14 thousand ships traverse the canal.
On average, it takes between 8 and 10 hours to pass through. A toll must be paid for each transit, which is based on the ship size and cargo volume. For large ships, this can be thousand USD. By the time Goethals took over, the construction infrastructure had been created or overhauled and expanded from the French effort and he was soon able to begin construction in earnest.
Goethals divided the project into three divisions: Atlantic, Central and Pacific. The Pacific Division under Sydney B. Williamson, the only civilian division head was responsible for the Pacific entrance to the canal, including a 4. It had arguably the project's greatest challenge: excavating the Culebra Cut known as the Gaillard Cut from to , which involved cutting 8 miles 13 km through the continental divide down to 12 meters 39 feet above sea level.
One of the greatest barriers to a canal was the continental divide , which originally rose to metres The effort to cut through this barrier of rock was one of the greatest challenges faced by the project. Gaillard was placed in charge of the canal's Central Division, which stretched from the Pedro Miguel locks to the Gatun Dam , and dedicated himself to getting the Culebra Cut as it was then known excavated. The scale of the work was massive. Six thousand men worked in the cut, drilling holes in which a total of 27, t 60,, lb of dynamite were placed to break up the rock which was then removed by as many as trains per day.
Landslides were frequent, due to the oxidation and weakening of the rock's underlying iron strata. Although the scale of the job and the frequent, unpredictable slides generated chaos, Gaillard provided quiet, clear-sighted leadership. On May 20, , Bucyrus steam shovels made a passage through the Culebra Cut at the level of the canal bottom.
The French effort had reduced the summit to 59 metres About 23,, m 3 30,, cu yd of this material was in addition to the planned excavation, due to landslides. Dry excavation ended on September 10, ; a January slide had added 1,, m 3 2,, cu yd of earth, but it was decided that this loose material would be removed by dredging when the cut was flooded. Two artificial lakes are key parts of the canal: Gatun and Miraflores Lakes. Four dams were constructed to create them.
The Miraflores dams are an metre 2, ft earth dam connecting the Miraflores Locks in the west and a metre ft concrete spillway dam east of the locks. The concrete dam has eight floodgates , similar to those on the Gatun spillway. The earthen, metre 1, ft Pedro Miguel dam extends from a hill in the west to the lock. Its face is protected by rock riprap at the water level. The largest and most challenging of the dams is the Gatun Dam.
This earthen dam , metres 2, ft thick at the base and 2, metres 7, ft long along the top, was the largest of its kind in the world when the canal opened. The original lock canal plan called for a two-step set of locks at Sosa Hill and a long Sosa Lake extending to Pedro Miguel.
The resulting small lake Miraflores became a fresh water supply for Panama City. Building the locks began with the first concrete laid at Gatun on August 24, The Gatun locks are built into a cutting into a hill bordering the lake, requiring the excavation of 3,, m 3 4,, cu yd of material mostly rock. The locks were made of 1,, m 3 2,, cu yd of concrete, with an extensive system of electric railways and aerial lifts transporting concrete to the lock-construction sites. The Pacific-side locks were finished first: the single flight at Pedro Miguel in , and Miraflores in May The seagoing tugboat Gatun , an Atlantic-entrance tug used to haul barges, traversed the Gatun locks on September 26, The trip was successful, although the valves were controlled manually; the central control board was not yet ready.
On October 10, , the dike at Gamboa which had kept the Culebra Cut isolated from Gatun Lake was demolished; the detonation was made telegraphically by President Woodrow Wilson in Washington. On January 7, , the Alexandre La Valley ,  an old French crane boat, became the first ship to make a complete transit of the Panama Canal under its own steam after working its way across during the final stages of construction.
As construction wound down, the canal team began to disperse. Thousands of workers were laid off, and entire towns were disassembled or demolished. Chief sanitary officer William C. Gorgas , who left to fight pneumonia in the South African gold mines, became surgeon general of the Army.
Although a large celebration was planned for the canal's opening, the outbreak of World War I forced the cancellation of the main festivities and it became a modest local affair. Constantine the canal's first pilot , made the first official transit on August 15, With no international dignitaries in attendance, Goethals followed the Ancon 's progress by railroad.
The canal was a technological marvel and an important strategic and economic asset to the US. It changed world shipping patterns, removing the need for ships to navigate the Drake Passage and Cape Horn. The canal saves a total of about 7, miles 12, km on a sea trip from New York to San Francisco. Its anticipated military significance of the canal was proven during World War II , when the canal helped restore the devastated United States Pacific Fleet.
A total of over 75, people worked on the project; at the peak of construction, there were 40, workers. According to hospital records, 5, workers died from disease and accidents during the American construction era. A total of ,, m 3 ,, cu yd of material was excavated in the American effort, including the approach channels at the canal ends. Adding the work by the French, the total excavation was about ,, m 3 ,, cu yd over 25 times the volume excavated in the Channel Tunnel project.
Of the three presidents whose terms spanned the construction period, Theodore Roosevelt is most associated with the canal and Woodrow Wilson presided over its opening. However, William Howard Taft may have given the canal its greatest impetus for the longest time.
Taft visited Panama five times as Roosevelt's secretary of war and twice as president. He hired John Stevens and later recommended Goethals as Stevens' replacement. Taft became president in , when the canal was half finished, and was in office for most of the remainder of the work.
The following words by Roosevelt are displayed in the rotunda of the canal's administration building in Balboa : [ citation needed ]. It is not the critic who counts, not the man who points out how the strong man stumbled, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena; whose face is marred by dust and sweat and blood; who strives valiantly, who errs and comes short again and again; who knows the great enthusiasms, the great devotions, and spends himself in a worthy cause; who, at the best, knows in the end the triumph of high achievement; and who, at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who know neither victory nor defeat.
David du Bose Gaillard died of a brain tumor in Baltimore on December 5, , at age Promoted to colonel only a month earlier, Gaillard never saw the opening of the canal whose creation he directed. The Culebra Cut as it was originally known was renamed the Gaillard Cut on April 27, , in his honor. A plaque commemorating Gaillard's work stood over the cut for many years; in it was moved to the administration building, near a memorial to Goethals.
The largest US battleships already had problems with the canal locks, and there were concerns about the locks being incapacitated by bombing. These concerns led Congress to pass a resolution on May 1, , authorizing a study of improving the canal's defenses against attack and expanding its capacity to handle large vessels. A special engineering section was created on July 3, , to carry out the study. The section reported to Congress on February 24, , recommending work to protect the existing locks and the construction of a new set of locks capable of carrying larger vessels than the existing locks could accommodate.
On August 11, Congress authorized the work. The new locks would add a traffic lane to the canal, with each chamber 1, ft The first excavations for the new approach channels at Miraflores began on July 1, , following the passage by Congress of an appropriations bill on June 24, Following a referendum , work began in and the expanded canal began commercial operations on June 26, After a two-year delay, the new locks allow the transit of Panamax ships which have a greater cargo capacity than the original locks can handle.
The first ship to cross the canal through the third set of locks was a Panamax container ship , the Chinese-owned Cosco Shipping Panama. After construction, the canal and the Canal Zone surrounding it were administered by the United States. The treaty became effective on October 1, , providing for a year period in which Panama would have increasing responsibility for canal operations before complete US withdrawal on December 31, Although concerns existed in the US and the shipping industry about the canal after the transfer, Panama has exercised good stewardship.
The number of accidents has decreased from an average of 28 per year in the late s to 12 in Transit time through the canal averages about 30 hours, about the same as during the late s. On October 22, , Panamanian citizens approved a referendum to expand the canal. Former US Ambassador to Panama Linda Watt, who served from to , said that the canal operation in Panamanian hands has been "outstanding". From Wikipedia, the free encyclopedia.
