Eighty-two kilometres of locks still beat Cape Horn
The Panama Canal cuts 82 kilometres across the Isthmus, linking Caribbean and Pacific trade without rounding South America’s tip. Locks raise ships into Gatun Lake, an artificial freshwater reservoir 26 metres above sea level. Opened on 15 August 1914, it remains one of history’s hardest engineering projects.
Balboa crossed the isthmus in 1513 and noted that a waterway might be possible. Scotland’s Darien scheme of 1698 to 1700 collapsed under brutal conditions, and in 1811 Humboldt sketched five candidate routes across Central America. The 1846 Mallarino–Bidlack Treaty gave the United States transit rights in New Granada, along with a right to intervene militarily, and the California gold strike of 1848 suddenly made a quick crossing valuable.
William Henry Aspinwall seized that demand with steamers from New York to Panama and onward to California, linked by an overland portage, and Cornelius Vanderbilt soon competed. Between 1850 and 1855 Aspinwall’s syndicate laid a railway from Colón to Panama City. It cost about eight million dollars, six times the estimate, and killed somewhere between 6,000 and 12,000 builders. In 1870 President Grant’s Interoceanic Canal Commission surveyed Humboldt’s routes and settled on Nicaragua as the preferred American option.
France moved first anyway. Ferdinand de Lesseps, celebrated for building the Suez Canal between 1859 and 1869, joined engineer Philippe Bunau-Varilla after the Türr Syndicate approached him in 1875; Lucien Bonaparte-Wyse and Armand Reclus scouted routes from 1876 to 1878. Work began in 1881 and was abandoned by 1889 amid engineering failures, investor panic and appalling death rates among labourers.
The United States took over in 1904, finished the canal for its 15 August 1914 opening, and administered the surrounding Canal Zone for decades. The finished route spares ships the long passage around South America by way of Drake Passage, the Beagle Channel or Magellan’s strait.
