A Water passage to connect the Atlantic and Pacific Oceans became a passionate desire of Spain “from the year 1513 in which Núñez de Balboa discovered the Pacific Ocean.” When the search for a natural water route failed, Spain decided to build a canal. In 1528 Spain proposed to cut four canals through Middle America: from the Lake of Nicaragua to the South Sea, from the River Chagres to Panama, across the Isthmus of Tecoantepec (sic), and from Nombre de Dios to Panama. In 1800 she added two more possible canal sites to her list, from Rio Grande near Panama to Rio Chagres and from Rio Caymito to the Embarcadero of Rio Trinidad. But none of Spain’s plans came to fruition, and independence came to Spanish America without the construction of an interoceanic canal.
