What is built on the isthmus that connects North and South America?
The Isthmus of Panama (Spanish: Istmo de Panamá), also historically known as the Isthmus of Darien (Istmo de Darién), is the narrow strip of land that lies between the Caribbean Sea and the Pacific Ocean, linking North and South America. The isthmus formed around 2.8 million years ago.
The Isthmus of Tehuantepec (Spanish pronunciation: [tewanteˈpek]) is an isthmus in Mexico. It represents the shortest distance between the Gulf of Mexico and the Pacific Ocean. Prior to the opening of the Panama Canal, it was a major shipping route known simply as the Tehuantepec Route.
- The heart of Seattle, largest city in the state of Washington, is on an isthmus between the city's chief harbor—the saltwater Elliott Bay (an inlet of Puget Sound)—and the fresh water of Lake Washington. Capitol Hill, First Hill, and Beacon Hill collectively constitute a ridge along this isthmus.
- The uterine isthmus is the inferior-posterior part of uterus, on its cervical end — here the uterine muscle (myometrium) is narrower and thinner. It connects superiorly-anteriorly to the complementary parts of the uterus: the body and the fundus.

- The northern part is dry, requiring irrigation for farming, and much of it is sparsely populated. The plateau rises as one moves southward, toward central Mexico. This is the heartland of the country--well watered, with fertile soil, and densely populated.
- The Panama Canal as it ended up being built has locks. This means that the Panama Canal rises and falls in elevation, which accommodates the natural geography of the Panamanian Isthmus. As originally designed by Ferdinand de Lesseps, however, the Panama Canal wasn't to have any locks.
- Building the Panama Canal, 1903–1914. President Theodore Roosevelt oversaw the realization of a long-term United States goal—a trans-isthmian canal. Throughout the 1800s, American and British leaders and businessmen wanted to ship goods quickly and cheaply between the Atlantic and Pacific coasts.
- President Theodore Roosevelt therefore supported the cause of Panamanian independence with the Canal in mind. His support paid off, and on November 18, 1903, the United States signed the Hay-Bunau-Varilla Treaty, establishing permanent U.S. rights to a Panama Canal Zone that stretched across the isthmus.
