Isthmus

Wikipedia, the free encyclopedia - Cite This Source

An isthmus (ἰσθμός, plural isthmuses or isthmi) is a narrow strip of land that is bordered on two sides by water and connects two larger land masses. It is the inverse of a strait (which lies between two land masses and connects two larger bodies of water).

Isthmi are naturally good places to build canals. The Panama Canal, for instance, which connects the Atlantic and Pacific Oceans, drastically reduces the naval travel time between the east and west coasts of America.
