Isthmus


Isthmus

An isthmus is a narrow strip of land connecting two larger land areas. Many canals are built on isthmi where it is particularly advantageous to create a shortcut for marine transportation. Of note is the Panama Canal, which connects the Atlantic and Pacific Oceans, and drastically reduces the naval travel time between the east and west coasts of the Americas.
