Some other synonyms for land bridge are isthmus, strip of land, causeway, connection, and link. A well-known example of a land bridge is the isthmus of Panama, which connects North and South America. Other examples include the Kra Isthmus in Thailand, the Isthmus of Suez in Egypt, and the Isthmus of Tehuantepec in Mexico.
