• Wildlife migration

The term land bridge is sometimes used for wide bridges built over (or tunnels under) highways for wildlife and park users to cross. A natural crossing of a waterway is known as a natural arch or natural bridge.

• Ecology

A broader ecological use of land bridge is the geographic connectivity of habitats that allow animal migration, plant pollination and gene pool diversity afforded by a large connected ecosystem. In this sense rivers and forests provide some of the most common connectivity.
