• The bridge is a 48 km long chain of natural limestone shoals.
• Some of the sandbanks are dry, and the sea in the area is very shallow, being only 1 to 10 metres deep in places, whichhinders navigation.
• Geologic evidence suggests that Adam’s Bridge represents a former land connection between India and Sri Lanka. 
• Ram Setu is mentioned in the epic Ramayana, as the bridge constructed by Lord Rama and his vanara (monkey) army.

A strait is a narrow waterway between two pieces of land that connects two large bodies of water. Well-known straits include the Bering Strait, which links the Arctic Ocean with the Bering Sea and separates the continents of Asia and North America at their closest point. The Strait of Gibraltar, located between Spain and Africa, connects the Mediterranean Sea with the Atlantic Ocean. The Strait of Magellan lies between the southern tip of South America and the islands of Tierra del Fuego and links the Atlantic and Pacific oceans.
