The bridge's unique curvature and composition by age reveals that it is man-made. Legend as well as Archeological studies reveal that the first signs of human inhabitants in Sri Lanka date back to the primitive age, about 1,750,000 years ago and the bridge's age is also almost equivalent.

The bridge currently named as Adam’s Bridge (most popularly known as Ram Setu) is about 18 miles (30 km) long.
This information is a crucial aspect for an insight into the mysterious legend called Ramayana, which was supposed to have taken place in tredha yuga (more than 1,700,000 years ago).
The bridge was purportedly passable on foot until 1480 AD when a cyclone moved the sand around.
Its unique curvature and composition by age reveal that it is man-made.
Because of the shallow waters, the bridge presents a problem in navigation, as big ships cannot travel in the shallow waters of the Pamban channel.
The discovery of this bridge is not only important for archaeologists, but it also gives an opportunity to the world to know an ancient history linked to the Indian mythology.
