The scriptures and beliefs in Hinduism throws light on a fact that the Ram Setu is said to have been built by Lord Rama and his vaanar sena seventeen lacs twenty five years ago to go to Lanka and rescue his wife Sita from the demon king Ravana . This is narrated in the great Indian epic Ramayana. Often taken as a myth, the discovery of Shri Ram Setu by NASA confirms the Hindu scriptures and belief are correct in this matter and that Ramayan is not "mythology" as is often construed but "history". The Setu is situated southeast of Rameshwaram, connecting the Talaimanar coast of Srilanka.

According to the scientists, a sea route may be prepared for navigation without damaging Sri Ram Setu, by removing the barren sand heaps near village Mandapam between Rameshwaram and Dhanushkoti railway. This will not only give a shorter route for navigation but also protect the oldest man-made heritage.

Setu Samudran ,a shipping canal project has been approved by the Government of India to be set up near Kodand Ram Temple. Making a shipping canal through Rameshwaram Island in this project will link the Palk Gulf and Gulf Mennar. This will enable ships and boats to navigate in the passage between India and Srilanka and will also save about 400 marine miles voyage on the west coast.

The National Sea Route will be connected with this project. It will also connect the National highways. This canal will not only shorten the length of the sea route for ships but also will aid in saving the fuel costs of the ships. According to the researchers approximately Rs. 21 crore per year for fuel expenditure of ships will be saved. Today, India imports a big quantity of crude oil and with this project fuel will be saved which in turn will save foreign currency. The time that the ships take will also decrease by 16 hours and therefore the numbers of ships navigation will also improve.
