Ram Sethu, also known as Sethusamudram and Adam’s Bridge is a stretch of limestone shoals that runs from Pamban Island near Rameshwaram in South India to Mannar Island off the northern coast of Sri Lanka.
It formed part of a land bridge that joined Sri Lanka to the continent of Asia during the last ice age.
Hindu believers hold it as the structure that Lord Rama and his army of apes and monkeys built to reach demon king Ravana’s Lanka.
Ram Sethu is a continuous stretch of limestone shoals that runs from Pamban Island near Rameshwaram in South India to Mannar Island off the northern coast of Sri Lanka. Encyclopaedia Britannica says that geological evidence suggests that in the Ice Age, the stretch used to be a land connection between India and Sri Lanka.
There are different geological theories behind the origin of the ridge, one of which even says that Sri Lanka was a part of Indian landmass and that the calcareous rectangular blocks are testimony of Lanka breaking away from the mainland about 1,25,000 years ago.
Hindu believers hold it as the structure that Lord Rama and his army of apes and monkeys built to reach demon king Ravana`s Lanka.
The depth of the sea along the 30-km-long stretch varies between 3 feet and 30 feet, thus making navigation by sea-worthy vessels impossible in this stretch. Today, ships bound for India`s eastern coast have to circle around the entire island of Sri Lanka to reach Tuticorin, Chennai, Vizag, Paradip and other ports.
Therefore, a project titled Sethusamudram Shipping Canal Project was mooted by the Government of India and a feasibility study ordered in the 1990s.
In 1997, the Government decided to go ahead with the project but only finalised it in 2005. It calculated that successful completion of the project would cut travelling by about 350 nautical miles and will save 10 to 30 hours` sailing time. Plans were also drawn up to develop 13 minor ports in India, and fishing harbours and other infrastructure in both India and Sri Lanka.
The project has been condemned and opposed by a wide spectrum of the Indian people. Hindu outfits have come down on the plans to destroy something built by Lord Rama.
The project involves creating a 83-km-long deepwater channel that will link Mannar with Palk Strait by extensive dredging and removal of the limestone shoals that constitute the Ram Sethu. New Delhi thinks it will bring down shipping costs and add to India`s exchequer in the form of transit fees.
