Sethu Samudram

The Sethusamudram Shipping Canal Project proposes linking the Palk Bay and the Gulf of Mannar between India and Sri Lanka by creating a shipping canal.

Sethu Samudram is the sea that separates Tamil Nadu, India from Sri Lanka. It encompasses the Gulf of Mannar the Palk Strait, and a shoal of islands and bays that separate them called Adam's Bridge.

The sea is quite shallow, with a depth of less than 10 meters across most of its extent. Much of its seabed consists of limestone rock. It formed part of a land bridge that joined Sri Lanka to the continent of Asia during the last ice age.

The coast of India does not have a continuous navigation channel connecting the east and west coasts. Currently the ships coming from the west coast of India and other western countries with destination in the east coast of India and also in Bangladesh, China etc have to navigate around Srilankan coast. The existing water way is shallow and not sufficient for the movement of ships. This is due to the presence of a shallow region known as Adam’s bridge, located southeast of Rameswaram near Pamban, which connects the Talimannar Coast of Srilanka.

Due to these factors, the ships originating from west of India and destined for Chennai, Ennore, Vishakapatnam, Paradeep, Haldia and Kolkata have to travel around Srilankan coast resulting in increase of travel distance and time. Apart from these ships belonging to Indian Navy and Coast Guard need also to traverse around Srilanka.
