The Palk Strait (

Robert Palk, who was a governor of Madras (1755–1763) during the Company Raj
period.

The unique feature around Palk Strait is that the

Ram Setu is around 0.5 m.[3]

Geography and geology

Gulf of Mannar

Ram Setu or Adam's Bridge.[4] In Hindu Mythology, "Ram Setu" was created by the god Ram.[5] This chain extends between Dhanushkodi on Pamban Island (also known as Rameswaram Island) in Tamil Nadu and Mannar Island in Sri Lanka. The island of Rameswaram is linked to the Indian mainland by the Pamban Bridge
.

The strait is relatively shallow. The region around Ram Setu/Adam's Bridge is typically around 1–3 metres deep, while the central part of the strait is typically around 20 metres deep, with the strait reaching a maximum depth of 35 metres.[6]

Due to lowered sea levels during the Last Glacial Period (115,000-11,700 years Before Present) where sea levels reached a maximum of 120 metres below present values, the entirety of the relatively shallow strait was exposed as dry land. Following the rise to present sea levels during the Holocene, by around 7,000 years ago, the strait became submerged.[6]

History

In 1914, there used to be regular trains from Madras/Chennai to Dhanushkodi, a ferry to Talaimannar on Mannar Island, and then a train to Colombo. In 1964, a cyclone destroyed Dhanushkodi and the railway and caused severe damage along the shores of Palk Strait and Palk Bay.[7] Dhanushkodi was not rebuilt and the railway from Talaimannar to Mahawilachchiya in Sri Lanka was given up due to the civil war (It was later completely rebuilt). At least into the 1970s there was a ferry between small piers in Rameswaram and Talaimannar, but this was discontinued.[8] Ferry service briefly resumed around 2010 but at this time there are no passenger connections across the Strait.

Proposed canal

The shallow waters and reefs of the strait make it difficult for large ships to pass through, although fishing boats and small craft carrying coastal trade have navigated the strait for centuries. Large ships must travel around Sri Lanka. Construction of a shipping canal through the strait was first proposed to the British government of India in 1860, and a number of commissions have studied the proposal up to the present day. The most recent study of the Sethusamudram Shipping Canal Project, as it is now called, was an environmental impact assessment and a technical feasibility study commissioned by the Tamil Nadu government in 2004.[9]

However, the plan encountered opposition from various religious circles. The

Rama's Setu, was formed to prevent the shipping canal from being built.[10]

Fixed link

The construction of an Undersea Bed Rail tunnel linking India and Sri Lanka has been proposed that will pass below the Palk Strait.[11]
