A plea has been filed in the Supreme Court seeking that the Ram Sethu be declared as a national monument.
The PIL, filed by advocate Ashok Pandey, also seeks construction of a wall at the spot to facilitate devotees.
On March 20, the top court had said that it will list at the earliest a petition by BJP leader Subramanian Swamy seeking a direction to the Centre to declare the Ram Sethu as a national heritage monument.
Ram Sethu, also known as Adam's bridge, is a chain of limestone shoals between Pamban Island, off the south-eastern coast of Tamil Nadu, and Mannar Island, off the north-western coast of Sri Lanka.
Swamy had raised the issue of declaring the Ram Sethu a national monument in his PIL against the controversial Sethusamudram Ship Channel project, initiated by the UPA-I government.
The matter reached the apex court, which in 2007 stayed work for the project on the Ram Sethu.
The Centre later said it had considered the "socio-economic disadvantages" of the project and was willing to explore another route to the shipping channel project without damaging the Ram Sethu.
The Sethusamudram shipping channel project has been facing protests from some political parties, environmentalists and certain Hindu religious groups.
Under the project, an 83 km water channel was to be created, linking Mannar with Palk Strait, by extensive dredging and removal of limestone shoals.
