New Delhi, Jan 31 : The Supreme Court has granted four weeks time to the Centre to file its affidavit on Sethusamudram project on Thursday.
Juctice K G Balakrishnan headed the bench.
Next hearing on the matter will be in the first week of March.
The Bharatiya Janata Party and other Hindu groups have called on the government to stop the Sethusamudram Ship Channel Project, saying it will demolish the mythical bridge linking India and Sri Lanka, believed to have been built by King Ram of Ayodhya.
Opposing the 560 million dollars project, the Hindu groups claim it would destroy the 48- kilometre chain of limestone shoals that once linked Rameswaram in Tamil Nadu to Mannar in Sri Lanka.
The Sethusamudram Project will dredge a channel along a narrow strip of sea between India and Sri Lanka, reducing distances and cutting costs for freight traffic.
According to the Central Government, the sand shoals were created by sedimentation.
Dredging for the project began in 2005 and the channel -- 12 metres deep, 300 metres wide and almost 90 km long -- will provide a crucial link between the Palk Bay and the Gulf of Mannar.
