fool guest,RAM sethu is useless project.Todays shipping industry talk of only 30,000 mts and up ships which can not transit through sethu channel as its depth is less than 10 meters.also pilotage cost,dredging every year will cost more besides,towage boats,investment cost and unviable trade traffic in that region will make this project uneconomical.it is like a veeranam project,coovam beautification project started by DMK govt.do you want to waste public money?
