Dear Friends, Each piece of land that connected India and Sri lanka submerged naturally, (and dispersed) to form the present day 'appearance' of a narrow strip. When each piece of land disappeared, the height of Tuticorin coastal area increased, and each time ports in this area shifted - means that, the material from these landmasses deposited along this seashore (Within last 2000 years). In this context, there is no need for a bridge to be built to go to Sri Lanka! You can just walk!
In another way if we consider, if we want to build such a huge landmass (approximately 21 kilometers with few kilometers wide and a kilometer deep,) we would have taken this mud from Rameshwaram coast. Can we pinpoint a place in Rameshwaram %u2013 from which place, that mud, stone and sand is used for this bridge? For instance, we have evidences in Tirunelveli from where stones were transported while constructing each temple in Southern Tamil Nadu (Mega Temples of Madurai, Tiruchendur, Tirunelveli etc.) Most of the temples in this belt used stones from Ambasamudram - Kallidaikurichchi Area. However, if we need stones to build a bridge - that you claim was built from Rameshwaram - the entire mountains of the agasthya hills are not sufficient!
