It’s quite costly to go srilanka today from Tamilnadu in South of India. Because only flights are available and they cost more than 100USD which is unaffordable for many in India. However if a land bridge exists, folks already on religious tourism trip in South India can go to srilanka for cheap. This should boost both Srilankan tourism and also Indian trade to Sri Lanka as freight will become cheaper as well.
This is very informative. Thank you for such a great write up.
