i dont know why kids are using internet nowadays.. let me tell you..the bridge was not built underwater..its was built over water(did u understand?) which got immersed due to rise in sea-levels over the years... dont u know y mathura city is found under sea today..did people biult it under the sea?? or in that case dhanushkodi in Tamilnadu built under sea??
All innocent kids who are asking these kinda questions can very well goto 3rd std and start studyng!! happy schooling..
