I am not satisfied with decision of making vortical lift bridge near Pamban island.
Just like Crimean bridge, they must have raised the elevation for few 100 meters for ships to pass under it.
It...
more... will take minimum 20 minutes to lift up the verticals part of bridge and laying down back same.
So basically atleast 1 hour gap of trains is required for performing this action and allowing ship pass through.
Currently 12 trains daily cross the bridge and average 4-5 weekly trains cross the bridge daily. Traffic will increase more in future and this is the only option for transportation via sea a well.
