Plans to build bridges to connect Wellington Island with Ernakulam and Mattancherry began in 1935.
Even at a depth of three hundred feet in the embankment there was no rock or solid surface in order to fasten the poles.
The foundation was fixed by driving iron pipes into the mud and filling them with stone and gravel.
From Ernakulam railway station, the heavy iron was transported over land and backwaters to the bridge construction site.
But on 24 February 2007, the same dredger hit the bridge again causing the rail traffic to be stopped completely.
