They will rebuild a new bridge keeping in mind the new proposed 5th and 6th line between Kuala and cstm. There are few more in pipeline. After Hancock it will be carnac bridge, Olivent bridge, trambyculla, garden bridge, arthur bridge, carol(CR+WR portion at Parel and elphinstone road), sion and nahur. Carnac bridge is the next. All other bridges would be a headache for railways traffic police as well as general public if taken up in future.
