Yes the bridges on River Godavari are longest bridges but the line cannot be a gamechanger for India or the GT line. Yes it will connect Konaseema region with the mainland whcih is not connected by rail till now. Trains will originate from Kakinada travel to Konaseema and will be connected to BVRM line and you can get a direct connection to Hyderabad and few day time trains intercity upto VJA..
