Thanks bro. I had a thorough look on the same day and got the understanding. By reading through this DPR tender it is clear they are planning 4 bridges on Krishna within the range of 17kms.
1. N6 road(Tallaya palem) connecting Surayapalem( Part of Vijaywada proposed bypass-Dropped from Gammon india and still part of package 1&2 of the gundugolanu exention project) - Proposed in this DPR as well, but road connecting on other side of varadhi at existing Tadigadapa 100feet road.
2. N10 (Udhandarayuni palem) connecting Pavithra sangamam (Ibrahim patnam). Project work started by L&T.
3. The proposal bridge in this DPR connecting N13(Rayapudi) with mulapadu.
4. Another bridge part of Inner ring road (mostly road bridge on Vykuntapuram barrage) connecting Vykuntapuram with kethanakonda. Not part of this DPR tender.
So 4 bridges within the range of 17-20 kms. And this is except Outer ring road.
Not sure if these many required ?. They could drop the one proposed at N13(rayapudi), since the inner ring bridge is just 4-5kms away from this N13.
I hope they start Inner ring works as well, since the alignment and everything is done.
