First of all, there is 1 road which connects WL - Hanamkonda - KZJ and the city is spread around that road vertically. The width of the city is very less, only the length is more. People use share auto's more than bus. There is not much congestion in the city, why to use Metro ? PV is a great leader. But, keeping it to station is not good. Already airport at BZA ( gannavaram ) will be renamed as NTR airport after some time ( I am sure) .
