I don't think the railway station is connected to NH16 directly or Ramavarappadu ring road junction Eluru busstop though the station and Junction are parallel but there is a canal and bridge is at east end of the PF and you it will be 1 to 1.5km and the station entrance building is on other side of road means level crossing. Anyone who is familiar with the geographical area and acess to rly stn can provide more info.
