Pune to Solapur Road is in good condition.
Solapur to KA Border, road condition has improved drastically and is better. Naldurg is still bad and may take longer time for work to be completed. I recommend crossing Solapur to KA border during the day if you are driving Wagon R. I can recommend at night, with vehicles like like XUV or Creta or Duster or Innova.
KA Border to Hyderabad [except 2 diversions], road is again good.
I do not see any safety risk on Pune to Hyderabad stretch, if at all you are taking breaks at night; make sure you stop closer to Toll Plazas.
---------------Thank you Deepam! I agree with you constraint with Wagon R car. At night it will be difficult to drive on bad road conditions.
My plan is:
1. Leave Pune by 3.30pm after office
2. Night stay at Solapur
3. Leave Solapur by 6am next day morning
4. Reach Kukatpally, Hyderabad by 12pm
Thanks again !!!
