I did this trip in the month of June. I too drove solo from bangalore to Hyd- one word of advise- Do not drive on this highway at night. I left bangalore at 4 AM and between after yelahanka, when the road becomes single lane, it was pretty harrowing for the next 100 odd kms because that was the time all teh Volvos and trucks were streaming into bangalore.
the road surface is very good throughout, the only problem being that the highway is being widened to 4 lanes and hence there is a lot of construction activity happening.
one word of advise- after about 50kms from Anantpur, there is a Reliance one outlet. Stop there for a meal and to answer natures call because for almost 150 kms after that, the land is absolutely barren with not even a tree in sight and there is no place you can stop for a nature break- Just one practical tip, that i learned the hard way
travelling time whould not be more than 10 hours and if you are really upto it, you can do this in 8 hours if you time it well.
all the best and welcome to Hyd!
