I know about this route very well my friend, you dont have to worry about that! I am from Hyderabad and travel way too often. Anyway, yes work is pending at the alignment of bridge at mantralayam road and that is the only stretch(Mantralayam road-Matmari) which is not doubled between GTL-SC yet, i agree hence i said technically not fully double. As far as the electrification is concerned, poles are up from either sides(From wadi side and GTL side) upto Yadgir and intermittently pretty much everywhere but there seems to be no likelihood of completion of electrification atleast till 2016 end or early 2017, for example look at YNK-GY, electrification started more than 2 years ago and is not complete yet.
