National Highways Authority Of India [NHAI] — Bad road

Address: Raigad, Maharashtra, 410206

I was travelling by my own car from panvel to dombivli midc on 4/7/16. Immediately after crossing the toll (₹45 return) i met with traffic jam at about 9.35 am which was stand-still for about 90 mins. After that when i moved for about 500 mtrs, i found a huge pond in the middle of the road. The traffic cop was insisting to cross it. I followed a truck ahead of me. Somehow, the truck crossed the pond but my car being small, stuck into a ditch which was not visible.. The car was dragged out with the help of a rope tied to one of the trucks. My car is badly damaged. I incurred 6500/- expenses to repair the damage. While the car was stuck, traffic cop disappeared from the spot. With such a huge pond in the middle of the road, why the traffic was not diverted to the other side of the road? Who is responsible for the damage caused to my car due to negligence on the part of traffic cops and national highway authorities? Who will make good the damages?
