I lived in Mumbai for 6 years, though now living outside India and I know it is impossible for many contractors to survive without filling the potholes everywhere as the contractors who undertake the project likes to work every year and they make sure that exactly or even before the potholes are back. They create job for them by doing poor quality roads. Best solution will be if a pothole comes back within 3 years, then that particular contractor should lose any contract from the Government. People should feel the value of the job and that is something not to be taken for granted. if each and everyone feels the fear of losing the job, I know how hard people will work to maintain their reputation and the job of course. lesson to be learnt. Who is going to teach this? i would like to but how?
