I hereby want to draw your attention on a very serious issue concerning public safety.I am regular traveller on NH53 to Nagpur via lakhani and SAKOLI I am having a problem with flyover which is under construction in Lakhani.The contractor is not taking proper measure to ensure public safety.On my way to Nagpur while passing under a bridge loads of cement has been dropped on my Vehicle that cause permanent damage and nobody is there to listen.I hereby urge concerned officials of NHAI to look into the matter before any major thing happen that cost human and compensate the loss caused to me.
