I want to draw the attention of the city district government towards a very sensitive issue of fast traffic on important roads of Karachi. This speedy traffic can be very dangerous for the pedestrians. Crossing the road can be quite difficult and for the elderly on busy roads it is next to impossible. I therefore, request the authorities concerned to construct speed breakers pedestrian bridges on all busy routes of Karachi so that everyone i.e. school going children, women, elderly persons, etc. can use them with convenience and without any fear.
