KARACHI – The progress on fifth signal-free corridor causes slow flow of traffic on the main city thoroughfare because of the lethargic attitude of the traffic police and wardens. Karachi Metropolitan Corporation (KMC) has started work on three flyovers at Shahrah-e-Pakistan at a time. The first flyover is being constructing at Water Pump intersection, second at Azizabad roundabout and the last one is in progress at Dakhana Chwok. Witnesses said that alternative u-turns and planning to divert the traffic was good enough but massive influx of heavy traffic, violation of traffic rules and irresponsible attitude of the traffic management authorities were reasons of traffic jam.People not even use the u-turn and move on wrong way that creates disturbance and traffic mess. Besides, Shahra-e-Pakistan is being used by heavy traffic including trawlers, intercity buses and other loading vehicles because the said road is directly linked to the Super highway.
