The Highways Department of Chennai is fixing roads damaged by Cyclone Ditwah. Out of 654 km of roads under its control, 109 km had potholes. "We have been working at night and have completed repairs on 89 km of roads," said a source in the department. Waterlogging and constant vehicle use at certain places cause much damage. Roads near the Greater Chennai Corporation Headquarters on Poonamallee High Road, Mount Poonamallee High Road near Porur, Arcot Road in Valasaravakkam, VGN Nagar in Iyyappanthangal, and Thiruneermalai Road in Nagalkeni have been patched. "The patches are small or large, and in some places, paver machines have been used. Restoration of the riding surface is necessary to ensure better flow of traffic," an engineer explained. He added that many damaged spots lack storm-water drains. Due to road gradients, water from interior roads flows onto main roads. Though motor pumps were installed, waterlogging still occurs. T. Gunaseelan from Ambattur said, "They should ensure that waterlogging does not happen on major roads unless the rain is very heavy. There are still stretches without storm-water drains. The department should have constructed drains in vulnerable locations considering the fact that with global warming we are getting more rainy days with heavier rain." A contractor said, "In a city that faces monsoons regularly, potholes cannot be avoided. We only have to be prepared to take up repairs the moment rain stops." The repairs aim to make roads safer and smoother for commuters as Chennai prepares for future rains.
