  • High volume of vehicles passing
  • Road accidents: dump trucks, cargo trucks, buses, cars, and other vehicles regularly collide while traversing the length of the highway.
  • Lack of a proper drainage system often results in heavy flooding during the rainy season, effectively stranding commuters and damaging vehicles.
  • Public transportation vehicles are also known to stop in inappropriate areas to pick up passengers, which results in heavy traffic, if not potentially fatal vehicle collisions.
  • During collisions, the high number of people standing or walking along makes for pedestrian fatalities as well.
