Though there may be other contributing factors, potholes are generally created when water gets into the base material of the road, weakening the structure. Traffic moving over the poorly supported asphalt surface then causes the road to begin to disintegrate, creating potholes. Since ACHD’s creation in 1972 our goal has to been to respond to potholes within 24 hours. If you happen to find one, please let us know and we will take care of it.
