FORT WAYNE, Ind. (WOWO): The sever winter storm is over, but leaders with INDOT are reminding drivers to beware of potholes on interstates, U.S. highways, and state routes.

The rise and fall in temperatures following last week's severe winter weather was a recipe for potholes to form quickly. As temperatures continue to rise and fall through the winter season, more potholes are likely to form.

Crews are filling potholes as quickly as possible, but with nearly 4,800 lane miles to maintain in the Northeast Indiana District, it is a big job.

Potholes begin when water seeps into the cracks in a road and freezes, expanding the layers of pavement, stone and soil beneath the surface. As the ice melts and contracts, heavy highway traffic further loosens the pavement, forming potholes.
