The Iowa DOT is warning drivers the up and down temperature changes are making conditions right for potholes to grow on roadways. DOT district engineer Bob Ellis says potholes usually appear in spring with the warm days and cool nights.
Moisture that is okay when its warm, freezes when it gets cold and expands to widen out small holes. Ellis serves District 1 in central Iowa and says it doesn’t matter if a road is asphalt or cement.
Ellis says they can put a temporary patch in the potholes to lessen the impact for cars.
He says the fix works until spring.
We haven’t had a lot of snow so far this winter, which is one positive.
Ellis says if you see a pothole forming on a state highway, you can go online and report it to the district office where the highway runs.
