Why there are so many potholes

Watch out for pot holes as you drive around town. The warm weather and rain last weekend is making it difficult for city crews to get all the holes filled.

Potholes happen when moisture hits the pavement and it freezes. It causes concrete and asphalt to expand and become weak. When we get a lot of rain, like last weekend, all the weak areas fall apart at once.

Primary roads are the worst because they get the most traffic.
Peoria Street and Sewer Manager David Haste said, "Basically during the winter season it's a cold patch that we use and we fill the hole. There's not a whole lot of prep work. Hopefully the ground will be pretty dry so we can get the material in there and it will hold."

If you see a pot hole, try to safely avoid it and call your local street and sewer department to report it.
