Des Moines, Iowa – The freezing and thawing have been brutal on city streets opening up large potholes. Iowa DOT Winter operations administrator, Craig Bargfrede says state highways have not been immune from the problem.
Water from melting snow is the culprit as the temperature drops at night and causes it to expand.
The potholes can be seen and sometimes avoided before they cause damage to your car.
Bargfrede says another problem caused by the melting snow often is not seen until its too late.
The black ice can cause your car to skid and go out of control. Bargfrede says they try to get to it as soon as they can.
Bargfrede says potholes and black ice are not the only thing you might encounter this time of year — so he says you should always be aware of changing conditions.
And he says the rain and melting snow have caused water to cover many roadways and you should always be careful in flooding situations too.
