Hot weather has caused some Missouri highways to make bumps in the road and shoot asphalt into the air. Stacy Covitz has the story from Jefferson City.

Some parts of Missouri highways have been buckling in repeated days of high temperatures.

Department of Transportation spokesman Jim Coleman says when the pavement is under too much pressure, it expands.

Contents: Coleman says if the pavement expands too much, it will blow up. Sometimes this makes a bump in the road, and sometimes pavement will shoot into the air.

Coleman says that is the exception rather than the rule. He says there is no way of knowing when the highways will expand. From the state capitol, I'm Stacy Covitz.
