The Illinois Department of Transportation is advising the public that maintenance crews are out patrolling and repairing potholes on state highways and interstates across the state, requiring drivers to slow down, use caution and move over for workers.
Recent heavy snow, rains and freezing temperatures have caused an increase in potholes throughout the state. Potholes typically are caused by water getting into or underneath the pavement. During freeze and thaw periods, the moisture causes the asphalt or concrete to shift, buckle or break.
