WESTBROOK, Maine (NEWS CENTER) -- The long Maine winter has left some roads in rough shape -- and it's not just potholes.
Frost heaves are popping up on rural roads, such as New Portland Road in Westbrook.
Frost heaves form when ice builds up beneath the surface of the soil. The bumps on the road can contribute to pot hole growth.
Car mechanics say driving too quickly over them can blow out tires, damage, or even break wheels, and disrupt alignment.
Those kind of repairs can cost hundreds of dollars.
"We try to take it easy on the tire costs because it's an unexepcted cost and that's the hardest part," said Heath Lovely, of Tire Warehouse in Portland.
His advice: drive slowly and avoid frost heaves and potholes if possible, and have your car aligned twice a year.
