Ben Hansen, a civil engineer and pothole expert with the Seattle’s Department of Transportation, said it’s mostly because we have a “large backlog of streets that need to be re-paved.” Hansen said a brand-new road doesn’t get potholes because it doesn’t allow in rainwater. But as our roads age, they start to crack.
Why are there so many potholes in Washington?
It’s basic science. Water expands when it freezes. Water rains down on Seattle roads works its way into cracks and corners, then freezes and expands, breaking apart the pavement. Water also gets underneath the pavement and freezes, pushing up the road, breaking it up.

There are culprits. “If you want to blame somebody, first you have to blame the glaciers,” said local historian and Crosscut writer Knute Berger. “Because the glaciers retreated from the south to north, they gouged out the landscape and created a landscape where it’s really hard to travel east-west,” he said.
Why are potholes worse after snow?
Freeze + Thaw = Potholes
When temperatures drop overnight, the water freezes and expands, forcing the road to rise. Traffic then places stress on the weakened structure, widening existing cracks and allowing even more water to seep through.
Does ice cause potholes?
Water under road freezes and expands
Sometimes, when it rains, that water can seep below the asphalt. When freezing temperatures hit the water, under the road’s surface expands and stuff shifts around. And then when it melts, pressure from something, such as a car, can cave in the payment and create a pothole.

Salt and snowplows can make potholes worse. But blame time, traffic, temperature and precipitation for most asphalt pavement deterioration.
Why are there more potholes in winter?
temperatures and freezing nighttime temperatures can actually increase the number of potholes. With the constant shifts between melting and freezing, the streets you drive on may experience more stress and changes in temperature, thus resulting in more constant shifting.
How can we prevent potholes?
Preventing and Repairing Potholes
- Sealing. Crack sealing and slurry sealing keep water from penetrating the surface by sealing small cracks.
- Overlays. Overlays are a more intensive treatment in which a layer of compacted asphalt is constructed to seal the surface and add some structural strength.
- Reconstruction.
- Patching.
What is the main cause of potholes?
Potholes are holes in the roadway that vary in size and shape. They are caused by the expansion and contraction of ground water after the water has entered into the ground under the pavement. When water freezes, it expands. Think of when ice cubes are made.
