Pothole season has arrived early in Windsor.

City engineer Mario Sonego said the number of potholes in the city is “pretty normal,” so far.

“But it’s happened pretty early this year,” Sonego said. “There are some pretty good ones out there.

“Is it worse than last year? We’re not through winter, yet. So I have to wait until the end of the season, but there’s a lot.”

Sonego said the pothole season happens in cycles that coincides with the freezes and thaws throughout the winter.

“Water is the enemy of any structure,” Sonego said.

Water collects under asphalt, freezes, expands, thaws and the concrete or asphalt collapses, creating potholes.

“It’s more prevalent in asphalt roads,” Sonego said.

Crews, who normally plow snow from the roads, are now patching potholes on the midnight shift.

Sonego said the city uses “cold patch in the winter.” They aren’t as permanent as hot patches.

“In the spring … when the weather gets better, we go and do hot patches on the larger ones or the ones that aren’t stable,” Sonego said.

Sonego said a person whose car has been damaged by a pothole “can make a claim” with the city,.

“But I would never tell you to sue the city because I think we do a responsible job. We maintain our road system as best we can,” Sonego said. “I’ve managed to avoid them all."
