Now that most of the snow has melted from our roadways I've noticed an awful lot of potholes....why does this happen? Why this year in particular?

We had a large of snow dumped on us, when it starts to melt off the water seeps into weaknesses and gaps. The water enters into the ground under the pavement. When water freezes, it expands.As the weight of vehicles pass over the weak spot in the road, pieces of the roadway material weaken, which will cause the material to be displaced or broken down from the weight, creating the pothole.

Makes sense....sooooooo when are they going to get fixed? plan on seeing detours everywhere when the weather warms up.
