Don't know about your state/area, but in PA near Philly (like a radius of 150 mils out) there are MASSIVE potholes everywhere. I'm talking about foot or two feet wide and 6" to 2' deep.
I have seen two places where the macadam around a manhole has entirely been ripped away and it has started to fall into the sewer before a repair crew showed up. I destroyed a rim and tire on xmas. I saw/heard a car hit one of the nasty ones and could hear the tire pop on one guys car. I routinely have to drive like a complete idiot, dodging massive numbers of huge deep potholes densely packed like driving through a minefield while everyone behind/in front of me doing the same.
Anyway, there have always been potholes in the winter, this is nothing new. The thing is, I have never seen anything like what I'm seeing this winter. Literally, with zero exaggeration, 20 times the number of potholes than normal, and very often on roads that were just totally resurfaced less than 10 years ago. Also, they go from say 2" x 2" to 1' x 1' in maybe a week. The breakdown is so so fast.
I can't find much on line, and honestly it's seemed like most people are unaware that it's worse than ever before. But the question remains, Why? Why is this happening this winter?
