We have one of the highest gas tax rates in the country, yet the worst roads. Just yesterday, I saw a guy get a flat tire from a chunk of pavement that had broken loose and was sitting on top of the roadway. I kid you not, the chunk was close to two feet square and a foot thick. Every day, I see potholes that are 8-10" deep with vertical walls. We have had times when they had to close bridges because the potholes were going all the way through and debris was falling on cars below. Michigan allows trucks to carry more weight than any other state. Many times, those trucks are full of trash coming over from Canada. Yep, it's cheaper to drive it across the border and dump it here than dump it in a country with vast amounts of wilderness. Ohio has the same if not worse weather and their roads are not bad at all. Also, we have more dirt roads than any other state. There are still dirt roads here right in the middle of very dense suburbs. I'm not talking farm land, I'm talking in cities! I really don't know where they hide all the road funds, but someone's getting rich! I laugh when people from Texas, or Florida whine about how bad their roads are. They would only have to come to Detroit once and they would never complain again. Sorry to rant. Bottom line, if your roads are good, go poly, if not, weigh the options carefully before choosing.
