Like many other heavily populated states, Pennsylvania sure does have its share of highways in very poor condition. I think most all states having major interstates and many large cities suffers with serious traffic overload damage. At least that's been my experience. Let's face it, the states aren't really building many new highways or interstate systems but we continue to significantly increase the traffic load with each passing year.
One example is to simply consider all of the additional FedEx and UPS trucks, both trailers and local delivery trucks, on the highways since the massive popularity of on-line shopping in recent years. Oh, and we all expect our order in a day or two! Another example is that virtually every family in the country has three and four or more cars on the road today. Let's face it, most of our highways were never expected to carry the traffic loads of today.
I could be wrong, but I really think one of the many reasons some roads get deferred today is due to the fact that most newer cars today ride so incredibly smooth and quiet that the roads don't seem so bad
Could be a different story if the folks in charge of highway maintenance would be required to test the roads in a motorhome
I sincerely hate driving on poor highways, but I try to understand a little bit as to how they get that way and the enormous financial challenge to maintain them. It costs a lot of money to provide both the labor and material to repair State and Federal Highways.
