Roads in the UK, compared with the US, are fantastic. I used to drive quite often from Chicago to Des Moines and after my first lousy experience on the I-80 in my Grand AM, I resorted to hiring a large Buick. Anyone who thinks that European roads are in ANY way comparable with US roads is utterly clueless on the topic.
The Eisenhower interstate infrastructure is brilliant as a road network, but it has never had the money spent on it that it needed for maintenance since it was constructed. It was treated largely as a one-time investment instead of the ongoing investment that any road is, and simply doesn't receive adequate funding to keep up with 50 years of wear and tear. Not that the problem is limited to the interstates, though. The problem is almost everywhere.
Oh, and the US road repair construction workers are the slowest workers anywhere on the planet. It is astounding how they can stretch 2 miles of roadwork out over an entire season.
