I don't know if this is representative of the whole US but I've just come back from busines in Florida. Drove from Miami to Sarasota (via Alligator Alley, didn't see any Gators) and back.
Overall I was very impressed with the roads. Smooth tarmac, well maintained and no potholes. Contrast that to England where on any mile of road you're likely to see a either a couple of potholes or some crappy fill in job which will last a year max.
