The main byways connecting cities in AZ, NM, CO, and UT are generally well maintained, especially in AZ, CO and UT. Some of them require repairs every year above 6,500 ft elevation. Some of the lesser known and lesser used paved roads in the high country surrounding entirely by US NF (national forest) do get moderately damaged from winter freezes/thaw cycles and heavy snowfall and rockslides in both winter and monsoons, they just get closed down from November to May usually. I know of a couple stretches in AZ that are potholed to hell (pic not related), but the state does a decent job of repairing them every summer, only for them to return next spring. The I-40 between Flagstaff and Williams AZ averages 90 inches of snow a winter (the most in the US for a major highway not passing through the Rockies)and has an armada of snowplows to keep it open every storm because it is main national transport artery from the west to east coasts. Monuments and national park infrastructure costs a lot to maintain because it has the highest traffic bar none among US public lands, like literally 5-100s of times more traffic than NF areas. Most of the roads in the South Rim Grand Canyon have been totally resurfaced within the last couple to few years at most, and it only gets 30-80 inches of winter snowfall. I'm not saying the government doesn't waste money, but that it is easy to waste money with just upkeep costs.
