A good road that would be better with newer pavement, as of 5/2021. You go up to above 5,000 feet, so be prepared for a temperature drop, if you're on a motorcycle. The traffic is fairly light, though there seems to be a fair amount of people at the top.
My YouTube video will tell you more than I can. (And there's hundreds more videos where that came from.)
