"Truck 30" was designated to follow NY 7 to NY 30A, bypassing that steep downhill segment, I'd guess several years ago now. I wouldn't be surprised if NY 30 mainline is routed that same way after this, truncating NY 30A to its NY 7 junction. I've driven up and down that hill many times and really enjoy the ride. But if you have a problem on the way down, whether it's mechanical failure, driver inattention, or driver incapacitation (which is the theory flying through the local rumor mill, no idea if that's reliable), it's bad news at the bottom.
