Utah State Hwy 14 from Cedar City East to Utah 89

'hairpin` turns on state and federal highways are rarely any tighter than a freeway cloverleaf, or urban intersection. On the tighter ones you might cross the centerline. There are a few state roads in California that length restrictions.

The main issue with 14 would be grades. It climbs substantially from Cedar City to the Cedar Breaks turnoff. 6000 ft to 9800. UT20 further north doesn't climb as high.
