How it rides
29 corners over 17.8 miles — 1.63 a mile, and 176° of turning for every mile ridden. That scores CS-4, Twisty on the five-point curviness scale. 46% of those corners are sharp ones, and the road reads as tight.
What it climbs
The road climbs 963 feet in total, 54 feet per mile, between 718 and 1,059 feet — 342 feet of relief. The longest single climb is 216 feet over 0.7 miles, and the steepest grade on it is 10.5%. For this country that is relentless.
Surface, speed and traffic
Paved end to end. 85% of it is back road rather than highway, the other 15% state or US route. Posted speeds run to 55 mph, typically 55, measured across 37% of the route. State traffic counts cover only 2% of these miles, too little to put a number on, which is itself a fair sign of how quiet they are.
