Italy · measured from OpenStreetMap geometry

841Corners
23.1Miles
36.5Per mile

SS421 runs 23.1 miles between Caderzone Terme and Folgarida. We counted 841 corners along it, which works out at 36.5 a mile — corner after corner with no let-up. It runs past mountain peaks, cliffs, a mountain pass and a valley. That is calmer than two thirds of the roads we have measured in Italy, where the median is 49.2 a mile.

Ridden together with SS46 and SS300 it makes about 35 more miles of the same kind of road.

How we measured it

Corner counts come from the road's own geometry in OpenStreetMap, not from ratings or votes. Every bend above a threshold of curvature is counted once, so two roads can be compared directly. Nothing here is crowdsourced and nobody paid to appear.
