502 — 須坂市 to 上越市

Japan · measured from OpenStreetMap geometry

502 runs 25 miles between 須坂市 and 上越市. We counted 1,189 corners along it, which works out at 47.6 a mile — corner after corner with no let-up. It runs past mountain peaks, a river, forest and woodland. That is calmer than two thirds of the roads we have measured in Japan, where the median is 53.1 a mile.

Ridden together with 498 and 391 it makes about 12 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.
