S513 — 南部县 to 仪陇县

China · measured from OpenStreetMap geometry

S513 runs 25 miles between 南部县 and 仪陇县. We counted 1,121 corners along it, which works out at 44.8 a mile — corner after corner with no let-up. It runs past a river and open water. That is calmer than two thirds of the roads we have measured in China, where the median is 50.6 a mile.

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.
