India · measured from OpenStreetMap geometry

23.3Miles
63.7Per mile

NH510 runs 23.3 miles between Gangtok and Darjeeling. We counted 1,484 corners along it, which works out at 63.7 a mile — corner after corner with no let-up. It runs past a river, a waterfall, woodland and open water. That puts it in the busiest tenth of every road we have measured in India, where the median is 48.9 a mile.

Ridden together with Mongpu Road and H18 it makes about 23 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.
