Great Britain · measured from OpenStreetMap geometry

B3399 runs 12 miles between Portsmouth and Southampton. We counted 349 corners along it, which works out at 29.1 a mile — consistently twisty. It runs past the coast, mountain peaks, cliffs and a beach. That is busier than two thirds of the roads we have measured in Great Britain, where the median is 23.4 a mile.

Ridden together with A3056 and B3401 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.
