Great Britain · measured from OpenStreetMap geometry

369Corners
12Miles
30.7Per mile

A485 runs 12 miles between Cwmann and Llanfynydd. We counted 369 corners along it, which works out at 30.7 a mile — consistently twisty. It runs past mountain peaks, a river, woodland and forest. 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 B4343 and A485 it makes about 49 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.
