39.8Per mile

EM 531 runs 10.8 miles between Terras de Bouro and Caldelas. We counted 430 corners along it, which works out at 39.8 a mile — consistently twisty. It runs past mountain peaks, a river, forest and woodland. That is busier than two thirds of the roads we have measured in Portugal, where the median is 30.2 a mile.

Ridden together with EM 531 and EM 535 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.
