ĐT.108 runs 22.6 miles between Sơn La and Điện Biên Phủ. We counted 1,319 corners along it, which works out at 58.3 a mile — corner after corner with no let-up. It runs past a river. That is busier than two thirds of the roads we have measured in Vietnam, where the median is 51.1 a mile.

Ridden together with ĐT.108 and ĐT.116 it makes about 50 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.
