Whole roads, not fragments: OpenStreetMap ways are joined into roads, walked one kilometre at a time, and every run of twisty kilometres becomes a stretch with a from → to. Paved, unpaved and flowing (sweeper) stretches are ranked separately by twisty kilometres. Click a stretch to see it on the map above.
