Notes and sources
Cycleway 9 is drawn from the 3 OpenStreetMap route relations tagged with its number in the June 2026 London extract our routing map is built from. Length is the sum of the mapped ways. Protected means a cycleway in its own right or a road with a mapped separate track. Quiet and lit are SuperSafe™ ratings from the Cyclemate London map over the 90% of the route it holds.
