Which roads have been described.
Amber lines are roads riders have travelled; dots are potholes, speed bumps and rough stretches detected from their rides. Everything dark is road nobody has described yet.

This may take a little longer on a slow connection.
Every hazard here is detected from riders' phones, not from an inspection. It is unverified, and it gets better as more people ride.
