Just 0.9% of the minor road network is resurfaced or strengthened each year, and a further 3.1% is surface dressing, down from double that figure 20 years ago. The failure to maintain the roads has led to the growth in potholes reported by local authorities over recent years.
Potholes are dangerous, even lethal, for people on bikes.
But fixing potholes is a huge waste of resources: each pothole costs over £50 to mend, and the number of potholes has massively increased in recent years.
Meanwhile, that pothole is often a symptom of an underlying structural weakness in the road, or a failure to keep water out of the surface.
