George Ballard died when he left the road at Dibbles Bridge and fell 15m. The bridge, which lies on a sharp bend in the road at the bottom of a descent, is a known blackspot: the previous year cyclist James Nelson died in an identical incident, and in 1975 a notorious bus crash resulted in 32 deaths.
In 2016 the bridge was modified to incorporate a safety barrier, which is now visible on Streetview.
