Roads are rarely called beautiful yet few would argue with that word for the A379 at Slapton Sands in Devon. It runs for miles along an elevated shingle bank with the English Channel on one side and a vast, tranquil freshwater lake on the other.

But the road is threatened by a combination of spring tides and easterly winds, which may mean the road will be swept away in the near future – and with it would go a lifeline for local residents and businesses.

“It would turn us into a dead end. No one would come here because it would be too isolated. We’d close down, everyone would close down,” warns Sally Pound, who runs the general store and Post Office at Torcross, the community closest to the road.

The road was breached by a storm in 2001. It closed for three months until a £1.2m repair realigned the tarmac 20 yards inland. If it is breached again it may be ”given to the sea” in line with official conservation policy but against the wishes of local people.

What was an eight-mile scenic run between Dartmouth and Kingsbridge will then become a 21-mile inland diversion along narrow lanes, many carrying buses and coaches in summer. Pretty villages such as Torcross and Strete will become more isolated and homes may fall in value as a consequence.
