Work for a diversion road to help protect a limestone gorge which contains the country's oldest cave art has been given the go-ahead.
Derbyshire County Council and Lafarge Aggregates Ltd have agreed to fund the £1.2m scheme for Creswell Crags.
A section of the B6042 Crags Road - which runs close to the Ice Age cave system - will be replaced by a new 1km stretch of road 200m further north.
The old road will be turned into a bridleway for walkers and cyclists.
Councillor Brian Lucas, cabinet member for sustainable communities at the council, said: "The unique archaeological features at Creswell Crags date back between 10,000 and 50,000 years.
"We can't stress enough how important it is we preserve this site as best we can.
"And the new road will help protect the environment around the Crags by cutting down on traffic noise and pollution."
