The A623 between Stoney Middleton and its junction with the B6521to Eyam is closed this morning, following a rock fall late last night.
A full inspection can't be carried out until daylight arrives.
Diversions are in place there.
We've had to close the A623 between Stoney Middleton and its junction with the B6521 to Eyam following a rock fall. A full inspection can't be done until daylight which means the closure will affect the morning commute. Diversions are in place.— Derbyshire CC (@Derbyshirecc) November 13, 2019
