The A57 Snake Pass is the responsibility of the Derbyshire county council as local highways authority.
I understand that the road was closed in the interest of road safety for a period of three weeks following a land slip which affected the road surface.
Following a period of stabilisation the road has been reopened with a 10 mph speed limit. Derbyshire county council is continuing to monitor the situation and, if no further movement occurs, will carry out resurfacing of the road in late spring.
