A busy north Dorset road will be closed from today for resurfacing.
Zig Zag Hill on the B3081 will be shut until Friday, with the C13 through Melbury Abbas also remaining closed.
A Dorset Council spokesperson said: "Resurfacing Zig Zag Hill presents difficulties not only with the nature of the road itself but also with the depth of the reconstruction needed.
"It's due to these deep excavations that the only safe way to carry out the work is under a full 24-hour closure – it is just not safe to reopen the road between shifts.
"The road is being resurfaced from White Pit Lane up to the top of the hill.
"The C13 through Melbury Abbas has been closed since January for a new pull-in and vehicle activated signs (VAS) to be installed for HGVs travelling through the village, as part of Dorset Highways’ A350/C13 route management scheme.
"Although the resurfacing through Melbury Abbas will be finished on Friday, 17 May, work is continuing to put the new signals into operation.
"The decision has been made to keep the C13 closed while surfacing Zig Zag Hill to avoid diverted traffic using the C13, rather than the signed route on the A350.
"The C13 and B3081 will reopen together at the end of May.
"Dorset Highways will then assess the surrounding minor roads for repairs caused by diverted traffic using them during the closures."
