Work worth $1.6 million will close a significant section of Highcliff Rd on Otago Peninsula for 11 weeks to all but residents.
The Dunedin City Council yesterday announced work including the repair of three slips on the road, and installation of more then 1km of wire rope barrier by the Soldiers Monument, where the road runs close to a steep slope.
The work - from July 17 to September 29 - covers the area from Camp Rd, near Larnach Castle, to Seaton Rd, near Portobello.
The project will repair damage caused by three slips, two occurred during a 2015 storm in 2015 and the other earlier this year.
The road has been the site of 28 crashes between 2012 and 2016.
Council transport group manager Richard Saunders said yesterday one slip to be repaired was by the intersection of Sandymount and Highcliff Rds, another was on the city side of the Sandymount intersection, and a third a few hundred metres north of the intersection.
He said the use of wire rope barriers by the Soldiers Monument meant views would be retained.
In the past, part of the road had been closed by a gate to which residents had a key, but the closure to the public would not involve that method.
Instead, it would involve ''soft traffic management'' of signs warning the road was closed to the public.
The council would work with residents to inform them of what was happening, Mr Saunders said.
Council transport delivery manager Josh von Pein said an assessment of the road indicated the landslips occurred due to a combination of steep topography and poor drainage.
That could be expected on a road cut into the hillside well over 100 years ago.
Culverts in the road closure zone would be replaced, and the remaining low-risk culverts on other sections of Highcliff Rd replaced over the next four years as part of general maintenance work.
About 400m of timber guard railing would be installed on the outer edge of the road above steep drop-offs.
