The high road route on the Otago Peninsula has been plagued by closures and slips since the massive deluge which fell in June 2015.
Heavy rain this July caused further setbacks and closures.
However, the Dunedin City Council said it was expected slip repairs would be completed by mid-morning on Monday and the road reopened to all traffic.
‘‘The project includes repairing slip damage caused by heavy rain in June 2015 and July 2017, replacing culverts and installing guard rails to improve safety,’’ the council’s statement said.
‘‘Ongoing work to install guard rails and repair culverts is expected to be finished by the end of September.
‘‘Along with new signage and improved sightlines, the guard rails will make the road safer for residents and visitors.
‘‘Some continued traffic management — such as speed restrictions and stop/go signs — will be needed.’’
The work had cost $1.7million.
Further work on culverts on the road would be carried out as maintenance during the next four years.
‘‘The DCC is grateful for the patience and co-operation of the local community and tourism operators while the repairs are carried out.’’
