In November, it was reported the road had slumped due to a slip the Dunedin City Council had been monitoring.
The council said at the time geotechnical investigations and design work were being done to deal with the issue.
Asset and commercial manager Merrin McCrory said yesterday initial work to stabilise the site was done in November and December and the permanent repairs began in February.
A small section of Morris Rd had been closed, with a detour along Coach Rd.
''We have chosen this approach to keep the work site safe and to protect properties and council services, such as pipelines, in the area.''
Miss McCrory said a contractor was excavating 2m to 3m below the road to remove material from the top of the slip, constructing a toe buttress to stabilise the slope, then reconstructing the road to previous levels with a widened shoulder to allow for future pedestrian and cycle use.
The work was expected to cost $750,000.
Morris Rd would be open to traffic by April 13 with some work to tidy up Coach Rd scheduled for one to two weeks after Easter.
