The 180m-long wall will repair damage caused by a landslip at Turnbulls Bay in last year's June storm.
The storm also caused a major landslip on Upper Junction Rd at Sawyers Bay and a significant slip in Brown St in central Dunedin.
Dunedin City Council projects engineer Evan Matheson said computer-generated images of what the 2m to 4m high wall at Turnbulls Bay should look like were given to the Otago Peninsula Community Board this week to update members on progress since the slips. A section of the road around the bay has been reduced to one lane, managed by traffic lights, since the slip occurred.
Board chairwoman Christine Garey said the Broad Bay community had been ''extra patient'' over the inconvenience so far, although the length of time it was taking to come up with a solution had been concerning some residents.
People would need to wait a bit longer, but their patience would pay off.
The repairs would also include widening the existing road to include a 3m-wide shared path for cyclists and pedestrians, which had not been part of other, future, plans to improve the road.
''It's a plus. And it's going to be later than people wish, but that's the reality.
''The staff have been working very hard on this.''
Mr Matheson said the price of the wall was indicative until a design was confirmed, but at this stage the whole project was expected to cost between $750,000 and $900,000.
The council would pay for part of the work from its storm events fund and expected to receive funding assistance from the New Zealand Transport Agency for the rest.
Mrs Garey said the engineering could not be changed, but the community's feedback on the texture and colour of the wall was needed by February 20.
Detailed designs would then be done, with construction to begin between July and December.
Construction work was expected to take two months, with one lane to be kept open during the work.
