Portobello Rd will be closed during daytime hours next week while essential safety work to repair slips and remove damaged and dangerous trees takes place.
Dunedin City Council transport group manager Jeanine Benson said the work needed to be done to ensure public safety.
"The trees involved are deemed high risk, having been damaged in the October wind event, and need to be removed."
As a consequence, Portobello Rd would be closed between 9am and 4.30pm, from Monday until Friday.
"The road will remain open during peak travel times in the morning and evening.
"The closures will allow contractors to safely remove the trees, as well as clearing slips and other debris.
"Contractors will also carry out other scheduled maintenance, including vegetation control, street cleaning, channel clearing and sign maintenance, at the same time.
"By combining these tasks, crews can complete the work more quickly and reduce overall disruption on what we recognise as an important route for our community, visitors and tour operators."
The closures would happen in two stages, she said.
Stage 1 would run from Monday to Wednesday, closing the section from Marne St at the Andersons Bay causeway to Castlewood Rd, in Company Bay.
Stage 2 would follow on Thursday and Friday, closing the section from Castlewood Rd to Portobello township.
If there were weather delays, or extra work was needed, the road might be closed again on December 8 and 9.
"No through traffic will be allowed during closure hours, except for large vehicles such as buses carrying 25 or more passengers," she said.
"A detour via Highcliff, Camp and Castlewood Rds will provide access to homes, schools, shops and attractions.
"Bus services and DCC kerbside bin collections will operate as normal, and the Te Aka Ōtākou (Otago Vine) walking and cycle path along Portobello Rd will remain open."
Ms Benson said the council understood the work would be inconvenient for residents, and she urged them to be patient, understanding and respectful to the workers.
"We are doing whatever we can to minimise this, but there’s no avoiding the need to get this work done.
"Public safety has to be our top priority, and we’re also trying to be efficient — and minimise the impact — by carrying out other work while the road is closed."
