Work to repair a major road slip on Manukau Heads Road on the Āwhitu Peninsula is now
underway.
A spokesman for Auckland Transport (AT) said the 80-metre slip appeared during the early 2023 Auckland Anniversary Weekend flooding event, a few hundred metres from the Manukau Heads Lighthouse.
An estimated 90,000 cubic metres of soil moved during the slip.
AT expects the repair construction will take around four months to complete between 7am and 7pm, Monday to Saturday. The road will remain closed to all but residents throughout the construction.
The project, estimated to cost $4.1 million, includes building a new road and installing stormwater pipes.
More than 2000 slips were reported to AT during three extreme weather events: The Auckland Anniversary Weekend Floods, Cyclone Gabrielle, and February thunderstorms.
AT says the storms wreaked havoc on the Auckland Transport Network, causing major damage to roads (through slips, dropouts, pavement damage etc.), bridges, culverts, footpaths, bus stops, transport stations, streetlights, Public Information Displays, wharves and 29 cycleways.
Also in the Awhitu area, work on Kemp Road site 1 started in February and ended ahead of
schedule in March. Site 1 included a timber retaining wall and repairs to the road surface. Work on site 2 involves the installation of a soil nail retaining wall and drainage improvements and was expected to be completed by the end of April.
