Waka Kotahi has provided an update on the measures being taken to lessen the threat of further slips. This work is going to several weeks. The opening of Transmission Gully provides an opportunity to undertake remedial work that would be a far more difficult undertaking were the route still State Highway 1.
SLIP CONTROL, PUKERUA BAY HILLSIDE SAFETY PROJECT: UPDATE 26 August 2022
A hillside safety project is underway to help prevent further slips on the State Highway 59 coast road leading up to Pukerua Bay. Wellington Transport Alliance crews are removing a large overhang of soil and trees above the slip face to prevent further slips. A deep fracture in the ground behind the overhang at the top of the hill means this area is very unstable and could break away at any time.
The road between Fisherman’s Table and the northern end of Pukerua Bay has become a worksite and must remain closed for everyone’s safety, not just because of the risk of a slip but because of the machines operating in the area. The safety project could take some weeks, depending on conditions. The hillside diagram, shown over the page, illustrates the overhang and the fractured ground and highlights the work that is planned to reshape the hill and prevent further slips.
Multiple works, including road and barrier repairs, tree pruning and other maintenance, are taking place to make the most of the closure.
The hillside is being inspected daily to assess when pedestrians, cyclists and vehicles can be allowed back in the area. Meanwhile, pedestrians and cyclists can use the Pukerua Bay off-road beach walking track to bypass the works but must exercise caution for high tides and weather conditions. The soft beach sand and the slope leading up to the layby at the bottom of the hill make for difficult going, particularly for cyclists. A fenced-off path has been created around the layby to keep path users safe from moving machinery. The path beside the seawall north of the layby can be used and we ask people to stay on the path and not to walk or cycle on the road as work trucks and machinery are using the area.
