Waka Kotahi has provided a further update. It is anticipated State Highway 59 will re-open Monday 12 September if work goes smoothly.
SLIP CONTROL, PUKERUA BAY HILLSIDE SAFETY PROJECT: UPDATE 2 September 2022
Since Friday 26 August,excavators have cleared the unstable overhang above the slip face and relocated the spoil using multiple trucks. Excavators are working at the top and bottom of the hillside to remove vegetation and soil to create a slope that will be stable long-term, rather than do a quick temporary clean-up. Benches (steps) are being formed along the hill to capture debris, like the benches seen on the Ngauranga Gorge hillside. Approximately 15,000 cubic metres will need be removed – that’s over 2300 truckloads of earth – with 7000 cubic metres already having been removed as at Thursday afternoon 1st September.
Multiple crews are working 10 hours a day, seven days a week to complete the safety project in as short a time as possible to minimise the impact on people’s journeys. To minimise customer impact from our maintenance activity for the next year, the closure between Pukerua Bay and Paekākāriki has been used by many crews to undertake scheduled maintenance work, such as road and barrier repairs, high risk tree removal and pruning along with drain clearing.
Work has also started on making the Pukerua Bay lookout at the top of the hill safe, where two slips have undermined footpaths.
When can the road reopen to the public?
It is hoped that the road could reopen on Monday 12 September 2022, if all goes smoothly. The safety project team continue to assess the site daily to seek potential opportunities to allow limited public access past the site. Meanwhile the road remains closed to all users.
Occasional planned and carefully coordinated escorts for any train replacement buses is occurring when needed, to maintain this vital link for people. Limited access has also been maintained between Pukerua Bay and Paekākāriki for cyclists and pedestrians who are able to use Pukerua Beach to access the path at the bottom of the hill. However, they need to exercise caution for the uneven surface and high tides.
Thanks for your patience and understanding while this essential work is carried out.
