Waka Kotahi has advised there will be two sets of works being undertaken in the next few days.
Sunday night (6 August 2023), a road repair will be done on SH59 near the corner of Wairaka Road. This was notified to the neighbours for Thursday but weather has pushed it out to Sunday – also weather permitting.
Monday night (7 August 2023) the watermain service lid at the intersection of SH59 and Gray Street will be lifted and given a concrete surround to make it level with the road. Service lid lifting is something that a team travels the highway network doing some time after road repairs and resurfacing jobs have been done. It can’t be done at the time of the works because of the extreme heat of the asphalt when it is laid.
Good news to all those who drive into Gray St from SH59. Waka Kotahi has advised that, subject to weather conditions,work will be carried out to fix the intersection, removing the somewhat bumpy surface and replacing it with a smoothe one.
The work will be undertaken on Sunday evening and will not take all night.
Waka Kotahi has apologised for the time it has taken to fix the intersection.
The entrance to Gray Street from SH59 is on the PCC books for remediation over summer. As anyone driving over it will know the rate of deterioration seems to be increasing. Remediation works, digging out and are dependant on the ground under the new material being dry enough to be consolidated and ready to be asphalted. The road has been marked out for some time in preparation for the works.
SH 59 will not be re-open on Monday 12 September. There is more work to be undertaken. Waka Kotahi has provided the below up-date
Crews are working 24 hours daily to get State Highway 59 between Pukerua Bay and Paekākāriki reopened next week.
As of this morning, Friday, 9 September, 19,000 cubic metres, approximately 2500 truckloads of earth has been removed from the site as part of slip remediation, and slope benching works. Another 6,000 cubic metres, almost 800 truckloads, is to be removed this weekend.
Weather permitting, earthworks will be completed early next week.
The final part of the operation will be clearing the work site, installing edge barriers and reinstating the road before reopening safely to the public, which will take an additional 2-3 days.
On Monday, 12 September Waka Kotahi will provide an update on the expected timeframe for reopening the road.
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.
The next update on the re-opening of SH59 between Paekākāriki and Pukerua Bay will be provided on Friday 2 September. From Wellington NZTA:
The hillside continues to be assessed daily to ensure safe access to cyclists, vehicles and pedestrians can be restored. Residents can continue to access Pukerua Bay from the south and Paekākāriki resident access is from the north. All other road users to continue using SH1 as an alternate route.
We know these works are inconvenient and thank the community for their patience!
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.
State Highway 59 between Paekākāriki and Pukerua Bay will remain closed until further notice.
The highway has been closed since Friday, 19 August after multiple slips. Further assessments over the weekend determined the slip site remains unpredictable. Making the site safe is a significant job, and it could take several weeks before it can reopen to traffic.
Now that work has commenced cyclists and pedestrians will not be able to pass through the wider worksite, due to the ongoing risk of material falling from the slip site and heavy vehicles and machinery moving around the wider area.
Additional barriers and fencing will be installed at the northern end of Coast Road, across the road at Fisherman’s Table and the southern end at the Pukerua Bay bottom carpark. We ask all pedestrians and cyclists to avoid the area please.
As work progresses we will review each stage to determine whether it will be safe to pass through, and we will provide updates. This work is likely to take several weeks, which we appreciate is inconvenient for locals, but your safety is our priority.
