73 Bethells Road, Near Steam Hauler Track

30 April 2024

Work continues on the under slip ahead of building a 30m long, 2m high stone wall to support the road.  

Over 500m3 of material has been removed from the site. Our team are currently working on the base block platform and will be installing the blocks next. We are on track to complete this, weather dependant by mid-May 2024.

160-198 Bethells Road

AT will be working to repair storm related damage at this site. This work includes matting and hydro-seeding.

Caton Road, Waitakere

30 April 2024

The second of three stages of piling and anchoring is complete, and the drainage works have begun with the installation of the first manhole for the culvert crossing.  Works are due to be completed in mid-May, weather dependant.

We are making good progress despite the challenging weather and have started working on Saturdays to increase weekly productivity.

13 March 2024

Works are progressing on Caton Road, and the team from Ventia have been installing the anchors that stablise the road, and the piles (steel beams). The retaining wall will be built with the support of the beams.

On advice from Geotechnical Engineer and for everyone’s safety, a 3.5 tonne vehicle restriction will apply until the repair works are complete. There are large materials being delivered to site which require a temporary closure, during this time traffic will be stopped by traffic controllers to allow work crews time to safely stop and clear the road of plant and equipment. There is a white board at the entrance on Caton Rd to show when these deliveries are expected.

Access restrictions apply:  A vehicle weight limit of 3 Tonnes applies through this site.

Glenesk Road, Piha

30 April 2024

Works began on Glenesk Road on 25 March 2024.

Downer on behalf of Auckland Transport (AT) will be constructing are undertaking slip repair works outside numbers 7 and 19 Glenesk Road. This involves the construction of a retaining wall, repair of the footpath and shoulder. This work is required to stabilise the area and prevent further slips and damage occurring.  

Work is progressing well, and is on target to be completed on time.

The road closure with resident only access will remain. This will enable our team to safely carry out work. Parking restrictions will also be in place, please follow all signage and directions from traffic management team.  

Karekare Road

28 February 2024

We started works on Karekare Road, between Piha Road, and the bridge at the Regional Park, on 16 October 2023. Works on these sites are almost complete.

We started works on Lone Kauri Road on Monday 12 February 2024. While works are underway, we will need to close this road. All traffic will need to go via Karekare Road.

Please note we have one more slip site to complete on Karekare Road, after we have completed works on Lone Kauri Road. We will notify the community before we start these works.

Huia Road - Various sites

30 April 2024

There are a number of slip sites along Huia Road including:

• 81 Huia Road
• 370 Huia Road
• 634 Huia Road
• 100m past Cornwallis Road
• 100m past Kaitarakihi Road

Designs options have been investigated and presented for the repair of these various sites. The options are currently being considered by the team. Each site will have a separate design for the repair work.

We will update the community before works start on any of these sites. 

Kay Road, Waitakere

Closed - Residents & Emergency services access only from Waitākere Road end.

Work is underway on the repair design.

While are unable to give a specific timeframe on repair works, we aim to have this work completed in 2024, to restore this connection for the community.

Kellys Road, Oratia

30 April 2024

The design for the repair at Kellys Road is currently being reviewed. Works are anticipated to start in May 2024.

Konini Road, Titirangi

30 April 2024

We are working on the investigation phase, to confirm what solutions are available to repair the under slip on Konini Road.

After investigation is complete, we will be working on the design of the repair. 

Lone Kauri Road, Karekare

30 April 2024

We are continuing major slip repair works on two sites on Lone Kauri Road between Piha Road and La Trobe Track. We have completed all of the soil nailing at these sites and are working on completing the work on the road, shotcrete (spray on concrete), drainage and guardrails.

The road will be closed during the day, and open after work hours to residents only.

This will be a full road closure during work hours, we will be unable to open this site for school drop off or pick up.

 14 March 2024

Work is on programme with the majority of the soil nails having been installed for this site.

In the next couple of weeks, we are completing the final rows of nails before moving into drainage and road reinstatement works.

Mahoe Road

The repairs the damage at 22 Mahoe Road, were completed in December 2023. 

The works included removing the damaged section, rebuilding the retaining wall and repairing the road. 

McEldowney Road

10 April 2023

Partial lane closure - drive with care.

Mountain Road

19 March 2024

We have been working with the contractor to review the timeline for the works on Mountain Road, as we would like to be able to get this connection open sooner for the community. We have settled on a timeline, that anticipates the completion of these works by end of December 2024. This will be achieved by a second work crew being available to work on this location.

There are factors that have to be considered:

• We will only be able to work at two sites at any given time on Mountain Road, due to narrow nature of the road, and the access through the sites.
• In some cases it will be more difficult to work two sites at once for safety reasons, due to the layout of the road.
• The availability of the second works crew is yet to be confirmed, currently estimated to be available in June.
• Each location must have the design approved before works can start, there is still work ongoing for some of the designs.
• Although we have built some contingency into the timeline, weather and other factors can cause some delays.

5 March 2024

After starting work at Mountain Road, we have found that our design was not going to fully meet our needs, and as a result we are had to pause to redesign some components of the wall. Despite everyone’s best efforts this does happen sometimes, and it is took longer than anticipated to finalise the technical issues involved.

The redesign work has progressed to a point that we can announce a target start date of 2 April 2024. This is later than we had hoped but some issues can be very complicated to solve and we appreciate your patience.

Works on Mountain Road will continue site by site, and we anticipate this work will take up to 12 months to complete.

Opanuku Road, Henderson Valley

22 March 2024

On Opanuku Road there are 10 sites where damage has been caused by 2023 weather events.

• 6 of these will be looked after by the maintenance team as they relate to scoured pavement and drainage
• 2 are over slips that we are currently reviewing the plans for, these are most likely to be tidied up and hydroseed but no major works expected
• 2 are under slips that have been made safe, are being monitored and on the list to be repaired. They are in the 6-12 month bracket from now, as they are lower on the priority list than some of the higher volume collector roads.

As these sites get closer to delivery we will be able to provide an update on the timing of the works.

Otitori Bay Road, Titirangi

30 April 2024

We started works on the second slip at 40 Otitori Bay Road on 11 April 2024.  We are building a 20m long retaining wall at this location. The team will be drilling to install the 14m long piles for the retaining wall.

Before works started we had some ecologists on site to install bat monitoring sensors to ensure that the vegetation clearance work did not affect any of the resident bats. NZ Ecology have also been monitoring lizards and birds.

During works a full road closure will be in place 24 hrs a day, seven days a week. Works will take place between 7am and 7pm. We anticipate works will take eight weeks to complete.

Pedestrian access will be available up until 8.40am in the morning and after 3.30pm, to allow school students and other pedestrians through.

Vehicles will not have access through.

Paturoa Road, Titirangi

The road is closed around number 15, and work is continuing on the design of the repair for this road.  Below is some information about the damage at this site.

13-15 Paturoa Road

• The underslip has occurred below an existing timber pole retaining wall, which appears to still be in place, but is undermined
• An Overland flow path is running through this location which will have to be considered during the design phase along with existing storm water network which needs to be reviewed
• Temporary traffic management/ weight limits are in place until repairs are completed
• An underslip extends from the driveway of 12 Paturoa Road for 23 m to the north-east.

Piha Road

Works on the slip site at 73 Piha Road were completed December 2023.

Rayner Road, Piha

30 April 2024

47- 49 Rayner Road, Piha

Flexiposts have been installed to keep vehicles away from the slip side of the road. The weight restriction is lifted. Our contractor is continuing to monitor this section of the road.

11 December 2023

The retaining works to repair the slip damage at the location of 27 Rayner Road is now complete. The road is open.

Scenic Drive, North Swanson

30 April 2024

Watercare are just finishing off the last of their works, and we anticipate they will complete this in the coming week.

AT is working with our contractor on the final designs for the repair work on this section of the road. Once we are ready to start works, we will notify the community, we anticipate works will start mid-May. There are no plans to fully close the road during these works.

15 March 2024

Watercare are currently working on this site, and their works will take 5-6 weeks, weather dependent. Once this work is complete, Fulton Hogan, on behalf of AT will complete the repairs to the road.  Both the work from Watercare, and the road repairs will be done under traffic management. There are no plans to close the road during these works.

9 October 2023 Summary of the decision for Scenic Drive North, Swanson 

Auckland Transport has been investigating options for repair and remediation to the Scenic Drive North site. 

All options have been considered and evaluated and reported to Auckland Transport.

Reporting on these options was available at the end of September, which has now been reviewed by Auckland Transport, its’ advisors, and appointed Contractor. Following consideration of the options, the group has selected minor local interventions and monitoring as the best option. 

The local interventions and monitoring will include the following:
• Localised repair of the road surface only.
• Sealing of roadside drains, and investigation of improved road drainage.
• An extended period of monitoring, which will be reviewed annually.

A full description of the summary note of this update is available here

Scenic Drive, between Shaw Road and West Coast Road (Various sites)

25 March 2024

This stretch of Scenic Drive has a number of slip sites, which we are working on, their location is indicated by the distance from Titirangi End of Scenic Drive. 

Site 1 - 6.58km from the start of Scenic Drive

An option report - with 3 options for the repair is under review currently, to decide on the repair for this site.

Site 2 - 6.73km from the start of Scenic Drive

Draft design is complete - is progressing through the approval processes. We anticipate this site to start construction in the second quarter of 2024.

Site 3 - 6.84km from start of Scenic Drive

Repair works were completed in March with the crew putting the finishing touches on the job including the sight rail and resurfacing work.

Scenic Drive, Near Arataki

30 April 2024

The excavation of this site took longer than expected, with poor ground conditions. A lot of the material had to be removed from site, as its condition meant we were unable to reuse it.

We have been working on the storm water drainage system to install a system that helps remove the sediment from the water as it travels offsite.

Now we are working on drilling and installing the steel piles which will form the retaining wall to support the road.

12 March 2024

As expected, this site has been challenging with poor ground conditions, and we have had some additional rain since we began works.

A revised design has been finalised and we are currently building the working platform ahead from which we will be able to work from to install the piles (or long beams.) We are also upgrading the stormwater culverts.

31 January 2024

We have started works on the repair at this site. The road will remain closed whilst works are completed. 

The road is closed at this section and there is no through access. The access to Arataki Visitors Centre is only open from the Titirangi End.

Please note there were also 10 slip sites between this site on Scenic Drive and Woodlands Park Road. These are also being worked on. 7 of these sites are completed with 3 more in the design phase. 

 Scenic Drive, Waiatarua (Elevation Site)

12 March 2024

Road repair works have been completed at this site, and the road is open two way. We are pleased to have this important connection open for the community. We will complete a final road reseal when other works in this area are completed.

7 March 2024

Repairs will start tomorrow 8 March 2024, we will be completing repairs to the road, and sealing cracks in the surface of the ground outside of the carriage way. We will also be completing works to the storm water drainage.

Works will even out the road and make it smooth and level to drive on. We anticipate that once this stage of work is complete the road will be re-opened two-way.

What happens next?

Final design plans are progressing for this site, this is a drainage solution. A series of fan drains will be installed to reduce pore pressures from within the slip. Residents that have properties within the slip site have been contacted and we are discussing the fan drain option with them. This final stage of repair works will include work across private properties, so this is an important element of the planning process. 

Scenic Drive, Titirangi 

February 2024

There are two large slips on Scenic Drive in Titirangi where the footpath and edge of the road has slipped away. Part of the road is coned off and traffic has been restricted to one lane by temporary traffic lights.

We started work  on 27 February 2024. The work will take place between the roundabout at Titirangi and Woodlands Park Road and it will take 3-4 months to complete (weather dependent). Work will take place during the day, 7am to 7pm.

During the works, this section of the road will be closed 24/7.

Pedestrian and cycle access will be made available beside the work site on Scenic Drive, and also through Kohu Road.

The following bus routes are affected by the closure:

To fix and secure the road we need to build large retaining walls at each of the slip sites. To do this we need to use heavy equipment which will need to sit on the remaining section of the road. This is a major repair, and is required to prevent further slips in this location.

The works will include:

• Clearing the slip material
• Cutting into the existing road to create a working platform for our heavy equipment
• Drilling large holes into the ground in which the steel columns will be placed
• Placing of concrete panels which will retain the road and footpath
• Backfill behind the wall and reinstate the drainage, footpath and road pavement

The detour route:

During works this section of Scenic Drive will be closed. The detour route will be along Woodlands Park Road and Huia Roads, as shown in this picture. We understand the inconvenience that this will cause, and ask drivers to plan ahead and allow extra time. 

Pedestrian and cycle access will be made available beside the work site on Scenic Drive, and also through Kohu Road.

Seaview Road

Works are complete and the road is open.

Simpson Road

113 Simpson Road - The repair is in the design phase.

• A road subsidence has occurred and extended approximately 107m in total in length with 77m of significantly affected carriageway – Failing Retaining wall is located along the edge of the road on the downslope side.
• Cracks have been sealed and temporary traffic management in place until repairs are completed.

We will continue to monitor the site until permanent repairs start

Takahe Road, Titirangi

30 April 2024

We anticipate works to repair the slip on Takahe Road will begin in May.

To prepare for the works we have to extend the length of the one lane closure, and the access through this will be by temporary traffic lights. We will be in contact with the community when the start date is finalised. 

Where and when

Te Henga Road

24 November 2023

There is a slip on the side of the road. The road is open with one lane, please use give way rules.

The design of this repair needs to take into consideration the proximity of the power lines. We are working with Vector on this, and will update the community when repair work will start.

Titirangi Beach Road

30 April 2024

Titirangi Beach Road repairs have been completed. Many thanks to the community for your patience through the works.

Wairere Road

 13 September 2023

We have reviewed the geotechnical testing that was completed at this site and are working on a repair that we anticipate will start in May 2024.

Open – under reduced speed of 30km/h. Buses & heavy vehicles can use but must travel at a slow speed.

No public access to Lake Wainamu, sand dunes, Bethells Beach & Te Henga walkways.

Waitākere Road Bridge - Underpass closed

Underpass closed at the Intersection of Waitākere Road & Bethells Road.

Extra crossing signs and Hit sticks have been installed on the approach to Bethells Road from Waitakere Road (Township end) for visibility and to improve safety.

The speed limit has been lowered from 1 April 2023 to 60km/hr near the intersection (between 190m north of Bethells Road and 220m south of Township Road).

Pictures of the initial extra signs and hit sticks that were installed in February are below.

Woodlands Park Road, Waima

1 March 2024

At the end of 2023 we were completing further geo tech testing in the slips. We are currently in the design phase of the repair for Woodland Park Road.

As this road is currently a part of the detour route for the works on Scenic Drive, the repair work for Woodlands Park Road will be scheduled once Scenic Drive, Titirangi is completed.

13 September 2023

In late August we removed polystyrene cover to undertake further soil testing and evaluate the extent of the slip.

Yelash Road, Massey

4 August 2023

Multiple underslips have occurred along Yelash Road near property number 13. The stream and a couple of culverts will need to be worked into the design.

We are working on a design for this road, and we are communicating with the property owner.
