Te Atatu roundabout rebuild continues
From Sunday 22 January 2017, contractors will be continue work begun in November to level out the road surfaces where Te Atatu, Edmonton, Lyndhurst and Flanshaw Roads approach each other and meet at the roundabout.
Most work will be done at night to avoid disruption to daytime traffic. The roundabout will have a change in operation and temporary road layouts, detours, and traffic management will be in place.
Between 7.30pm and 5am, the intersections between Te Atatu Road and Lyndhurst and Flanshaw Roads will be closed, as will the southern entrance of Te Atatu Road to the roundabout. Detours will be in place.
The connection between Edmonton Road and Te Atatu Road north of the roundabout will remain open at all times under Stop/Go control.
Noise will be kept to a minimum but AT and Higgins Contractors will work with affected residents before and during the works.
Work is expected to be completed by 2 February 2017 (weather permitting).

Te Atatu roundabout rebuild night works
Contractors are beginning works to level out the road surfaces where Te Atatu, Edmonton, Lyndhurst and Flanshaw Roads approach each other and meet at the roundabout.
Most work will be done at night (between 8pm and 6am) to avoid disruption to daytime traffic flows.
Weather permitting, work is expected to be completed on or before the night of Monday 12 December.
Work at the intersection of Vera Road and Te Atatu Road has begun. The work includes drainage installation and service crossings on Te Atatu Road. Drainage installation on Vera Road will start on 21 August.
The intersection of Lyndhurst Road with Te Atatu Road will be closed until 21 August (approximately) while a second stormwater treatment station is installed.
Other recent progress:
- Edmonton Rd pavement works have started (pictured). Works will be on one side of the road at a time, with some work being done at night.
- Streetlight installation is 35% complete.
- Service relocations, drainage, retaining walls, and property works are continuing.
Lane closure from 13 June
From 13 June, Te Atatu Road will have only 1 northbound lane between the Edmonton Road roundabout and the motorway. This is to give workers safe work areas as they continue to move underground services (power, phone, and gas)
Improved flow from Te Atatu Road onto the motorway, via the newly completed motorway interchange, will help keep traffic moving towards the north and city, although delays may be experienced.
Two southbound lanes must be kept open to minimise tailbacks onto the motorway by traffic heading south in the evening peak. This means that the closed lane must be on the northern side even for works in the eastern berm.
It is not possible to have 2 northbound lanes in the morning and then switch to 2 southbound lanes in the evening. Traffic signals are hard-wired to control the different traffic flows north and
Work programmes for the week starting Monday, 30 May
- Te Atatu Road (eastern side) north from Lyndhurst Road - installation of drainage.
- Edmonton Road (northern side) between School Road and the roundabout - installation of drainage.
- Between Lyndhurst Road and Wakeling Road:
- Construction of the common services trench.
- Continue relocating the gas line.
Works for week commencing Monday, May 9
- Begin drainage work along Te Atatu Road at Lyndhurst Road.
- Continue installing common service trench on
westside of Te Atatu Road outside Countdown.
- Continue installing common service trench and testing / commissioning of water main on Te Atatu Road between Lyndhurst Road and Jaemont Avenue (south).
- Continue constructing retaining wall on Te Atatu Road between Jaemont (north) and Covil Avenues.
A common service trench creates one single conduit for all underground services instead of digging separate trenches for each (the trench is big enough to allow the appropriate clearances between each service).
Common trenches are a time- and cost-effective way to install services and also mean that services can be easily located for any future roadworks.
Works this week
- Continue drainage and water main works on Te Atatu Road between Lyndhurst Road and Jaemont Avenue.
- Begin site clearance and service trench digging on
westside of Te Atatu Road south of Edmonton Road (opposite Countdown).
- Begin drainage work at Lyndhurst Road.
A reduction in road lanes on Te Atatu Road this year is now only for part of the northbound lane - from the Edmonton Road roundabout to Vera Road - compared with the
Higgins Contractors closed a northbound lane to give themselves a safe working space to move underground services (power, water and phone) closer to new property
Higgins has now completed re-mapping the services and with a clear picture of what is under the surface, it is only necessary to partly close the northbound lane.
On Wednesday 4 and Thursday 5 May, night works will be carried out in Vera Road outside the pharmacy, weather permitting.
This work involves open trenching across the rear exit driveway from Amcal All Seasons for the installation and connection of a storm water pipe.
The hours of work are between 12 midnight and 5am on both days.
Night works will continue on Jaemont Avenue on Wednesday 4 May, from 8pm to 5am, and Thursday 5 May, from 8pm to 11pm.
Exit from Jaemont Ave to Te Atatu Road will be closed from 7pm until work ceases on both nights and will require a detour. The entrance to Jaemont Ave from Te Atatu Road will remain open.
Only 3 lanes are operating in Te Atatu Road for the duration of the
- Move underground services (power, water, gas phone, etc) in the berm, Higgins Contractors need to close the adjacent road lane for workers and vehicles to work safely. In some places, it is necessary to trench the road as well.
- Closing a north-bound lane causes less disruption than would
closinga south-boundlane, because:
- The speed of traffic
north-boundat peak times,is governed by 3 factors: the volume of traffic, vehicles merging from 2 lanes on the motorway on-ramp and vehicles stopping for ramp signals. This impacts all traffic queued in Te Atatu Road, in both lanes.
Because traffic speed is governed at the motorway and this won’t change, traffic speed through the work site remains much the same as always. The principal impact comes from the fact that by being in one lane, the traffic queue is longer.
- Having 1 south-bound lane would mean afternoon traffic would create a longer queue with greater motorway tailbacks. This would impact a much wider part of the roading network and is not acceptable.
- The speed of traffic
- It’s not possible to open 2 lanes
north-boundeach morning or to do “tidal flow” – 2 north-boundin the morning and 2 south in the afternoon. This is because it is highly unlikely that the closed lane will be in a fit state to open each day.
- Changing lanes to operate "tidal flow" would take time out of each day and add months to the project.
- It would not be possible to provide safe right-turn bays.
- A second lane closed by safety vehicles would occur during the cut-over period.
- Dangers may occur for workers and road users alike.
- Tidal flow" would not improve travel times.
- Underground services are being shifted in the eastern berm at present (nearest the city). This means
- the near-side south-bound-lane is closed.
- The next
south-boundlane remains south-bound.
- The next lane converts from north–bound to south-bound.
- The fourth lane remains north-bound.
- Because this is a permanent arrangement, traffic sensing equipment (induction loops) that helps control traffic lights phasing, has been re-positioned to the 2 south, 1 north layout. Shifting traffic back and forward for a tidal flow would essentially mean the loops are in the wrong position for one set up. This would affect the operation of the loops currently set up for the right turns into Jaemont Ave, Covil Ave and Vera Road. The arrangement cannot be adjusted daily to reinstate the north-bound lane or to accommodate tidal flow.
Businesses are open as usual
All Te Atatu business are open as usual and AT/Higgins are keeping driveways to businesses open 24/7.
Despite the roadworks, shops, restaurants, clinics and other businesses are still easily accessible. With the summer and school holidays, traffic should become very light.
Work began on 10 August 2015. The initial phase involves relocating underground services (power, water, stormwater and gas), relocating property front boundaries and other preparatory works (also called enabling works).
This phase also includes temporarily reconfiguring road markings in both Edmonton Road and Te Atatu Road. This includes removing flush medians to enable the area to be used by traffic while contractors are working in the existing traffic lanes. The roundabout has been reduced in size.

Cyclists should take alternative routes
Alternative cycle routes around Te Atatu Road and Edmonton
Preparatory work is also being done by owners to reconstruct the shops at the intersection of Edmonton, Flanshaw and Te Atatu Roads. This is a private project and not part of AT’s upgrade project.
Initial work on Te Atatu Road will be in the
- establishing new front boundaries for properties from which land has been acquired for road widening.
- moving underground services (phone, power, gas etc.).
- realigning footpaths.
The first stage of work will be in Edmonton Road between School Rd and Te Atatu Rd and a 30km/h speed restriction will be in place. Motorists are advised to expect delays at peak times.
Subsequent stages will continue this work the full length of Te Atatu Road, between Wakeling Ave and Bridge Rd.
Higgins will prioritise removing the Te Atatu roundabout and replacing it with a smaller one, which will operate until traffic signals are installed.
Construction begins on 4 August 2015.
Higgins Contractors have been appointed to undertake the Te Atatu Road corridor improvement works.
Work in the first week will involve measuring and marking for phase 1 of works, which will be on the berms. This stage will include
The road will be kept open during the work, but one lane may have to be narrowed to allow work teams to operate safely. Speed restrictions will apply in the area.
Public open day
A public open day will be held on Sunday 26 July, from 1pm to 5pm, at the Te Atatu South Community Centre, 247 Edmonton Road.
Auckland Transport and Higgins Contractors will explain the detail of the project and the work timetable.
NZTA will also explain their project to upgrade the Te Atatu Motorway Interchange and the Causeway and how this connects to Te Atatu Road.
Tenders from contractors wanting to carry out the Te Atatu corridor upgrade have been received and are being evaluated.
The successful contractor will be announced soon and they will then work with Auckland Transport to define the stages in which work will be carried out.
The first stage of the $30 million Te Atatu Road Corridor is underway between the motorway and Wakeling Avenue - a development which will help traffic to flow better on Te Atatu Road and into and out of, surrounding streets.
- The roundabout at the intersection of Te Atatu, Edmonton and Flanshaw Roads is to be replaced by traffic signals. These will be synchronised with other traffic lights along this route, to ensure that traffic benefits from better and fairer control.
- Because the roundabout has to go, Auckland Council removed the sculpture (which it owns). Several months earlier, Vector Communications moved
itsunderground services on Edmonton Road.
- Right-turns from Te Atatu Road into Flanshaw Road will be prohibited but alternative routes will be available to affected motorists.
- Other features include bus priority measures, widened intersections with dedicated lanes for left and right turning and straight-ahead traffic, on-road cycle lanes and shared cycle/walking paths.
- Meanwhile, a painted flush median between Wakeling and the motorway will enable turning vehicles to get out of the traffic stream - helping to improve overall traffic flow and giving a
clearwayfor emergency vehicles.
Edmonton Road shops
The first phase of the development included the demolition of the shops on the intersection of Edmonton and Flanshaw Roads to give Auckland Transport (AT) room to widen Edmonton Road to three lanes at this point to give better traffic flow into Te Atatu Road.
With AT having made room for the road widening, a new block of shops will now be built beside the intersection restoring the service and convenience residents have always enjoyed.
Getting to this point was made possible by the Wong family who owned the original block of shops and who will build the new block.
Auckland Transport only required a piece of the Wong’s land to widen the intersection, but it also needed to demolish part of the block.
As we couldn’t just demolish some of the shops, AT bought the whole site and demolished the whole building. This enables us to subdivide the property, keep the “slice” of land that we need and sell the rest back to the Wong family. They will aggregate this with the next door property that they own and build a modern, architecturally-designed, mixed-use block as illustrated above. Mixed-use allows the block to be used for any mix of apartments, shops and other businesses.
Contractors are now being asked to submit tenders to undertake the corridor works. The appointed contractor will not undertake all the works all at once, but in stages thus limiting inconvenience to road users to different places at different times, rather than along the whole length of the road at all times.
Once appointed, the contractor will identify the various stages they will construct at any one time, the sequence in which the stages will be upgraded, and the timing for each stage.
This information will be provided to affected residents specifically by personal communications and; to residents and road users generally by way of articles in news media, newsletters, advertising, and roadside signage.
Works will commence in July 2015 and take about 2 years.
Construction of the new shops is a separate exercise carried out by the landowners and is expected during 2015.
