Asquith Ave and New North Rd, Mt Albert - Intersection Upgrade Asquith Ave and New North Rd, Mt Albert - Intersection Upgrade

Consultation status: closed 21 February 2018

Proposal reference: RTV-130

Proposed intersection upgrades will include:

  • Relocation of the central traffic island on New North Road to a position slightly west, reducing exposure time for right-turning traffic from Asquith Avenue.
  • Realignment of traffic islands at the intersection and the installation of flexi-posts to prevent right turning movements from New North Road onto Asquith Avenue.
  • Installation of a speed table at the entrance to Asquith Avenue and a speed cushion on Asquith Avenue approaching the intersection.
  • Installation of a rubber cycle buffer along the cycle lane to give cyclists better protection.
  • Repainting of road markings and relocation of signage as indicated in the drawing.
  • Further lighting upgrades.

This intersection is identified as high-risk, with a number of documented collisions:

  1. Between motorists turning right out of Asquith Avenue and those heading eastbound on New North Road.
  2. Due to road users performing illegal right-turns from New North Road onto Asquith Avenue.

We expect that this proposal will considerably reduce safety risks to all road users by effectively reducing the amount of time that the traffic turning right out of Asquith Avenue is exposed to oncoming traffic, and by further dissuading road users from making illegal right-hand turns from New North Road onto Asquith Avenue.


The proposal received mixed feedback with some concerns raised by respondents. After reviewing this feedback and all other supporting evidence, the proposal will proceed to the next stage of detailed planning, where minor changes may be made in response to the feedback received.

Specific feedback

Traffic island configuration

  • Request to lower the height of the existing traffic island on New North Road and to extend it further east along the road. The height of the proposed traffic island cannot be lowered as it is of the standard height and serves to dissuade vehicles from turning right into Asquith Avenue from New North Road.
  • Enquiries into why the current traffic island on New North Road is not sufficient. With the current intersection layout, vehicles turning right out of Asquith Avenue are exposed to oncoming traffic for an extensive period time as they need to negotiate around the existing traffic island, which is located directly in their driving path. As explained in the consultation letter, this proposal aims to provide a more direct path from Asquith Avenue onto the flush median on New North Road, and also to further prevent drivers from performing prohibited right turns from New North Road onto Asquith Avenue.

Bicycle lane

  • Requests to remove the bicycle lane (a) into Asquith Avenue, and (b) along New North Road. We aim to make roads more user friendly by developing and maintaining facilities for all road users, including cyclists.
  • Concern over whether the “Swedish Speed Table” will be substantial enough to slow drivers as they approach the cycle lane and pedestrian crossing. The speed table will be constructed at a height of 100 mm to effectively slow vehicles as they approach and drive over it.

Left turn – New North Road to Asquith Avenue

  • Concerns that a more streamlined left turn from New North Road onto Asquith Avenue will allow drivers to speed through the intersection without indicating, causing a safety hazard. As there is a pedestrian crossing facility at the beginning of Asquith Avenue, speed management is crucial. The speed table will prevent drivers from turning left into Asquith Avenue at high speeds, improving pedestrian safety.
  • Requests to provide a refuge for vehicles to queue in the centre of New North Road after pulling out of Asquith Avenue. The purpose of the traffic island relocation on New North Road is to allow vehicles turning right out of Asquith Avenue a more direct route to the flush median, reducing the time they are exposed to oncoming traffic. The aim of this proposal is not to provide a queuing space for vehicles to merge into westbound traffic.

New North Road flush median

  • Suggestion to replace current flush median and expand with road markings that would delineate the zone as a vehicle refuge. New North Road is a major arterial road with large traffic volumes, often including heavy trucks. The proposal will expand the flush median to a width of 3 metres from 2.5 metres; however, we are unable to widen the flush median any further without compromising the capacity and efficiency of New North Road.

Flexi-posts/Rubber buffers

  • Concern that installation of flexi-posts could cause confusion to motorists. Operational issues have not been observed at other locations in Auckland where similar flexi-posts have been installed.
  • Request to remove flexi-posts from the proposal. The purpose of the flexi-posts is to further reinforce the “no right turn” into Asquith Avenue.
  • Suggestion that the flexi-posts are not overly sturdy and that a low maintenance alternative should be considered. We will examine all possible options when finalising the detailed design plan.
  • Concern regarding the visual appeal of the rubber cycle buffers to be installed. In order to maximise safety benefits to bicyclists, the rubber cycle buffers will need to be bright and reflective.
  • Requests to adjust the extent of the first set (west) of rubber cycle buffers. We will review the extent of the rubber cycle buffers in the detailed design phase; ultimately, we will decide to install the option that provides the most safety benefits to cyclists and other road users.

Traffic congestion

  • Concern that the proposal will have a “bottleneck” effect on Asquith Avenue, where drivers turning right onto New North Road would block drivers attempting to turn left. The proposal does not change the lane width for vehicles exiting Asquith Ave, therefore the proposal will have no impact on this movement.

Miscellaneous turns

  • Request to add left and right-turn lanes out of Asquith Avenue. Vehicles exiting Asquith Avenue do not appear to experience significant delays during peak traffic periods, so we are unable to justify road widening to accommodate another lane.
  • Suggestion to install a traffic camera to monitor and deter right-hand turns from New North Road onto Asquith Avenue. Currently, we only install traffic cameras at signalised intersections.
  • Request to prohibit turns into Asquith Avenue at peak times. Based on our observations, left-turns into Asquith Avenue do not cause major conflicts with other operations at the intersection.
  • Requests to prohibit right-hand turns out of Asquith Avenue onto New North Road. As outlined in the consultation letter, prohibiting right turns out of Asquith Avenue would only push demand to nearby intersections, which are less equipped to handle the traffic volume.
  • Request to either (a) widen or (b) adjust the angle of the lane out of Asquith Avenue onto New North Road so that vehicles turning right out of Asquith Avenue are not forced to turn at a 90 degree angle. There are a number of factors preventing us from widening this lane, the most important being pedestrian crossing distance. Widening the road at this point also means increasing the distance pedestrians would need to cover to get from the pedestrian refuge to the footpath, thereby putting them at greater risk.

Road markings

  • Requests to widen the flush median strip along New North Road. The proposal will widen the existing flush median from 2.5 metres to 3 metres.
  • Request to “curve” directional arrows to align with contours of New North Road. This will be considered during the detailed design phase.
  • Request to add a “left turn” arrow to the outer lane of New North Road heading eastbound. This is not typically recommended at intersections that are not signalised.

Speed calming

  • Request to install signage or a physical mechanism (i.e. rumble strips) warning drivers heading eastbound along New North Road to slow down. We will examine further methods of speed calming during the detailed design stage.
  • Concern that speed bumps do not fully dissuade drivers from speeding. The speed table proposed will be at the maximum height of 100 mm, which has demonstrated in other locations to effectively decrease the speed of vehicles.
  • Request to reduce the speed along New North Road to 40km/h. A significant reduction in the speed limit is likely to result in an increase in traffic congestion. 40 km/h speed limits are reserved for school zones only.

Driver error

  • Concern that vehicles turning out of Asquith Avenue often fail to stop. Based on our observations, this has not been identified as a common issue at this intersection. The speed cushion will help address the situation by forcing vehicles to slow on their approach.
  • Concerns that vehicles turning into Asquith Avenue frequently fail to indicate, causing confusion for other drivers and pedestrians. Unfortunately, this is a behavioural issue that cannot be directly addressed through engineering means. Installation of a speed table for the pedestrian crossing facility will force vehicles turning into Asquith Avenue to travel at a slower speed.
  • Concern that the tail ends of vehicles waiting in the median strip to merge with westbound traffic along New North Road often overhang the inner eastbound lane. The proposed flexi-posts that will be installed along the edge line of the flush median will better delineate the two opposing traffic flows.

Pedestrian facilities

  • Concern that the central traffic island on New North Road is often used as a pedestrian refuge. The proposed cycle buffers and the relocation of the central island on New North Road will discourage pedestrians from crossing at this point on the New North Road.
  • Request to install a sturdy barrier between the footpath and the road at this location to prevent injuries to pedestrians. Installation of a barrier at this location would not be a practical solution as it would likely impede access to driveways.

Taxpayer funds

  • Concern that the proposal is not far-reaching enough and is not a good use of taxpayer funds. As outlined in the consultation letter, several other options were considered during the investigation phase – such as signalisation and roundabout – and this option was chosen after careful evaluation. Although this option is the best solution for this intersection at this stage, we will continue to monitor after the implementation for future upgrades.


  • Suggestion that traffic along New North Road is intermittent and therefore, a roundabout could be constructed at this intersection. As outlined in the consultation letter, a roundabout is not a practical solution for this intersection because traffic volume is not balanced across all legs, thus likely to cause traffic to back up along Asquith Avenue. At present, the intersection is also not large enough to accommodate a roundabout.


  • Suggestions to signalise the intersection at peak times. Signalisation during peak hours would likely lead to confusion for drivers during off-peak hours, increasing the risk of accidents at those times.
  • Concern that lighting upgrades would adversely impact local residents. Standard lighting design has been prepared to ensure the road is sufficiently lit but with minimum light spill into the adjacent properties.
  • Concern that traffic lights along New North Road contribute to congestion and safety hazards. Suggestion to adjust the traffic light timers to allow more traffic through. Signal phasing will be reviewed during the detailed design stage to ensure compatibility with the proposed changes so that traffic along New North Road flows smoothly.

Road resurfacing

  • Requests to resurface the road with high traction surfacing to prevent vehicles from slipping and losing control in wet conditions. Adjustments to road surfacing will be examined during the detailed design stage.


  • Concern that the Asquith Avenue driveway to Mt. Albert Market will be adversely affected by the proposal, causing safety concerns for vehicles entering and exiting. A tracking model was undertaken for vehicles that currently access the driveway. The proposed design will not impact accessibility.

Miscellaneous requests

  • Request to relocate “no right turn” and “keep left” signs further east along New North Road. During the detail design stage the locations of the signs will be reviewed to ensure that they do not block driver visibility.
  • Request to install a traffic mirror on the New North Road central traffic island. We no longer install traffic mirrors as images are often misleading and inaccurate. The proposal allows for a complete view of traffic in both directions, so traffic mirrors would not be necessary.
  • Concerns that the camber of New North Road contribute to existing issues. In the detailed design stage, the road surface will be evaluated to insert additional friction grip treatment where appropriate.
  • Requests for additional works include:
    • Concerns that accidents occur when vehicles heading westbound along New North Road attempt to make right turns into businesses on the opposite side of the road.
    • Request to relocate bus stop No. 8231 further westward towards Mount Albert shops.

These requests are out of scope for this proposal which focuses on improvements to the Asquith Avenue/New North Road Intersection in Mt. Albert. If you would like your request to be considered by us for future development works, please provide feedback here.
