Dairy Flat Highway safety improvements Dairy Flat Highway safety improvements

A number of safety improvements are proposed for the Dairy Flat Highway as part of Auckland Transport’s road safety network review.

Public feedback closed Sunday 1 July 2018.


Project status: Investigation
Project zone: North


Project overview

As part of our road safety network review, we have identified a stretch of road on the Dairy Flat Highway that has a number of safety issues.

The Dairy Flat Highway is a former NZ Transport Agency (NZTA) State Highway, and is ranked within the top one per cent of roads recommend by NZTA for investment due to the high-risk intersections and roadside hazards.

The scope of work we are looking at is from Pine Valley Road to Stevensons Crescent. Across this stretch there are a number of safety improvements being proposed.

Benefits

  • Safer journeys for people driving around Dairy Flat Highway.
  • Potential for new safety measures such as flexible road safety barriers, wider centrelines, slow vehicle lanes, rumble strips and intersection upgrades.
  • Safe speeds, including lower speed limits.
  • Reducing the speed limit and traffic calming will create a more appropriate village feel, especially around the Kahikatea Road intersection.

Timeline

  • June-July 2018 – stakeholder engagement on Dairy Flat Highway safety improvements.
  • November 2018 – public information on the Dairy Flat Highway safety improvements
  • 2018/19 – construction starts on safety improvements

Project details

The Dairy Flat Highway sits within the top one per cent of roads recommended by NZTA for investment because of the speeds, dangerous intersections and roadside hazards.

The former State Highway has also had a number fatalities and serious crashes.

Between 2012-2018 there have been 7 deaths and 29 serious injuries on the Dairy Flat Highway.

The North Shore’s population is expected to grow by 17 per cent over the next 10 years, with 6,000 more homes to be built around Silverdale and Dairy Flat. With vehicle numbers set to increase over the next decade, better and safer roads are required.

Making the road safer

There are a number ways AT can improve the safety on the highway, some of these possibilities include:

  • Flexible road safety barriers, such as wire ropes, to reduce the risk of head-on crashes. Barriers reduce the number of people killed on roads by 90 per cent.
  • Rumble strips on the road markings to remind drivers they are on the centre line.
  • Wide centrelines are a simple way to steer drivers away from each other.
  • More signage and road markings.
  • Safe speeds, including lower speed limits and traffic calming.
  • Slow vehicle lanes, these allow for slower vehicles to pull over.
  • Intersection upgrades, such as roundabouts and right turn bays.

Public consultation


We asked for feedback from property owners, residents and the general public . We wanted to find out:

  • Did you have any concerns around safety on the Dairy Flat Highway, in particular from Pine Valley Road to Stevensons Crescent?
  • What type of safety improvements would you like to see put in place, from Pine Valley Road to Stevensons Crescent?

Public feedback closed Sunday 1 July 2018.

After feedback closes

We will prepare a report on the feedback which we will publish on the project webpage. The feedback you provide will help with the next stage in formulating proposals to make Dairy Flat Highway safer. If you provide your contact details when you give us feedback, we will notify you when the report is available.
