Feedback open from 11 July-19 August 2022

Thank you to everyone who gave their feedback on the long-term transport connections for North Auckland. Feedback has now closed.

Next steps

We will review all feedback and consider how we can incorporate this into any changes to our preferred options.

The next step is to complete more detailed investigations for all preferred options. During 2022, environmental and technical assessments will continue along with engagement with Manawhenua, partners, local property owners, developers and key community stakeholders. This will help us make decisions to confirm the preferred options.

We expect to complete the North Auckland Detailed Business Case process mid-2023 for consideration by the Auckland Transport and Waka Kotahi Boards, followed by the lodgement of the Notice of Requirement.

Our planning work will integrate with Auckland Council’s land use plans including the draft Spatial Land Use Strategy for Dairy Flat and Silverdale and the Silverdale West Dairy Flat Industrial Area Structure Plan to support future growth for these areas. It will also need to consider how they will integrate with other long-term projects such as Penlink, the new rapid transit corridor, the new SH1 cycleway and upgrades to local roads.

The majority of these SH1 improvement projects are yet to be funded for delivery. It is anticipated they will be considered for funding in line with the long-term timeframes for the rezoning and release of land by Auckland Council over the next 10-30 years.


Future improvements for State Highway 1

Over the next 20 to 30 years urban growth will mean that North Auckland will need a range of new and improved transport choices to help new communities move around.

We’re planning now because it’s important to protect the land needed to build new transport connections over the next two to three decades as urban development occurs.

Future improvements to State Highway 1 (SH1) between Albany and Silverdale are proposed to help support future urban growth in North Auckland. A range of future upgrades will improve safety, access and capacity for public transport, walking and cycling, private vehicles and freight.

We’re proposing a range of long-term improvements:

  • A new walking and cycling path along SH1 to help future communities move around by active, low-carbon travel options, and access public transport services.
  • Interim bus lanes on SH1 from Albany to Silverdale to increase efficiency of the public transport network (before the rapid transit corridor from Albany to Milldale via Dairy Flat is in place).
  • Upgrades to the Redvale interchange (currently being constructed as part of the Penlink project) to help provide connections to and from SH1.
  • A new interchange at Wilks Road will improve access to the future Silverdale West industrial area.
  • Upgrades to the Silverdale interchange will improve safety, accommodate new walking and cycling connections and improve traffic flow from east to west.

These future improvements for SH1 are yet to be prioritised for funding with construction expected within the next 20 to 30 years.

Why do we need these improvements?

North Auckland is growing fast. By 2050 it’s expected there will be at least 41,000 new homes, 22,000 jobs and 110,000 new residents. Most of this future growth will occur in Silverdale, Dairy Flat, Wainui and Ōrewa.

Current and future communities need new and improved transport infrastructure to make travel safer, easier and more sustainable. We’re planning ahead to ensure that essential transport infrastructure can take place alongside growth and development in the future.

SH1 plays an important role in the north and regionally, connecting freight and people from the city centre to the northern areas of Auckland and beyond. Upgrades along this key section of SH1 will improve safety, increase access to key destinations, provide more sustainable travel choices, and greater capacity to support planned growth in Silverdale, Wainui, Dairy Flat, Ōrewa and the wider Hibiscus Coast over the next three decades.

Benefits:

  • Upgrades at interchanges to improve safety and connections.
  • New or improved crossings over SH1.
  • Extra connections to access key destinations.
  • Additional public transport services to improve access to the wider public transport network and encourage a shift to low-carbon travel alternatives.
  • Additional space on SH1 to respond to an increase in travel demand in the long term.

What are we proposing?

Future Urban Zone

In the future, SH1 will be widened to three lanes in each direction between Lonely Track Road and the Silverdale interchange. In the interim the additional lane will be used for public transport until the new Rapid Transit Corridor is constructed. In the long term, this additional lane could be used for public transport, high occupancy vehicles or freight.

We’re proposing to provide three lanes in each direction between Albany and Silverdale – we’re proposing to widen:

  • To the east side of SH1 from Lonely Track Road Bridge to near Awanohi Road.
  • On both sides of SH1 from near Awanohi Road to Bawden Road.
  • On both sides of SH1 from Bawden Road to Silverdale interchange.

There is no need to widen the section of the motorway between Albany (Oteha Valley Road) and Lonely Track Bridge on SH1 as there are already three lanes in each direction.

Features:

  • Improved safety between Albany and the Silverdale interchange.
  • Three lanes in each direction – to support increased transport demand, such as high occupancy vehicles and freight or for public transport.
  • Interim bus priority lanes will improve public transport reliability for the Northern Express.
  • Additional lanes will provide flexibility to respond to changes in travel demand and manage the movement of people, services and good more efficiently.

What could it look like?

The interim bus lanes will use the existing bus shoulder which will be widened. With this space being used as dedicated interim bus lanes, the motorway could look like this: (click on image to enlarge)

Cross section is indicative only

In the future, the new rapid transit corridor, new SH1 cycleway and additional lane will share the same corridor between Albany and Bawden Road (where the rapid transit corridor will divert into the Dairy Flat future urban area):

The Penlink project (currently being delivered by Waka Kotahi NZ Transport Agency) will provide a new two-lane transport link which will connect the Whangaparāoa Peninsula to State Highway 1. The project provides connection to SH1 with south facing ramps only (connection to and from the south). A future upgrade of this interchange is proposed to provide connections to and from the north. The upgraded Redvale interchange will work with Penlink to open up the area, improve connections to Dairy Flat and Silverdale, and support public transport and walking and cycling along these corridors.

In the future, a new interchange at Wilks Road with south facing ramps will provide access between the Silverdale West Dairy Flat future industrial area and SH1, including freight from future industrial land uses.

Features:

  • Safe, well-connected interchanges will be designed to accommodate walking and cycling, public transport and general traffic.
  • Direct connection to Penlink, opening up access to/from the Whangaparāoa Peninsula.
  • Improved access for Redvale, Dairy Flat and Silverdale.
  • Provide industrial traffic with a direct connection between the Silverdale West Dairy Flat future industrial area and SH1.

In the future, the existing Silverdale interchange will be upgraded to make the interchange safer and operate more efficiently.

We’re proposing an additional bridge to cater for more people wanting to travel through the interchange, a new walking and cycling connection to provide a safe crossing over SH1 from east to west, and safety improvements at intersections.

These future upgrades will support the growth of communities by providing better access and improving local connections and transport choices.

Features:

  • A separated walking and cycling path through the interchange from north to south as part of the SH1 Albany to Grand Drive cycleway
  • Safer intersections
  • New walking and cycling facilities will allow people travelling on foot or by bike to cross safely over SH1 from east to west (both directions).
  • A second westbound lane will improve traffic flow for east west movements through the interchange.
