About the project

Well-planned transport investment delivers social, economic and environmental benefits. It helps communities thrive and safely connects people with jobs, schools, essential services and recreation.

We’ve completed the Western Ring Route to improve resilience for the movement of people and goods across the region, provided better access to public transport by extending the Northern Busway and supported walking and cycling with approximately 10km of shared paths to make it easy for people to get around.

  • Benefits
    • Provide a reliable journey time for people travelling through the area with direct SH1 and SH18 motorway to motorway connections.
    • Improve the resilience of the Auckland state highway network for people and goods travelling through the area and to the airport and wider regions.
    • Support people being able to leave their cars at home and travel around their local community on foot or by bike.
    • Separating vehicles on local journeys around their community from those travelling on the state highway to create a safer environment.
    • Make travel via public transport more appealing and reliable with the extension of the Northern Busway to Albany.
    • Create a welcoming and appealing community to live and travel through with an urban design created in partnership with mana whenua.
