State highway projects

Our role in managing New Zealand's state highways includes working with the government and partners throughout the country to identify and respond to opportunities to improve safety, capacity and efficiency on our roads. One of our key goals is to support economic growth and productivity throughout New Zealand. Together, we develop projects based on thorough analysis and, where appropriate, extensive consultation to ensure they can be implemented cost effectively while delivering immediate and long-term gains to road users and the economy as a whole.

Currently active projects are listed below. For completed state highway projects, view the completed projects section in the navigation.

Ngauranga to Petone cycleway..

Updated: 27 May 2015

The NZ Transport Agency is investigating options to deliver a safe and efficient route for cyclists between Ngauranga and Petone along State Highway 2. This project aims to "close the gap" of the existing cycleway along SH2, support existing cyclists and encourage more people to travel by bike between the Hutt Valley and Wellington.

The Transport Agency is working in partnership with Wellington City and Hutt City Councils on this project, to ensure that the cycleway effectively and efficiently connects with other cycling facilities at either end of the proposed highway facility.

The project is ranked number 5 in the Regional Land Transport Plan and referenced as the Wellington to Hutt Valley Cycleway/Walkway/Resilience project.
