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: 12 December 2013

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 Inner City Bypass was upgraded in 2007. However, traffic can still become gridlocked at peak times, and as part of Tunnel to Tunnel improvement project ("T2T"), we can make further changes that will improve its performance (particularly once the Paterson to Tory Street Bridge is complete). To ensure we get the most from the new Bridge, T2T will include a range of upgrades along the Bypass.
