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.

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).
