13 November update

Forecast high winds mean, for health and safety reasons, gantry installation won’t proceed as intitially planned tonight (Monday, 13 November.

At this stage, the gantry will be installed tomorrow night (Tuesday, 14 November) if weather conditions permit. An extra night will be needed to complete this work. An exact date for this is to be confirmed.

However, tonight’s planned highway closure will still proceed to allow resurfacing work to be done between Porirua and Tawa. Detours will be in place and drivers must expect travel delays.

There will be a full southbound lane closure tonight from 9 pm to 5.30 am.

It will affect State Highway 59 (between Mungavin Ave Interchange and Tawa) and State Highway 1 (between the Kenepuru Interchange and Tawa). The closure planned for Tuesday night will also proceed as planned.

Detour Information:

• SH59 southbound road users detour via SH59 at Mungavin offramp onto Titahi Bay Road, Kenepuru Drive, Main Road Tawa and Takapu Road back onto SH1 at the Tawa Interchange. 
• SH1 Transmission Gully Road users detour via SH1 Kenepuru offramp, onto Kenepuru Drive, Main Road Tawa and Takapu Road back onto SH1 at the Tawa Interchange.

6 November update

Full southbound lane closures are coming for State Highway 1 and State Highway 59 as the next steps are taken to improve how the highways are monitored and managed between Tawa and Porirua.

Contractors will install new speed management and traffic monitoring equipment and a new overhead gantry. It will hold new electronic signs that provide road users with real-time highway information.

The new infrastructure will help update drivers about what’s happening on their route. This will include crashes, congestion, and planned roadworks.

Because the new gantry is a large piece of infrastructure, a full southbound lane closure is needed, it means State Highway 59 (between Mungavin Ave Interchange and Tawa) and State Highway 1 (between the Kenepuru Interchange and Tawa) will be closed on Monday, 13 November and Tuesday, 14 November, from 9 pm to 5.30 am. 

Waka Kotahi appreciates a full highway closure is a big deal and does create disruption. However, every effort is being made to minimise the impact of this work as much as possible.Contractors will work at night when traffic volumes are much lighter. A full closure also allows the work to be completed much faster and is safer for contractors and road users.

Road users are encouraged to plan for the closure, as the detour will mean longer travel times.
