Frequently Asked Questions: Wynyard Crossing Bridge

Why is the Wynyard Crossing Bridge closed?

The bridge is closed to undergo extensive repairs and maintenance, including a full overhaul of mechanical and electrical systems, structural repairs, and the application of protective coatings. These works are essential to ensure the long-term durability and safety of the bridge.

When did the maintenance work start?

The bridge was closed in March 2024, marking the beginning of this major maintenance project.

How long will the bridge remain closed?

We anticipate it will be fully reinstated and back in service by December 2024.

What specific work is being done?

The work includes removing the bridge spans and engine rooms for offsite repairs, repairing or replacing the mechanical and electrical components like winches and cables, sandblasting steel elements, and applying new protective coatings. Rewiring and refitting the bridge systems will follow once the parts are reinstalled.

Why can’t the bridge be repaired on-site?

Many of the critical components, including the steel spans and engine rooms, require specialised offsite repairs. Working in a controlled environment allows us to complete the work faster and more efficiently, ensuring the highest standards of safety and quality. However, there are parts of the bridge that are being worked on in-situ, like the piles and crossing braces. 

Will the bridge look any different after the maintenance?

Visually, the bridge will look very similar, but it will have significantly upgraded internal systems, new protective coatings, and new and improved mechanical components. These updates will ensure its long-term functionality and reliability.

What are the biggest challenges of the project?

One of the key challenges is that many parts of the bridge are no longer manufactured, meaning custom components must be designed, commissioned, or adapted. The integration of the mechanical, electrical, and structural systems is also a complex task requiring precision and coordination. On top of that, a busy marine environment presents a lot of challenges.

How much will this renewal work cost?

The Te Wero Wynyard Crossing Bridge is on track to reopen in December 2024. As we enter the final stages of this large, complex project, the overall project budget for the repairs and restoration has been revised to a final cost of approximately $10.6m. This includes contingency funding should there be unexpected costs as the project completes.

What was the original budget?

In July, we provided a budget of $7.7m to our board for the project, including structural remediation and the repair or replacement of mechanical and electrical components. Now that the three programmes have begun to align (mechanical, electrical and structural) and the full extent of the works required is clear, this has been revised to a final cost of approximately $10.6m. The board approved this additional funding in September 2024.

Why did the budget increase?

Work completed since late August, removing structural elements and enabling the project team to thoroughly inspect the internal workings has enabled a clear picture of the extent of reparation needed, some of which was worse than previously understood. As a result, some project costs have increased. This will not impact the bridge reopening in December 2024.

Why have you not just replaced the bridge?

It was always intended that the bridge, a temporary installation for the 2011 Rugby World Cup, would be replaced. However, funding requests over the years have not been successful due to other strategic council priorities on the waterfront taking precedence. The investment being made now will allow the current bridge to reliably and safely operate for a further 15+ years.

How can the public stay informed about the project’s progress?

Subscribe to our monthly newsletter, where we provide detailed updates on the project. You can also visit our bridge website for real-time updates and key information.

Is there an alternative route across the water to access the Wynyard Quarter while the bridge is closed?

Yes, during the closure, a free ferry service is available for commuters and visitors, running 7 days a week from 7 AM. The ferry provides quick and reliable access to the Wynyard Quarter. Simply follow the signs to find the ferry.

There is also a detour around Viaduct Harbour and a number of buses that can get you there.
