No. 4 Road bridge
Kia ora, welcome to the No.4 Road bridge project page. Here, you’ll find everything you need to know about the project, including latest updates, concept designs, and a timeline of upcoming steps. Check out the information on the right-hand side of this page for all this and more.
About the project
A new bridge is being built to replace the No.4 Road bridge that was washed away during an extreme storm event in January 2023.
The 30m-long, single-lane bridge across the Te Raparaoa-ā-hoe stream will replace the temporary Bailey bridge - a portable, pre-fabricated truss bridge hired from New Zealand Transport Authority Waka Kotahi (NZTA) - that was put in place following the storm.
The new bridge is being built downstream of the Bailey bridge, which will remain in place until the new bridge is completed.
The bridge is expected to be operational by early March 2025 and the project fully completed by the end of May 2025.
* For those wanting to cool off in the river, our contractors have created access to a swimming spot downstream of the Bailey bridge. We know people like to jump into the river from the Bailey bridge, but this isn't safe while works are taking place. So, please swim downstream for the time being.
What’s happening now? (4 April)
We are now looking at Tuesday 8 April for the concrete pour on the bridge deck and abutments.
No. 5 Road will be closed from 4am to 1pm while we carry out this work, and No. 4 Road will be under Stop/Go traffic lights. No. 5 Road residents will need to use the alternative access through to Manoeka during this time.
31 March
Tomorrow's concrete pour (Tuesday 1 April) has been delayed and will now be completed later in the week.
Unfortunately, we have been unable to complete the set-up for tomorrow and, with the weather looking average later in the week, we will make the call on the pour once we can ensure we have good weather.
We will let you know as soon as we have a new date for the pour.
26 March 2025
The planned concrete pour for Thursday 27 March has been delayed and will now be done next week. This means No. 5 Road will be closed on Tuesday 1 April between 3.30am and 1pm, while we pour the deck and abutments on the new bridge.
No. 4 Road will remain open under Stop/Go traffic lights during the pour - for all traffic, including heavy vehicles.
No. 5 Road residents will need to use the alternative access through to Manoeka during this time.
If the pour is delayed by wet weather, the backup day is Wednesday 2 April.
23 March 2025
Another productive week - we completed the grouting pads under the beams, installed reinforcing on the abutments and deck, installed formwork on the deck and northern abutment, and removed trees on the northern embankment.
21 March 2025
On Thursday 27 March we will be doing the concrete pour for the bridge deck and abutments.
During this time, we will need to close No. 5 Road (5.30am - 1pm), so we can set up the concrete pump on the southern side of the bridge.
There will also be a concrete pump set up on the northern side, but this will be off-road to allow No. 4 Road to stay open, under Stop/Go traffic lights.
Access for all traffic, including heavy vehicles using No. 4 Road, will remain open, but there may be some minor delays while concrete trucks are backing up to the pumps.
No. 5 Road residents will need to use alternative access through Manoeka Road at this time.
If the pour is delayed by wet weather, our back-up day is Friday 28 March.
