I had a look at those numbers that Chris mentioned and I was surprised that two major arterial roads in Nelson have roughly between 19 and 21,000 vehicles a day yet a study found that there was absolutely no need whatsoever for a new road to be built or even road widening.

How many vehicles do you have to fit through two two lane roads per day in order for these sorts of people to say "yes, we need new infrastructure or modifications of existing infrastructure"?

The big difference is that the routes you're refering to in Nelson (Tahunanui Rd and Waimea Rd I presume) are urban routes as opposed to open road. 17-18,000 on an open road enviroment is quite different to the same volume on city roads and streets where the average speed is far lower (that is not to say the situation in Nelson is optimal).
I am familiar with the routes in Nelson and to be quite honest I couldn't think of an easily affordible or politically acceptable solution. You could add clearways or 4-lane the routes but considering the political culture in Nelson these options would be quickly rejected (considering a short 100m long clearway on Tahunanui Rd didn't even survive local nit picking). Even if you succeeded in widening Tahunanui Rd you still would never get the Rocks Rd section widened. That section will remain forever as it is.
Any major new arterial route would have to be built through the hills and this would require enormous amounts of tunnelling and bridging. Massively expensive.
So the only option left is to 4 lane Waimea Rd and Rutherford St. Good luck with that.

Nice pic showing Auckland's Southern Motorway just south of the CBD showing the Newmarket viaduct. NZ's busiest section of road (AADT 200,000) can be seen middle left running between the brushy area.

Is it just me or is that a new road with surface dressing? By that I mean road chippings sprinkled on wet tar. I'm surprised that has been done on a new road as I thought it was normal practice to do this when a surface starts to wear to get a few more years out of it.

Put it this way, I'd not like to drive on that for a while at highway speeds if there are a lot of loose chippings that are likely to cause stone chips in a car's paintwork or windscreen. I stretch of highway near to me was stone chipped last summer and I avoided it for a good few weeks for that reason.

Yes,chip-seal is used very widely in NZ.
In the case of new motorways I can think of a couple of curious examples where at opening the surface was chip-seal only to be then resurfaced shortly after with ashphalt. Seems to be a NZ thing to do it that way.
Whether this road will be resurfaced with ashphalt or remain as is, time will tell.

Hopefully they had the road cleared of loose chips when opened for general traffic.

This is indeed very normal in NZ to seal a road initially with chipseal, then later reseal it with asphalt.

A few points on this:

Asphalt is more expensive than chipseal (about 3 times the cost), though it's quieter to drive on and more durable than chipseal.

As a result, asphalt is usually only used in NZ on: 1) very busy roads such as motorways or urban arterial roads where its desirable to not have to reseal the road as often and 2) urban roads that receive a lot of traffic, especially a lot of stop start traffic by heavy vehicles as this can rip up chip seal roads easily... asphalt is more resistant and 3) short bits on rural highways particularly steep and/or winding roads where heavy vehicles are likely to rip up chip seal roads too easily and 4) where a busy road passes through residential areas which might create undue noise for residents.

As for why they chipseal a road first only to asphalt it later the reason they do this is that they lay the chipseal first, then let traffic use the road for a while, typically 3-6 months which helps the roadbed to settle. Any minor issues that arise due to subsidence, rutting, potholing etc can then be repaired. Once the roadbed is settled, then the final asphalt is laid.

If they lay the asphalt too soon, if there is movement in the road due to rutting and subsidence, then the asphalt may crack, which lets water in and causes potholes and allows heavy traffic to further rip up the surface.

In Alberta, Canada, for decades they have done similar technique... they pave with asphalt but only half thickness, and leave it that way for about 1-2 years, then pave with the 'final' asphalt layer. They say the initial cracks and such that form after freeze - thaw cycles and settling of the roadbed are sealed by the second pave later. Never see that elsewhere though...

NZ Transport Agency welcomes decision on Peka Peka to Otaki Expressway

The NZ Transport Agency is welcoming today's release of the Board of Inquiry's final decision to approve the regulatory and resource consents applications lodged by the Transport Agency for the SH1 Peka Peka to North Ōtaki Expressway Proposal.

Transport Agency Wellington State Highway Manager Rod James said the Board"s final decision has provided certainty for the project and for the people of the Kapiti Coast. The approval will now allow the Transport Agency to progress it to construction in 2016.

"We are now beginning to work on detailed designs for this stretch of the Expressway. This takes a considerable amount of time, and construction is scheduled to begin in mid-2016. We expect it will take about four years to build the road, and we are looking forward to working with stakeholder groups and local communities throughout the project."

Mr James says the adjoining MacKays to Peka Peka Expressway to the south is currently underway and is due to be completed in 2017.

The Peka Peka to North Ōtaki Expressway is an integral section of the State Highway 1 Wellington Northern Corridor which runs from Wellington Airport to Levin.

New Gates of Haast Bridge plans shelved

Three years of investigations have found that a new bridge cannot be engineered to withstand a major landslide or another significant event in the area, says the Transport Agency’s Canterbury/West Coast Highway Manager Colin Knaggs.

“The Transport Agency recognises the Gates of Haast is a unique site, not least because of the long detour (more than 930kms) and that any prolonged closure of the highway would have a significant impact on the region.
Full press release: http://www.nzta.govt.nz/about/media/...3216/news.html

A 930 kilometre detour, I don't think there are many locations in the world where a detour that long would exist.

The AADT on this bridge is 500 vehicles per day.

930km? Where exactly would one find this detour?

That's what the press release of the NZTA says.

According to Google Maps it's 1010 km from either end of the bridge.

Waikato Expressway

Funding approved for Huntly section of Waikato Expressway

The NZ Transport Agency Board has approved $458million in funding for the design and construction of the Huntly section of the Waikato Expressway.

The Waikato Expressway is one of the seven state highways, called the Roads of National Significance, identified by the Government as essential to New Zealand's economic prosperity.

Transport Agency Waikato Bay of Plenty regional director Harry Wilson said the funding approval meant construction of the 15.5km section would start in September 2015, allowing the Transport Agency to remain on track to complete the full length of the Waikato Expressway by 2019.

The Huntly section of the Waikato Expressway will start approximately 1.3km north of Fisher Road and will pass through the Taupiri Range, east of Huntly. Once complete, it will connect the Ohinewai section of the Waikato Expressway, in the north, to the Ngaruawahia section, which opened in late 2013.

Transmission Gully Motorway

Contract awarded for Transmission Gully

Initial work will begin over the next few months on the Transmission Gully motorway north of Wellington. This follows today’s announcement by the NZ Transport Agency that the contract has been signed for this project to be delivered as New Zealand’s first Public Private Partnership (PPP) for a state highway.

NZ Transport Agency Chief Executive Geoff Dangerfield says the signing of a PPP contract between the NZ Transport Agency and the Wellington Gateway Partnership for the 27km Transmission Gully project marks a major step forward for the Wellington region.

The Wellington Gateway Partnership will finance, design, construct, operate and maintain the Transmission Gully motorway for the 25 years that will follow the expected five-year period to build the highway. It aims to have the Transmission Gully highway open for traffic by 2020.

The Transmission Gully project’s net present cost is $850 million. This is the “whole of life” cost, for WGP to build and then operate the road for 25 years. Because the costs are spread over time, they are expressed in today’s terms.
Full press release: http://www.nzta.govt.nz/about/media/...3531/news.html

Interesting project, challenging terrain. The motorway will open to traffic approximately 70 years after completion of the Johnsonville-Porirua Motorway.
