Ordinary people can add things to google maps via the map maker. Unfortunately this road is being done incorrectly. You are actually supposed to draw divided roads as two parallel roadways despite the 'divider present' option in the road characteristics. This road should also take the 'Freeway' priority, not 'National Highway', and finally to add state highway numbers one needs to use the full "State Highway 1" and classify that name as only a 'numbered highway' then the maps system will automatically add the red shield.

New Waikanae Bridge taking shape

Quote:
Building a 180m bridge across a major flood plain in a seismically sensitive area like Kāpiti is no mean feat. The team designing and building it faces challenges every step of the way, and we sat down with Zone Design Manager Doug Stirrat to learn more about what's involved.

Why do we need a new bridge?
Well it's really two separate bridges, each carrying two lanes of traffic that will be travelling at 100km/h. Since the Expressway is a whole new road, the new alignment meant we had to cross the Waikanae River in a completely different place. The new bridge stretches 180m across the river, as well as the flood plain, at a height of 5 to 6m. There's a really steep catchment, and the river can rise incredibly fast, so we had to make sure that our bridge was well above the flood plain and strong enough to withstand any seismic events.

And how will it compare to the current bridge?
It's obviously a much bigger structure—180m long rather than the current bridge length of 80m, and four traffic lanes rather than the current two. It will have five spans and four piers. Our urban design team was tasked with designing our "family" of bridges to respect the landscape, so this one will look very similar to the 10 other bridges that are also being built along the Expressway. There's a pedestrian walkway and cycleway on the bridge with links down to the paths on either side of the river. And as I said, we're actually building two bridges that separate the lanes of traffic, so that's very different to the current situation.

But beyond that, we're also building it to an exceptionally high seismic standard. This bridge has been designed to withstand a 1 in 2500 year event, and this is over three times larger than earthquakes that bridges in Auckland would be designed for (because we are a much more earthquake prone area). That's pretty daunting.

So what have you had to do to meet this standard?
This area is prone to liquefaction, so for a start our main bridge piles had to be exceptionally strong. At 3m diameter and sunk to a depth of over 30m they are some of the largest piles ever constructed in NZ. We also had to use a number of different foundation techniques, to keep the bridge safe in case of a major earthquake. One of these is stone columns, which are particularly good for the sandy soils we have to deal with here in Kāpiti. They're also one of the most environmentally friendly ways to improve the ground, as they make use of natural materials (water and stone). We use a powerful vibrator to add stone and compact the ground to a firm foundation.

Another technique is to use steel H-piles under the ends of the bridge, which are more flexible than other types of piles and will give the bridge support that can bend and move with the ground. We start with a vibrating hammer, which vibrates them into the ground, and then a hydraulic hammer drives them down to a depth of up to 15m.

It all adds up to a very strong foundation for the bridge that will be able to withstand a major seismic event and prevent liquefaction from affecting it.

That does sound pretty challenging. Would you say that this is the most challenging project you've worked on?
The ground engineering presents a huge set of challenges here, because no matter how much investigation you do in the lead-up to construction, you really don't know what you're going to hit until you get in. But then over the course of my 30 years in engineering, I've found that every job has seemed to be the most challenging when you're in the midst of it. I will say that working on M2PP is very exciting. I haven't worked in an Alliance set-up before, and it's amazing to see so much construction going on right on your doorstep. Things are happening all over the route and the momentum is really building. It's like we're designing things one day and building them the next. The Expressway is the biggest construction project that the region has ever seen, and I'm really proud of how things are taking shape.

living in Raumati Beach at the moment, not seeing much progress around Raumati road yet. Is it going to be one of the last parts? Looks like the area around Kapiti Road will be complete first?

Here's the completion plan,
http://www.nzta.govt.nz/projects/mac...fo-panel-8.pdf

Basically they are working from the centre to the ends, (although they have preloaded the poplar ave section so its is compacted by the time they come to finish it.

They will use the completed sections as access , so they dont clog up all the local street with construction trucks bringing in tonnes of stuff.

It pretty much all gets delivered to the Otaihanga yards and then dispatched along the haul roads from there...

Thanks for posting this, had not idea whats due for completion when. I'm glad to see that they are planning on fixing the portion between queen Elizabeth park (Mackays Crossing / Raumati South). I was wondering what they were going to do to this piece. This road is currently terrible. It looks like the "Raumati Straight" will be completed by June 2015 so we can expect major roadworks there from early next year.

That is a good way to do it, especially with how close that part of Otaihanga is to the state highway.

Major works now happening at the Kapiti Rd over bridge.





Not sure what the plan is here and how they are going to complete the bridge without affecting traffic on Kapiti Rd. I suspect they will leave traffic diverted until the northern side of the bridge is complete, and then resume traffic under the completed northern side of the bridge while they complete the southern side.

I read in the newspaper that work is starting there this month.

From the Express lane blog:

Quote:
Work around Raumati Road is scheduled to get underway this month. You’ll see big changes to the local landscape as we start to clear vegetation and large trees along the Expressway route. We’ll be putting up fencing to keep people safe and out of the worksites – this means the informal footpaths that have been used this area will no longer be usable. We’ll put signage up advising other routes. Please remember works sites are extremely dangerous places. Fences and signs are there for your safety so please respect and observe them.

Earthworks and pre-load next to Poplar and Leinster Avenues continue and State Highway still has a 70km/h speed restriction in place for northbound traffic.

Have already noticed the land moving around the hillside of where it is going, fairly impressed at how fast they've moved on it.

Yeah, there are a couple of good recent aerial shots on the M2PP flickr account, that show the kapiti road site from the air, ( although for some bizzare reason they are not in public domain)-
its clear that the Northen span will be the first one done and Kapiti road will re reouted back under there while they complete the southern section.

110kmh limit moves closer

Quote:
The Government is warming to the idea of a 110kmh speed limit on the best roads - and has confirmed it is under serious consideration for several new motorways, including Transmission Gully.

Transport Minister Simon Bridges said he would be open to discussions about raising the present 100kmh limit if the New Zealand Transport Agency felt there was a good case for it.

Ernst Zollner, the agency's road safety director, confirmed yesterday it had been "mulling the idea for a good year at a strategic level", after research from Monash University in Melbourne suggested it could be done without increasing the risk to motorists.

A 110kmh limit was being considered for motorways built as part of the Government's roads of national significance programme, provided they were flat, straight, had two lanes in each direction, a median barrier and good shoulder space.

Candidates included the Transmission Gully motorway and Kapiti Expressway in the Wellington region, the Waikato Expressway, the Tauranga Eastern Link and the Northern Gateway toll road north of Auckland, Zollner said.

Bridges said he would wait to see what the agency's investigations turned up before deciding whether to progress discussions around the law change required for a 110kmh limit.

"But I think what is true is that, if the road design . . . can safely allow for different speeds, then we should at least think about it," he said.

"So that's where we are at the moment - we're at the 'thinking about it' stage."

His tone on the topic is more optimistic than that of former associate transport minister and present Police Minister Michael Woodhouse, who told The Dominion Post last month he did not feel the condition of motorways was consistent enough yet to warrant a 110kmh limit.

Zollner said the change was being considered as part of a wider review that could see some speed limits reduced to better suit the road design and environment.

"For many roads, no change to travel speeds or speed limits will be needed," he said. "It is for those roads at the margins, where the current travel speeds or speed limits may be too low or too high, that changes could be made."

He expected the agency would present its views to Bridges by the middle of next year.

Any increase to the 100kmh limit would require public consultation.

While Bridges would not rule out changing the law, he was concerned about the implications of allowing drivers to travel at 110kmh when the average age of the vehicle fleet was 13 years - quite old by developed-world standards.

AA motoring affairs general manager Mike Noon said he was encouraged to hear Bridges was open to the idea of a 110kmh limit.

"From our perspective, it's only fair that, if some speeds are going to come down to better reflect the road, then some should also go up, where possible."

Australia and Canada have motorway limits of 110kmh, while Britain's is 70mph, or about 113kmh.

You'd have to put it on the gully, I'd even put it up to 120km/h.

Haha.. speed limits, judging by the comments on stuff... are an area where New Zealanders as a whole don't understand logic, and no amount of science will convince them.

Personally I'm just glad to see these roads go ahead. My mother's childhood property was backed onto land allocated for it... when she was a child... in the 1950s.
