Otaki expressway on fast track


The at-least $250 million northern section of Kapiti's expressway has been put on the consenting fast track.

Environment Minister Amy Adams announced today that an application for the Peka Peka to Otaki expressway will be decided by a board of inquiry.

"This process will enable affected people to have their say but will deliver a decision within nine months," Ms Adams said.

The boards were set up by the government to fast track the consenting process for projects of national significance.

The board will be chaired by retired High Court judge Sir Hugh Williams, joined by resource management experts Pamela Peters and Morrie Te Whiti Love, resource management and civil engineering expert Jeffrey Jones, and roading expert Mark Apeldoorn.

Ms Adams said the application is nationally significant because of its use of physical resources and natural resources, the wide public interest in the project, and because it is part of a network which extends to more than one region or district.

The NZ Transport Agency lodged the application in March - weeks after a draft board decision approving the $630m MacKay's to Peka Peka section of the Kapiti expressway.

The latest application relates to the construction, operation and maintenance of the expressway and the construction, operation and maintenance of a section of the Main Trunk railway line.

The project would include a new four-lane expressway running alongside the existing State Highway 1 alignment through Te Horo.

It would bypass Otaki with connections to local roads and new bridges over the Otaki River and Waitohu Stream.

Detailed design on the project is expected to start next year and construction in 2016.

Work on the southern section of the expressway is expected to begin this year and be completed by 2017.

good to see they're fast tracking it. wouldn't want the pesky local community getting in the way of progress:lol:
You mean a small minority of the local community.

Concern over expressway bridge design



A new Otaki River bridge proposed for the Kapiti Expressway could become a sieve, snagging debris and clogging the waterway, a consent hearing has been told.

Sharyn Westlake, of the Greater Wellington Regional Council, said the design proposed by the NZ Transport Agency was not the type recommended by the council.

Ms Westlake was a witness for the council yesterday at an independent board of inquiry hearing into the agency's proposed $250 million, four-lane expressway between Peka Peka and Otaki. The board is part of a fast-tracked consenting process for projects of national significance.

Ms Westlake said she did not support the twin support columns, called piers, proposed for the new expressway bridge. The regional council's preference for flood protection was for single-pier bridges.

"Twin piers inevitably build up greater amounts of debris than single piers, not only because of the difficulty of lining the piers up with the flow, but also because the twin piers cause the flows to behave differently around them."

The double piers created "vortices" in the current, which gathered debris and scoured out shingle, she said.

Under questioning from the agency's lawyer, Ms Westlake accepted there would be further modelling on the impact of the double columns.

She accepted there would be specific plans for managing the environmental effects of all the bridge designs, including the piers, in the entire project area.

Much of yesterday's hearing in Paraparaumu dealt with the impact of the project on flood-prone areas along its 15-kilometre length.

Transport Agency expert witness Grant Webby said the expressway would be exposed to the same flood hazards as the existing SH1 and main trunk railway.

His modelling on the effects of the expressway were based on floods of a high magnitude that would, on average, occur only once in 100 years. It included the impact of climate change through to the year 2130, he said.

"My opinion is that flooding occurs naturally, and it's a fact of life."

Maps tabled at the hearing showed the expressway would create small pockets of new potential flooding areas, but would also cut the risks in previously flood-prone areas. The expressway design sought to minimise the flooding impact upstream, he said.

The Peka Peka to Otaki expressway is the northern half of what will be known as the Kapiti Expressway. The southern half, from McKays Crossing to Peka Peka, has received resource consent but its construction has been stalled by High Court appeals.

If consent is granted, construction of the Peka Peka to Otaki section will start in 2016 and be finished by 2020.

The hearing, with a five-member board chaired by Sir Hugh Williams, began on Monday and is set to run for two weeks. It continues today.

Levin plan 30 kilometres long beginning construction on 2021 take five years
Cost 2 Billions dollars they also plan 110 kilometres per hours unknown location start to end

The Levin expressway extension cost is ~$100 odd million, its pretty rolling country with stable soil and no major bridges required,

The $~2 billion cost is the total cost of all the "Northern Gateway" roads
=Transmission Gully ($850m) +M2PP ($600m) +pp2o ($330m) + pp2l ($~100 m)

$100m is the figure being bandied about because “$100m+” is the largest cost category NZTA use on their website, which is where media get all their info from when they can’t be bothered researching.

Even the $1.4b Waterview tunnels would have been listed as a $100m+ project on the NZTA.

O2NL is likely to cost tens of millions for land acquisition alone. I’d expect it to cost at least as much as PP2Ō. The bridges are less significant but the route is longer I think.

I was past them they’re doing clean up tree make way for Motorway
Drilling holes for bridge
Once complete 12 kilometre long in 2020 then they’re plan additional more further up 30 kilometre beginning in 2021 take five years construction
They’re now options for while

River diverted as Peka Peka to Ōtaki expressway gets set to cross water

The Ōtaki River has been diverted as work to bridge it ramps up.

Contractors building the $330 million Peka Peka to Ōtaki Expressway have shifted the river's gravel to create a temporary platform to sink the last two sets of piles into the river bed.

Once completed, construction will shift to the northern side of the bank and the river would return to its natural course.

now only going to be 1 lane each way.
I will wager real money this (even the single carriage way version) will never be built under the current govt... (It would take at least 3 years to get designs and resource consents)

between 00-07 Labour / Greens supported the whittling down of the "Sandhills motorway" through kapiti into a single carriage "western link road"... but they couldn't even get that through to construction....

It was only after the 08 election that the current expressway was designed and built......

Otaki to Levin will be built as a 4 lane road but it wont happen for probably 6 years....

Building 4 lanes north of Otaki would be nice but is probably a waste of money at the moment. The congestion problems occur in the towns where you have lights and/or give way signs. If you could build short diversions around Levin , Foxton, Sanson and Bulls (and Featherston, Greytown and Masterton)you will solve most congestion problems in the lower North island. It still will not stop all congestion as each time you just push the problems further north but it would be a start.
Traffic moves quite well if the speeds are kept at 95-100 Kph so as long as there are passing bays to get past the odd slow vehicle.

Agreed. It would be far cheaper to build high speed bypasses and have 2+1 roads with barriers in place along with large roundabouts at the busier intersections.
