Labour’s announcement on the weekend that they would provide $1.2 billion to help construct the City Rail Link was credible because they have a source for the funding: redirecting the money from the Puhoi-Wellsford project which is often termed the “holiday highway”. The January 2010 project summary statement noted the following ‘forecast outturn cost’ for the Puhoi-Wellsford road:

The final costs of the RoNS corridor will include future years escalation (normally three percent) due to increases in input costs largely following national economic inflationary pressures. The actual amount of escalation attributed to individual projects depends on the time frame for the construction. If a project is constructed earlier than predicted then the amount of escalation would be lower. Equally if construction is later than predicted the cost of escalation would be higher. However, at a RoNS corridor level the individual project effects are less marked. Thus the forecast outturn cost of the RoNS corridor would be $1.69 billion with a confidence range of $1.53 billion to $2.04 billion.

So our best cost-estimate for the project is around $1.7 billion, meaning that Labour’s policy of redirecting $1.2 billion onto the City Rail Link is not only easily possible, but also leaves around $500 million to spare. Usefully, a key part of the announcement on the weekend effectively picks up on a piece of work that I did along with the Campaign for Better Transport back in 2010 – to come up with a more cost-effective alternative to the “holiday highway”: something we called Operation Lifesaver.

Operation Lifesaver was initially presented to the Transport and Urban Development committee of the former Auckland Regional Council, to help inform their submission on the Puhoi-Wellsford project. It was generally fairly well received, particularly the focus on safety. You can read the whole document here. The summary is outlined below: As you might be able to guess by its name, the purpose of “Operation Lifesaver” was not just to find a cheaper solution to the full Puhoi-Wellsford motorway, but to come up with some safety improvements in particular that could be implemented a heck of a lot faster than constructing the full motorway. This is because the current road is extremely dangerous – this slide comes from our presentation to the ARC (figures from the NZTA business case document): With the Puhoi-Warkworth section not due for completion until 2019 and the Warkworth-Wellsford section until 2022 (likely to be even later now due to geotechnical difficulties) we worked out that around 50 more people would die, based on trends since 2000, before the full motorway was opened. That was a pretty shocking number and drove a lot of the thought behind trying to come up with a solution that could be implemented a lot sooner than the full-blown motorway.

With a lot of helpful input from an NZTA Official Information Act response, we put together two options for more immediate upgrades to state highway one between Puhoi and Wellsford: largely safety improvements as well as a Warkworth bypass. 

Of course we are not transport economists or engineers so there was a bit of guess work in the assessment of costs and the assessment of cost-effectiveness, but this was done fairly conservatively on a “what proportion of the full project’s safety/time-savings/vehicle costs etc. benefit are we likely to get from this” approach. It would be interesting to get a bit more expert analysis of the idea – particularly now that Labour have effectively committed $320 million to State Highway 1 between Puhoi and Wellsford. I suspect that what we could get for that price might fall somewhere between the two proposals, as things are always a bit more expensive than you thought.

It’s important to keep in mind, when looking at policies to “abandon the holiday highway” and “do Operation Lifesaver instead”, that Operation Lifesaver is a fairly extensive proposal – particularly if you have $320 million to play with. Many of the congestion issues faced by this road are caused by Warkworth and would be solved by a bypass. Many of the safety issues could also be fixed much more quickly and efficiently if we don’t have to wait 10-20 years for the full motorway to go through.

One argument made for the Puhoi-Wellsford road is its ability to help Northland’s economy – perhaps in a way that Operation Lifesaver can’t (if we set aside the relative costs of the options for now). While I can’t really see how savings 7-10 minutes off a trip between two Auckland towns will revolutionise Northland’s economy (and a Warkworth bypass would generate much of this time saving anyway), I think the last word on the issue of economic development should go to a 2008 report commissioned by NZTA into the upgrade (just before it was nominated as a RoNS): In short, while there would be some economic effect, it would be pretty minor. Certainly not worth spending $1.7 billion on when there are better alternatives around.

  1. How deeply have you investigated the three lane tidal option. My gut feeling says that you would need a movable barrier for safety (we have one on the harbor bridge cos of a spate of fatal head on collisions. My gut instinct also says that a moviable barrier will be infeasible on a non-straight section of road.

    Do we even need that capacity if the bottle necks are removed? A passing lane or two on uphill stretches would be nice.

    1. Not particularly deeply and I agree it may be unnecessary/impractical. Once Warkworth has been bypassed I think you would reassess the congestion issue before going anywhere further.

      Obviously the safety upgrade is a separate issue which you would want to do ASAP.

  2. A useful summary, admin. I’d forgotten about NZTA’s economic summary. Was a revised BCR ever done after the announcement that the Holiday Highway ( love it how the name has stuck!) would be a toll road? Presumably there has to be a figure on how much the toll will be?

  3. ‘While I can’t really see how savings 7-10 minutes off a trip between two Auckland towns will revolutionise Northland’s economy’

    It would be great if someone could name one Northland business just waiting to turn into a world beater that is currently constrained by the extra 7-10 minutes of travel.

    1. Indeed, arnie03. The same company would have to have a policy of not permitting toilet breaks or overly long stops at the pie shops along the way to be credible in its demands for a new toll road.

    2. Fair point and I’m not disagreeing with you (quite) but how much has been spent in Auckland to save people 10 minutes?

  4. Interestingly enough, the AA, the so-called independant motorists service, has blindly come out fully supporting the National Govt and their expensive holiday highway, rather than what is best for motorists safety.

    Since when did the AA become political and promoting the National Government’s projects instead of promoting common sense projects supporting safety of motorists?

    AA – the confused National Party advocate?

  5. A few points to note on this.
    Phil Goff was misquoted in the Herald on release of the Labour transport policy. It was reported that he said he would “cancel the upgrade to SH1”, which is not what he said at all. In fact he said that he would cancel the construction of the 4 lane highway in favour of upgrades to the existing highway, a scheme based on “Operation Lifesaver”. Subsequent correspondents in the Herald have jumped on the bandwagon and accused Goff of severing the potential lifeline to Northland.
    Rodney councillor Penny Webster was quoted spouting the usual claptrap in today’s issue of the Rodney Times as saying that she knows that this is the “Umbilical cord for the north – it’s a Northland project”.
    The Auckland Spacial Plan makes mention of the highway, but no access at Puhoi/Mahurangi West, which Mrs Webster and Lockwood Smith have also promised will be delivered.
    The proposed highway is only intended to go to just north of Wellsford (which is only half way to Whangarei) by 2032 – another 21 years from now.
    If this truly was a project to provide a link to Northland, then the existing motorway would have been built much further to the west and would currently terminate in a paddock somewhere near Kaukapakapa.
    The Auckland Plan makes mention of further development in the coastal areas to the east of Warkworth and Wellsford (again see the proposal for a Plan Change in today’s Rodney Times for a development at Te Arai, which is the tip of the iceberg)
    Blocks of land in this area are already being sold as “near to the proposed motorway access” and with “potential for sub-division when the new Motorway is built”
    Road usage figures from NZTA show approx 17,000 movements per day Warkworth to Puhoi, but only 9,000 per day Warkworth to Wellsford, which demonstrates that a large proportion of the journeys eminate from or terminate at or near Warkworth (Eastern beaches for example).

  6. Warkworth needs a bypass? Yeah right – this keeps getting trotted out as if a bypass will fix the problems. As a resident and someone who has daily commuted between Warkworth and the CBD I can categorically state that the ONLY time that I have seen congestion is either major holiday periods (and then only for a day each side of the holiday time-frame) or on those tragic times when someone has died in a car accident. What needs to happen before we spend a lot of money on a bypass is the following:
    • Extend the 4 lanes from the Woodcocks Rd intersection with SH1 right through to Hill St intersection (making the current 2 lane bridge before Hill St a 4 lane bridge);
    • Sort out the Hill St intersection so that through traffic flows freely;
    • Implement the already planned Western Collector (the road that was designed to go from SH1 at McKinney’s intersection down through a housing development (where the developer was going to pay for some of the road) and then on out to join up with Hudson Road which joins SH1 to the north of Warkworth.

    SH1 was the original Warkworth bypass – no-one driving North these days goes down through the town to get north – they sensibly use SH1. That Rodney Councils over many years have condoned ribbon development along SH1 is something that they may now, with hindsight, wish they had avoided. However, one of biggest elephants in the room are the two schools which now find themselves slap bang on a busy state highway. Perhaps, given the planned major development for the area, we should be thinking of moving those schools to a safer environment surrounded by what they currently don’t have – space.

  7. People from Northland feel your pain, we understand you may feel that there hasn’t been enough investment in Auckland.
    It is the same for Northland, but Northland has less people and less of a voice. Northland’s transport needs are less about getting commuters to work on time than getting produce to the consumers. Don’t put more money into a Auckland rail link if it has to be done at the expense of Northland’s transport future.

    Since I moved from Wellington to Northland, I realise it gets a poor deal. It has less jobs in the finance and commerce sectors, based more around the productive sector and tourism.
    Northland is actually an important contributor to New Zealand’s economy but is strangled and cut off from the rest of NZ. There is a high reliance on the route that links it to the rest of New Zealand via Auckland. The route needs to be made reliable, secure , safe, enjoyable and future proofed.

    There has long been limited investment in Northland transport. All aspects have suffered; roads, public transport, walking & cycle facilities, airports, rail lines, wharves. A road link that is available for the long term is one of the vital components for the future of Northland.

    1. Agreed that Northland infrastructure needs investment. But blowing 2 billion+ in the AK ex-urbia is not it. Remember the planned road is a duplicate; there are already two highways heading this way already; SH1, and SH16, and a rail line. All of which need upgrading, but not duplicating. This is a daft and foolish plan that can not possibly ‘transform’ or even marginally improve any economic performance in Northland, except for a few contractors during the construction phase.

      It is an overblown subsidy for landbankers on AK’s fringe.

    2. The $1.7 Billion that it is forecast to cost (and no-one yet knows what it will finally be because of the difficult terrain through the Dome Valley), would be much better spent dealing with precisely the problems that you detail John. Invest in upgrades to the 2 existing roads, spend the money on retaining the railway and creating the link to Marsden Point and take some of the freight off the roads. Deal with some of the shortcomings in the existing infrastructure within Northland and create some worthwhile jobs. If Phil Goff had a bit more savvy, he would have promised to spend some of the money saved on this ridiculous scheme exclusively within Northland. Heaven knows, they need some investment there.

  8. Yes, you’re right Bob, Northland certainly needs some investment. less influence up north but perhaps 10% might be able to be retained to be used for improvements to the existing route? I see it has now been renamed from “holiday highway” to “road to nowhere”.
