We know that Auckland’s transport plans are completely unaffordable, a more interesting question is “why?” Much of the answer to that questions comes from what I refer to as “overkill”. Essentially, a solution that’s vastly oversized compared to the problem it’s trying to solve. There are a large number of examples of “overkill” when it comes to transport projects currently being planned:
- The East West Link is perhaps the most obvious example, where somehow a bit of congestion around a couple of intersections at each end of Neilson Street somehow led to NZTA and AT proposing a gigantic and enormously destructive motorway through one of the most densely populated and deprived parts of Auckland. Yeah there are certainly some transport problems in the area but the jump to a huge motorway solution is a classic example of overkill.
- The proposed motorway to motorway connection between SH1 and SH18 at Constellation Drive. The problem here appears to be a pinch point northbound on SH1 between SH18 and Greville Road and constraints around the interchanges themselves. Yet again the solution is to jump to a gigantic motorway-to-motorway mini-spaghetti junction that likely to cost upwards of half a billion dollars. What about just adding another lane northbound, extending the Northern Busway to Albany and then seeing whether anything else is actually necessary?
- Puhoi-Wellsford is another classic example of overkill. Yes there are congestion problems around Warkworth, yes there are major safety issues in the Dome Valley and at specific points south of Warkworth, but it’s quite a jump to suggest the only solution to those problems is a massive new motorway that’ll cost close to $2 billion. Operation Lifesaver highlights how most of the benefits from the motorway can be achieved at a fraction of the cost by truly focusing on the problem at hand.
- The recently proposed Lincoln Road widening project once again responds to legitimate problems like a lack of priority for buses, localised congestion and safety issues. Yet the respond is again overblown – massively wide intersections, slip lanes everywhere, extra lanes all over the place etc. The outcome is not just an overly expensive project, but a corridor that gets wider and wider – further degrading the urban form around it.
- Penlink is a massive project to satisfy locals when the real problem is further north at Silverdale and can be solved with other smaller alternatives.
It seems like good transport planning should flush out what projects are overkill and what projects aren’t. An interesting comparison against the above projects is the process that the City Rail Link has gone through over the past few years – especially in the form of the City Centre Future Access Study, which looked in detail at a range of “smaller options” for resolving issues with access to the city centre – outlining which of these would be necessary anyway, which could occur prior to CRL being built but also the point at which the ‘small scale’ interventions need to become so significant you might as well do the job properly – in this case by building CRL.
Throughout the ITP there are a vast number of projects which are obviously “overkill”. Examples include $665m on Albany Highway (surely a typo?), around $800m on a section of Great South Road, a $150m motorway bypass of Kumeu, the $240m Mill Road corridor project and many others. Strip back these overkill projects so they really focus on the problems they’re designed to resolve and we’ve probably gone a long way towards solving our future funding shortfalls.
