What about communities of national significance?

by Gareth Hughes

Transport will be one of the big local issues of the looming Mana by-election. The Kapiti Expressway, currently being rammed through as a Road of National Significance project by the Government, is attracting considerable opposition because it is an unpopular, unsustainable and uneconomic 1950s-style solution. Rather than a smart, integrated and affordable solution, this project is like hitting a nail with a sledgehammer though the community.

The Green Party believes the John Key-led Government is wasting billions of dollars on uneconomic motorways like this one, locking us into a car and oil dependent future.

The Greens believe in smart transport investments that balance roads with sustainable transport options (bus, rail, walking, cycling, rail and sea freight) that will future-proof our transport system so that it is more affordable, efficient, and versatile. We’re proud to have been the champions of transport choice. We’re finally seeing the completion of many of the improvements in the Wellington region, such as the fleet of new electric trains and the extension of electrification and double tracking of the lines to take commuter services to Waikanae, that we’ve been calling for years.

The Greens are not anti-car or anti-road. We love to drive. We are pro-transport choice. We recognise building local roads can play a valuable role in stimulating economic growth and smoother roads make it cheaper and greener to drive. We don’t want to stop all road investment, just stop pouring billions into white-elephant motorways that will make congestion worse, and dramatically affect the Kapiti Coast community.

This road is part of the region-wide Western Corridor project, which is one of Government’s seven Roads of National Significance. I think a more accurate way to describe it is a road of National Party significance through a community of national significance.

Two decades ago, in 1990, the then Commissioner for the Environment, Helen Hughes, investigated what would be the most effective way of solving congestion on the so-called Western corridor. She concluded that upgrading the rail service, not building a new motorway, was the solution. She said then, “It is symptomatic of traditional transport planning systems that options that require huge earthworks and disruption for whole communities are seen as realistic, while anything that would require a reordering of priorities or a change in behaviour is seen as unrealistic”. How true, and prophetic.

This new expressway between MacKays to Peka Peka is tremendously expensive. It’s going to cost up to $500 million, which is an awful lot when we are borrowing as a nation $240 million a week. A case could be made if the benefits were great but this project is uneconomic and has a benefit cost ratio of only 1.1, which means the benefits only barely exceed the costs.

If we took into account likely future oil price fluctuations and increases and actually measured the public health, road safety, and pollution costs this project wouldn’t come close to stacking up.

The big question is however, is an expressway even needed? Along with more noise and air pollution the impacts locally are going to be physically cutting Waikanae in two, and crossing the spiritually significant Takamone wahi tapu. Many locals feel betrayed that the originally favoured and widely consulted-on Western Link Road, which was to be a 50-70km local road and walking and cycling route to take traffic off SH1, was thrown by the wayside by Steven Joyce when he announced his new Wellington Road of national significance. It’s going to take a long time to build and ultimately benefits through travellers and trucking companies more than locals.

Many people do want congestion and safety improvements on SH1 but this expressway is an Auckland-style solution that seeks to solve congestion with more motorways. It has failed there, so why do we suddenly think it will work here sixty years later?

The answer locally is a balanced system that invests more modest amounts in public transport, walking and cycling; safety improvements on SH1; and a new local road. This should be a corridor of national significance, not just an expressway.

Rail locally and globally is undergoing a renaissance, in part because it is better for congestion. A lane of motorway carries only 2,400 people an hour, whereas a rail corridor carries 20,000 people an hour. It is greener, less dependent on oil, and importantly is much safer. Trucks are a major cause of accidents on our roads, responsible for 16% of fatal accidents on our roads even though they only account for 7% of the total distance travelled by vehicles in NZ.

A fast, reliable and frequent modern rail system, coupled with other transport choices, would boost local amenity and economic development. Ironically, a key improvement to Coasters’ transport choices would be in Wellington. A light rail system linking the railway station to the hospital and airport would make getting where you need to go in Wellington for work and play easier and faster.

This expressway is a big expensive white-elephant, but it isn’t a forgone conclusion. Even though the New Zealand Transport Agency is ploughing ahead, it is essentially a political decision. As was demonstrated over the Schedule Four mining issues, public pressure influences this government. There are lots of local opportunities to send a strong message to the Government before construction starts in 2012, such as the local body elections, the Mana by-election, the general election next year, and the petition circulating by the Alliance for Sustainable Kapiti. The economics don’t stack up for the project and a little collaboration, analysis and lobbying by local government and community groups could force a big shift. Other communities have halted big, dumb projects like this and Kapiti can too.
