Yesterday Stuff published what is frankly an odd opinion from Mayor Phil Goff regarding public transport and a future harbour crossing.
Auckland Mayor Phil Goff would prefer the city’s second harbour crossing to be built with a busway instead of a rail line.
Goff said the $4 billion tunnel under Auckland Harbour, planned for about 2030, should be built with a busway to begin with.
“Busways are easily translatable to light railways, so the two are quite compatible. You may sequence it in that order. That’s my preference,” Goff said.
Goff said he was keen for a rail line to Auckland’s North Shore, eventually, but a rail line to the airport was a higher priority.
There are quite a few things that spring to my mind from just these few lines.
The busway is an outstanding success and use of it has grown dramatically in the nine years since it opened. It now carries over 4.6 million trips annually which is not all too different to what our rail lines do.
One of the big transport issues facing Auckland and especially the city centre is how we cope with growth in public transport. As it is now many streets in the city centre have too many buses on them and are struggling to cope, let alone what would be needed if public transport use keeps growing like it has been. This is of course the main reason AT were looking at Light Rail in the Isthmus. On top of this is the city’s desire to become more walking and cycling friendly.
The northern busway itself still has capacity left for a while, at current rates probably till some time in the 2030’s, but even that means we’re likely to need to look for further ways of improving capacity within the next 20 years which is exactly the timeframe we’re going to be discussing the next harbour crossing. If we’re going to the trouble of spending possibly billions on another harbour crossing it makes no sense to build it as a busway if we’re only going to have to upgrade it again in few years time.
Goff campaigned on light rail down Dominion Rd and he’s quoted as saying that rail to the airport is a higher priority. I agree with him on that but it doesn’t mean we don’t discuss it for the North Shore. In fact, the two could even link up together to deliver a light rail rapid transit line from Albany to the Airport. That’s a vision I bet a lot of the city would get behind.
I also suspect Goff is underestimating the impact of converting a busway to light rail, especially the disruption it will cause. This won’t be a quick few weeks job but would likely take months or even over a year depending on how it was done and during that time the busway will be out of action. While I’m sure some of the smart people in our transport industry will find ways to minimise that, it will still be incredibly disruptive and we wouldn’t want to have to do both the existing busway and a busway harbour tunnel, even if it was possible.
It’s important to remember though that the timeframe listed, of a harbour crossing “planned for about 2030” is actually incorrect anymore. The recent ATAP work pushed the project back to completion in the 3rd decade (2038-2048), in part due to the work showing it as having a very high cost while having little impact on congestion. The current plans for the next crossing envisage a combined tunnel with road and rail combined. I can’t imagine that would be too save with buses though it and certainly not double deckers.
We believe there’s a strong case to separate out the PT and road crossings and build them separately, starting with the mode that doesn’t currently exist. This is also because a PT crossing would have considerably more capacity than any road crossing would. We also think it’s time we reconsidered the option of that new crossing being a bridge. Like the new Tilikum Crossing in Portland it could be for PT and active modes only, and would considerably cheaper than tunnel options.
Let’s hope someone tells Goff that a busway tunnel is a bad idea
