I don’t often propose new roads on this blog, but there are a couple of possible new bridge connections around Auckland that I think could be very useful additions to our roading network and would potentially be more useful ways of spending our roading budget than on forever widening motorways. The first is the possible Whau River bridge between Te Atatu South and the Rosebank peninsula that I discussed last month. The second possibly useful additional bridge is one between Beach Haven and Greenhithe on Auckland’s North Shore. Effectively, the idea would be to build a bridge somewhere along the blue line’s alignment below, which would mean that vehicles and people (including buses, cars, cyclists and pedestrians) wouldn’t need to take the very long way around any more (indicated in red): The stretch of water the bridge would go over is only around 500 metres wide, and as I don’t think there are particularly many boats which head up this arm of the Waitemata Harbour, the bridge wouldn’t necessarily have to be that high. So I don’t see it as being a massively expensive project.
In terms of its benefits, probably the main one is the reduced travel times (real time savings benefits!) Of not having to go the very long way around via Glenfield. This would save around 15 minutes off each car journey and obviously more for pedestrians (not that there would be any at the moment) and cyclists. It would also bring Greenhithe much more obviously into the North Shore and provide better access for those in Beach Haven to areas like Albany, Westgate and west Auckland in general. The map below shows how long a trip from Beach Haven to Greenhithe currently takes, according to Google Maps (probably on a day without any congestion):You need to drive almost 11 kilometres as a detour just to go in a straight line what is well short of one kilometre. That’s pretty inefficient.
There would also potentially be many public transport benefits arising from such a bridge too. Making the trip shown above on public transport is nigh on impossible:
It seems crazy that it would take so long for a trip that’s barely a kilometre as the crow flies. Now obviously there aren’t too many employment opportunities in either Beach Haven or Greenhithe so getting exactly between the two places isn’t a massive concern. However, there are employment hubs like Albany, Westgate and Henderson that people living in the Beach Haven/Birkdale corner of the North Shore may want to have somewhat reasonable access to – and a bridge like this, with a bus transfer point at Greenhithe onto the 130 route (which would hopefully be straightened up a bit) would provide the kind of connection sorely lacking at the moment. You could end up with something like this: The blue line indicates the current 973/974 buses, which run fairly frequently between Beach Haven and the CBD. The red shows part of the 130 route that potentially offers a great cross-town connection (though I have straightened it up in line with a discussion in this blog post).
There would obviously be some negative effects of the proposal. There would be a street in Beach Haven that’s very quiet at the moment which would become very busy. There may be difficulties in “landing” the bridge at its northern end. There may be environmental effects as this seems like a fairly sensitive corner of the harbour and there would obviously be the cost of the proposal. But at the same time I think there would be quite major benefits: for all type of potential users (drivers, bus riders, cyclists and pedestrians). Perhaps most useful it could link Beach Haven and Greenhithe better with each other and better with Auckland as a whole as they’re two quite strangely isolated parts of the city at the moment.
