Auckland Transport History - Part 4

Following is Part 4 of my series on Auckland's Transport History.

As before, this series is sort of in response to a paper I read:
"The American Heresy: Half a century of transport planning in Auckland"

Recap:

To recap from the previous posts there have been 3 main transport plans developed for transport in Auckland, these are:

• 1946 Regional Transport Plan
• 1956 Auckland Plan
• 1965 Auckland Regional Transport Plan

Of these plans, the 1946 plan presented a regional road network that was outside of the Auckland urban area.

The 1956 Auckland Plan reduced the regional extent of the previous plan but envisaged an extensive series of motorways wrapping around all 4 sides of the CBD. Of the 35km of inner city motorways that were planned in the 1955 plan only 4km (10%) of these were built during the years 1955 to 1965.

The 1965 plan was the most extensive of all the plans and included both an extensive motorway network and rapid transit network. Approximately 65km of additional motorway was marked out over the urban area of Auckland, however in the 50 years since this plan was put in place only extra 20km (30%) of these urban motorways have been built. Of the RTN component roughly 75km was marked out to cover existing urban areas, the existing rail lines made up 50km (65%) of this network however nothing was added to this until 2008 when the Northern Busway was opened.

When you look at Auckland today it may appear that Auckland has an extensive urban motorway network, however this network is actually a result of Auckland growing and following the regional motorways into the country (similar to the Waikato Expresssway) rather than these motorways being planned as urban links.

In terms of what was planned inside the urban area it has taken 50 years to complete roughly 40% of what was planned to be delivered over 20 years. In terms of the rapid transit network; 65% of the urban area was was already covered by the existing rail network, however slow and unreliable service meant it was never operated as a rapid transit network.

Auckland Councils Part:

As we have seen, the various plans were all regional plans and were mainly in relation to the surrounding areas of Auckland rather than the urban area itself. Of the routes that went through the urban area, the ones that were built were intended to connect the northern, southern and western areas of Auckland but also provided access to the CBD.

The above regional connections were all delivered by the government as building and maintaining regional connections is managed and delivered at a national level. When it comes to local transport needs such as local arterial roads, bus services and metropolitan rail the local council generally manages the delivery. So while the government built their regional state highways what did the Auckland Council get up to?

Well it turns out, they didn't do much of anything.

One thing the council did do is remove the tram network and replace it with buses, this was done with the intention of making PT faster and more flexible. It's not overly clear how well thought through this plan was as the bus terminal in the city was built in 1937 when most PT users took trams yet no upgrades were made when the tram network was replaced with buses.

The other thing the council did between creating the various transport plans was sell off land and approve construction of housing and industrial developments where these planned transport links were intended to go.

The councils worst contribution however was to prevent these future routes being built  by building local roads along the planned alignment with property access for the full length. For any transport link to be effective at moving freight or people is to reduce side friction, being property access and intersections, however the council maximised side friction meaning these links become trapped as low speed urban roads.

One example of this is Ti Rakau Drive, this road was planned to be "expressway standard" meaning no side access but some high standard at grade intersections. Although for a time this road would have been rather nice with little traffic and wide grass berms, as the city has grown it has become a constraint on the area and not the most ideal street to live next to.

Slightly better is Te Irirangi Dr which does have some level of access control but rather than being an expressway is a partial boulevard. With this section being posted at 80km/h with various major signal controlled intersections its not a very safe route to drive. Adding to this are poorly design entrances and exists from side lanes along with trees in the median which makes it understandable that there have been some serious crashes here in the past.

One of the merits of this route is that they did try to future proof for rapid transit with the wide grass median, however this is appears to not have been thought through all that well as there is no logical place to have stations in the middle of the road and every intersection would need to be grade separated.

Robbie's Rail:

One of the things the Auckland council did do back in the day was try and stop the CMJ. Although first planned in 1956 and scheduled to be completed by 1976 by 1970 the only connection that had been built was a now removed bi-directional link to Wellesley St.

Although quite a bit of rural motorway had been built with few issues over the previous 20 years the work on the highly destructive inner city section was only just starting. It is estimated that as part of building both the CMJ and the southern motorway from Ellerslie that some 15,000 homes were destroyed forcing the relocation of some 50,000 people and so it it understandable that it was not very popular at the time.

Adding to the disruption that was going on as part of the building the CMJ, congestion levels were growing as the city had grown along the rural motorways letting users quickly drive into the city but then being left to use the existing local roads through the most congested parts of the city.

In the lead up to this when the full costs of the CMJ were starting to be appreciated the Mayor at the time (1968) Sir Dove-Myer Robinson championed the scrapping of the CMJ and building an inner city loop, similar to the CRL of today, as the way forward out of Auckland's congestion. The design presented was pretty much the RTN design from the 1965 Regional Transport Plan and the idea was to build the rail link first rather than scrap the CMJ altogether.

Given the size of the proposed inner city loop and the technology at the time this rail link would have been similar in terms of extent of destruction as the CMJ was and would have likely resulted in the loss of a number of historical buildings in the CBD. In the end the rail scheme was put on the back burner and plans for the CMJ continued.

Not long after this the world experienced the biggest and longest spike in world oil prices with oil prices increasing by up to 600% and taking 13 years to return to normal prices. This oil price increase resulted in a large increase in PT usage which would have meant many of the public would have seen the continued progress on the CMJ as a waste of money when PT funding was needed, however as soon as the oil prices when back to normal PT usage also declined to the lowest annual usage in Auckland's history.

Between 1970 and 1978 the southern and northern motorway's where connected at the CMJ and in 1983 the northwestern motorway was connected. However it took till 2006, 30 years late, to complete the various ramps and Dominion Road was removed from the scope. 

Conclusion:

In general, Auckland's transport History seems to be one were we make pretty good plans but then fail completely to deliver them.

For the Rapid Transit Network, we had 65% of it in place however didn't actually start running an effective service until recently, and even then we still limit ourselves to trains every 30mins off-peak.

For our motorway network, we only managed to build 40% of it yet we have taken more than twice as long as planned to do that.

For the sections of both motorway and RTN that we haven't built, little has been done to future proof these and so we are left with significant expenses and disruption if and when we actually try to implement them.

This all comes at a rather convenient time as the Auckland Council is looking for feedback on their new 10 year plan.

It's very clear that the reason Auckland's Transport is in the shape it's in now is from under investment in the past along with inadequate vision to invest in the future. If your at all passionate about Auckland's transport I suggest you provide feedback to the council which they are engaging the public.
