Redoubt Road-Mill Road project causing angst

A fairly significant proposed roading project, from Redoubt Road in Manukau down to Mill Road in Takanini, has pretty much slipped by unnoticed as its investigation continues – although some elements of the project seem to be causing quite a bit of angst with the locals. This in the NZ Herald today:

Hundreds of homes are in the firing line of a new arterial road for South Auckland – of which the first section alone is costed at almost $250 million.

Auckland Transport says about 260 properties, many of them along Redoubt Rd above Manukau, are in the path of the first stage of what it ultimately envisages as a 32km eastern bypass of the Southern Motorway to Drury.

The council organisation revealed last night a cost estimate of $246 million for the 9.2km section from Manukau and Flat Bush to Alfriston east of Manurewa, parallel with Mill Rd – including $66 million for property purchases – although it has yet to hazard a price for the full project.

Only $82 million is allocated for the next 10 years, and the project could take twice that time to complete.

But it intends seeking a route designation for the first section from the council’s planners by the end of next month, and says it is powerless to stop landowners from building new homes until then.

The plan has horrified residents of the historic Redoubt Ridge, through which Auckland Transport intends carving a road corridor up to 30m wide, past a remodelled junction with a widened Murphys Rd running from Flat Bush.

At a high level there seems to be some logic in the project – providing an eastern alternative to the Southern Motorway, as shown in the Auckland Plan transport project map:aucklandplan-millroadHowever, as always a lot comes down to the details of project like these – particularly in terms of what kind of corridor upgrade we’re going to get for the massive quarter of a billion dollars proposed. Checking out the proposed cross-sections on Auckland Transport’s website I can’t say I’m particularly impressed as what’s proposed looks like a defacto motorway with no provision for public transport, rather than a true multi-modal corridor which will support high quality development around it in the future. For example:2-alexia-murphysA proposed cross-section of Murphys Road, which connects the corridor with Flat Bush, is even more bizarre:murphys-cross-sectionWhat on earth is the point of wasting 8.2 metres of road width with a giant median strip? It’s not like this road is going to be upgraded to four lanes each way at some point in the future utilising the median strip (at least I hope not). The impact of the road on the bush in this section is highlighted in the Herald article as one area that’s annoying the locals:

Redoubt Rd resident Raewyn Roberts, spokeswoman for an action committee to fight the proposal, yesterday called on Auckland Transport to avoid destroying what remained of a valuable ecological corridor from Murphys Bush to Totara Park and beyond.

Ms Roberts points to the design of the project as a “massive dual carriageway”:

“It’s appalling,” she said. “This is a mega, mega project – they have this massive dual carriageway which will come roaring up from the old Manukau City centre, wipe out the ridge, then sweep down Mill Rd.”

While a certain amount of “moaning locals” seems inevitable with most transport projects I think what’s horrifying people most of all in terms of this project is the vast over-design we’re seeing. A southern motorway bypass needs to be effective at shifting quite a lot of traffic, yes, but whether it needs to be designed for 80 kph average speeds (which is what the design looks like) with enormously wide medians is quite another matter. I think a scaled back project would not only be more likely to gain public acceptance, but it might also cost a hell of a lot less than the $250 million the current monstrosity is budgeted to cost.
