NZTA have put some interesting images up on their website of the proposed Christchurch Southern Motorway stage two junctions, overbridges and underpasses. Some of the more interesting ones:
Junction between CSM2 and four-laned SH1
Weedons interchange on four-laned SH1
Waterholes underpass on CSM2, looking towards Christchurch and Port Hills
Shands interchange on CSM2
You can see the rest here. I don’t generally have too many problems with these projects and this is really just a post for interests sake. It does make me roll my eyes a bit though when you consider they are spending almost $1 billion on the various Christchurch RoNS projects and no one bats an eyelid (except those in Prebbleton who claim it ruins their ‘rural’ lifestyle) yet all the critters come crawling out of every dark hole to have a rant about the ‘wasted’ money proposed to be spent on developing a world-class public transport system for Christchurch. We need a more balanced approach, but I am already worried more motorways are being lined up for beyond 2020 (and that really worked for Auckland). In the meantime though, enjoy the images!

Is it even proper ‘motorway’ (ie no cyclists)? My understanding is that it will have wide shoulders to ‘accomodate cyclists’. At this cost they should build a seperate cycleway, similar to what was done with Sydney M7.

From Templeton to Rolleston it won’t be full motorway status as it will essentially be just a widened and upgraded SH1 (so really expressway standard I guess). The section currently being built, and the planned stage two to Templeton, will have full motorway status and will have separate cycleways built, as far as I understand.

Confirmed… The “new” road will indeed be Motorway – The remainder section of widened existing road will be Expressway though it isn’t decided whether it will be labelled as an Expressway like the Expressways in Tauranga and Waikato are.

I do wonder whether they investigated tolls to pay for it, what would people in chch be prepared to pay? Possible all the superfund to build it rather than investing overseas
