We are a linear city, therefore we need cross-city roads. The provision of a primary north-south corridor is an imperative and absolute priority.
We already have cross city roads. We have a primary N-S corridor (known as South Road). The improvement of it is a high priority.
It's either an now or never situation - It will cost money, lots of it, but if we don't invest now, it'll only cost more in the future.
Most infrastructure is likely to cost more in the future than now. That doesn't mean it's a now or never situation. There's nothing that can be built now that can't be built in the future if we plan for it now. But a lot of the stuff from the MATS plan is already in the never category.
With reference to the freeway proposals of the MATS plan, we do critically need the North-South Corridor (Noarlunga and Salisbury Freeways), Modbury Freeway, Dry Creek Expressway and the Foothills Expressway. Of course not in it's exact form as proposed in 1968 - but revised to suit the conditions of today.
Not only the conditions of today, but the still valid conditions that made the MATS plan unnecessary.
Everything but the inner-city section of North-South Corridor, and the inner-city section of the Modbury Freeway is not a hard task to achieve at all.
That depends on what you mean. With a $10bn+ budget and a large tunnel boring machine it's certainly doable, but nowhere near easy!
There is sufficient land provision available for the extension of the Dry Creek Expressway (via Montague Road alignment) to Tea Tree Plaza.
It makes more sense if you look at it the other way: extending Montague Road to the Port River Expressway. It could be grade separated if necessary, but I think that deserves a lower priority.
We conquered environmental and geographical complications of the South-Eastern Freeway, the Foothills Expressway - technically the South-Eastern Freeway Extension - can be conquered also.
Firstly it wouldn't be the SE Freeway Extension, as the SE Freeway has already been extended to Glen Osmond. Secondly, there wasn't a lot of housing on the route of the SE Freeway. The same can not be said for the Foothills Expressway. And thirdly, even if a route could be found, why would you want to build it? There's not much traffic between the hills and southern suburbs. The original Foothills Expressway would've been well used because it connected with the Hills Freeway. But with that firmly consigned to the dustbin of history, why waste the money?
From Tea Tree Plaza northwards, Modbury Freeway can easily be reinstated along the McIntrye and Main North Road road corridors - with provision for the initial roads themselves.
It could be done, but the costs would greatly outweigh the benefits.
This connects to the Gawler Bypass, offering choice of route, and primary use - Northern Expressway for freight, and Modbury Freeway for all other traffic.
Once the Northern Expressway opens we will have the choice of route. The other option won't be a freeway, but there's no reason why it has to be.
The outer-suburban extremities of the North-South Corridor - Southern & Northern Expressways (and their respective extensions) are already completed/proposed for construction. Sturt Highway's duplication to the Barossa is nearly completed, and Victor Harbor Road is at some point slated for duplication and modification further down the line. These connections however are the lesser prorities to the development of Greater Adelaide's freeway network.
Considering the safety benefits they'll bring, I can't agree. But when it comes to improving Adelaide's transport infrastructure, there are more cost effective ways of doing it than with freeways.
