Would it be possible that they plan to go overhead and not buy any more (or at least at lot less) existing properties on South Rd?
If they went up overhead from say the brickworks to down before the Gallipoli underpass and then up again after the Tram bridge all the way to the Tonsley/Ayliffes Rd underpass, could it work?
Further it would be done over largely commercial areas similar to the Grand Junction Rd/overhead expressway.
Similarly if they went over (or even under) Regency Rd (& just block off either side of Pym St), would it not mean the whole 80km of South Rd is finished as a non-stop freeway/motorway?

The area thru mile end thebabarton is heavily populated and an elevated road in this vicinity would not only be an eyesore, but also create noise problems over a wide area given adelaides flat terrain. A sound shel would need to cover most of the route. Similar situation thru Black Forest.

What was the reasoning for going up for the superway section?
I imagine going down you might have issues with ground water level and general flooding being so close to the ocean with almost zero elevation.
I imagine that might also be why the plan is to go over the Torrens river.

most likely soil contamination

I also believe it was the avoid disrupting rail freight services through the area, which is also why it was built so high...If double-stacked rail freight becomes a thing they'd need to have a road elevated at-least two shipping containers worth above.

There is already double stacked rail freight in Adelaide.

I dont think double stacked containers go to Port Adelaide

All talk - no action

Have to agree there. Plenty of kyboshing of everything, but no actual alternatives put up. Does he have a vision for Adelaide/SA besides closing down the pokies?

Just a random thought, will all of the complete North-South Corridor consist of trenches and elevated roads? Or will/can there be segments where the Corridor can be the surface road, and other major roads just be deviated beneath it?

Surface road is used for access to existing buildings and roads.
Where is any decent stretch of south Rd that isn't lined with existing businesses and roads?
The freeway must be run at a different level to the existing south Rd, it is just the only practical way.

Section 7.1 of the North–South Corridor The 10 year Strategy (Available here: http://www.infrastructure.sa.gov.au/nsc ... y_strategy) talks about minimising redundancy when constructing each section (ie: there isn't much point building a section of road for it to then be ripped up in 3 years time when the next section of the corridor is constructed.) My understanding is that this reasoning is why the duplication of the SEXY was completed when it was. Duplicating it after upgrading Darlington would have resulted in portions of the Darlington upgrade being made redundant. Hence, the SEXY was duplicated before Darlington was upgraded.

The report has three guiding principles to minimise redundancy:
- Project section to start and finish at grade;
- Elevated structures to be delivered in one section;
- Tunnels or lowered road to be delivered in one section.



Using these principles, I would say that it is highly likely that some sections of the North South Corridor will be at the level of the present day Road.

Where I foresee this changing is where on/off ramps are to be constructed, ie: Road section is delivered, with temporary ramp used. 5 years later, on/off ramps constructed, traffic diverted to on/off ramps, temporary ramp removed, elevated/trenched road now flows below/above grade into new section. Whether this is feasible and if the extra costs are worthwhile is something that would need to be looked at..

How will they do the section from the Torrens heading south?
The road is 7 lanes wide at the corner of South / Ashwin with no room to widen, do you think the section from the Torrens to Anzac Highway will only be two lanes in each direction.
Maybe a tunnel two lanes in each direction from Brickworks to James Congdon? The third lane will feed onto the surface road, so three lanes, two into tunnel third onto South Road (which will split into two) from after Torrens until just after James Condon.
