[U/C] M2 North-South Motorway

[rogue]

According to the early info available, T2D project volumes:
Quarry materials 2,000,000t
Concrete 760,000m3
Asphalt 470,000t
Precast tunnel segments 55,000 (7,000 to be made before tunnel boring starts)
Spoil produced 8,000,000t

Speaking of the north, it'd also be good to have the spoil used for the embankment alongside the Northern Connector for the future rail line.

A transport bureaucrat has suggested building a sky freeway instead of a South Road tunnel in an Advertiser article I am unable to upload.

I am sure sky rail works but a sky freeway?......What happens if there is a major accident? How do you clear the road????

[greenknight]

The same way they do at South Road Superway. Exactly the same principles.

[PeFe]

The Super Way is 2.8 kms....I think this proposal looks more like 10 kms...

It's a no from me. Visual impact would be too great for too little return socially and economically.

Big yes to a massive sky rail proposal! This would be of greater benefit.

Oh good god no, sky freeways should never be a thing. You only have to look at the US cities to see how horrendous they look and how divisive they are.

[noted]

Yep, my thoughts went straight to those ugly US 'sky' freeways as well. Well worth paying the extra money to avoid that eyesore.

Its actually a former senior transport department bureaucrat.
Pretty detailed render for a former staff member..

I like how the render shows perfect grass and trees.
Too bad the reality would be dirt and poorly maintained trees.

[Nort]

Yeah heck no.

The raised road worked well for the section between Regency and Salisbury Highway because it's primarily industrial, completely different context here.

First it was Rod Hook's Cable Cars, now it's Luigi Rossi's Sky Freeway... Do all retired department leaders make their own businesses and propose out-there ideas to leave a name for themselves?

[Saltwater]

Lord no for a skyway. The 60's called and want their transport planning back. Just look around the world and cities are furiously trying to tear down elevated motorways that were put up in the 60's and 70's. Boston did the Big Dig, Sydney is tunnelling from Drummoyne to the Northern Beaches, anyone that's walked around Bangkok understands how hideous the elevated motorways are there (granted they didn't have many choices with the rain and geology), and meanwhile Adelaide is talking about ditching plans for tunnels and replacing them with... an elevated motorway.

[Mr Messy]

DIT put out something which says they seriously considered building an elevated motorway like the superway, but they amount of extra land required was immense.
I think they're too far down the tunnel route to change to an elevated road based on a jpeg

Also the width of south road in the render is overly wide and the elevated road is super narrow

While on the subject of changing the format (yet again), what are the chances of a change of government in SA, and if so, what is the chance that a new Labor government would scrap the whole tunnel plan as overkill and go back to their preferred option of hybrid short tunnels and trench?

[[Shuz]]

I think it would political suicide for Labor to change tack again. The momentum is firmly in favour of the full length tunnels, and despite the objections of a few disgruntled residents along the corridor, I think the vast majority of people just want to see this project done already. It was supposed to be done 50 years ago. The time is well and truly overdue. The DIT bureaucracy would probably kick up a storm also if they had to go back to square one again.
