[U/C] M2 North-South Motorway

For the 2 or 3 years in between finishing T2T and starting the next bit? I don't know, maybe it will eventually go back to 2 lanes in each direction with a pylon in the middle of the bridge?

Maybe there will not be a non freeway south road between Hindmarsh Ave and Ashwin Parade?
South road does stop under the Superway for example.

So you have the motorway as 3 lanes each direction over Torrens at ground level.
South Road might not start again until Ashley Street.

Squeeze a 2 way service road on the east side of freeway just south of Torrens River. Or you could likely make access via Ware Street behind.
Squeeze a north bound onramp from Ashwin Parade but I do not recall Ashwin being an entry point.
Have freeway go under Ashwin Parade intersection for the next trench/tunnel section.

From West Thebarton Hotel heading south on east or west side I assume 1 side will have land acquired, I actually assume it is the east side that would go.

South Road at the Ashwin Street corner at Bricksworks is eight lanes wide, another two can easily fit if you build the road up to Brickworks wall, plus just south of the river the old Brickworks buildings start an extra 20m further away from the road. A tunnel portal could be built here and it would surface around James Congdon drive. If they want to build a 3 x 3 lane freeway and a 2 x 2 surface road tunnelling is really the only option, theres not enough room for a 6 lane raised freeway through Torrensville / Thebarton / Mile End on top of South Road, the road is only 2 lanes wide, and some houses are only 3m from the road.

I don't think any grade separation of South Road is needed until the Henley Beach Road tunnel. With land acquisition, they can make it much like the southbound lanes of the southern end of the superway - 3 freeway grade lanes, with a concrete barrier and then 1 or 2 surface lanes on the other side.

Send Ashwin Parade under South Road with connections to the surface road only.

For George street, start trenching South Road,ready for the tunnel under HBR and have George go over.

I agree. I don't see the perceived need for the motorway to be either above or below ground in every location. The merit a trench has, however, is it reduces visual impact in residential areas and crossings are easier.

South of Ashwin Parade is a highly residential area, much of it consisting of character/heritage properties with nice leafy streets. Why should these inner west residents have to suffer huge chunks of their suburbs being acquisitioned so they can live next to a 10 lane surface freeway for the rest of their lives? How do they go about crossing it for a start? It's not an acceptable road design in a residential area - hence the lowered motorway around Croydon, Brompton etc - the impact to existing residents is much lower.

I agree with this, even still I think a tunnel would be much better for this area, much more costly but surely they could put out for at-least one section of this roadway.

So they're too elitist now to have to suffer the inconvenience of a non stop motorway?
Maybe they don't need easy access to on/off ramps to the motorway either then?
At the end of the day they live along or near the main north-south route for metropolitan Adelaide. Too fucking bad if properties get compulsorily acquired by the government to make way for better transport infrastructure that benefits the whole damn city. I knew when I was ten that south road needed a major upgrade, what's these peoples excuse?

Typical Adelaide attitude. I don't want that in my area blah blah wah wah wah.
Sadly we have governments that are chicken shit, and pander to noisy minority groups.
This is infrastructure that should have been built 30-50 years ago.

If Labor gets back in, it'll get done.
If Liberals get in, work will stop, or it'll be botched in another one way motorway example.
If Xenophon gets in, he'd probably cave and build them the worlds most expensive tunnel and gets dressed up as a tunnel boring machine for the opening.

Settle down their Rev, the discussion's not about whether it should be built, just whether a trench or a tunnel is the best way to go, given the nature of the area....

The nature of the area is that they live on a major north south artery. Their opinions should be sympathized with, and then ignored.

Well we're doing trench for Torrens to Torrens and Darlington + raised motorway for the Superway. I doubt a long section of surface-level freeway is on the cards anyway. Trench is the way to go I reckon.

The main consideration should be cost to acquire needed land and ability to save state and national heritage listed properties.
In the 60's it was announced there would need to be a freeway cut through this area. 60 years later it is actually being built, how much more notice did the residents need?

There will be a 10 lane road built through the area and residents need to embrace that.

[Llessur2002]

I'm not in any way saying that the road should not be upgraded - I live in Croydon and am very happy with the outcome of the T2T project. A trench was the right solution for the area given that it is largely residential and heritage.

Just because Adelaide needs a decent north-south freeway, why shouldn't it be done in a way that minimises impact to people's quality of life? We shouldn't destroy our residential communities just for the sake of progress -T2T has proven that the two can go hand in hand very successfully.

A trench or, even better, a tunnel would be the best outcome for this area - and I suspect what we end up with, which will be a good outcome for all.
