[U/C] M2 North-South Motorway

[ChillyPhilly]

The most recent design included space for a rail line to the west of the road, the middle of the road design was removed a long time ago.

Correct, the rail component was to be built on an embankment adjacent to the road. I might be wrong but I think the embankment is already constructed in parts.

It would have connected to existing rail going west to the Le Fevre Peninsula and heading north to Virginia.

I assume with all this expertise we will be gaining over this project, we will have plans to continue to utilise it in other projects post 2031?

Seems a waste if not. I mean apart from the finished product of course

The tunnel boring machines should have been here 3 years ago. labour has spent the last 3 years evaluating the libleral project costings

Interesting considering Labor has been in power for only two of those years.

I think he means with the change in government from Labor to Liberal back to Labor and each government looking at plans and drawing up their own.
If we hadn't had Liberals come in, chances are this project would have been well underway a couple of years earlier.

The Weatherill Labor plan didn't need TBMs. The section past Castle Plaza was going to be elevated like the Superway north of Regency Road. The section near Henley Beach Road and Sir Donald Bradman Drive was to include two short cut and cover tunnels. The tram bridge was wide enough for that version.

Precisely. A lot of Labor's approach for this corridor was, in my opinion, low cost and not the best outcomes. Which I get they were sticking to a budget, but Labor typically spend a lot when in government, and the improvements required for this corridor are a once in a generation investment.

The way I view it:

- The Northern Connector is the best project outcome delivered so far on along the North-South corridor.
- The Superway was over engineered and for the time a significant over investment.
- Gallipoli underpass always seemed to be a short-term fix until a broader plan came to fruition.
- The Glenelg tram overpass considered future planning but felt like it was a rushed project.
- Pymm Street to Regency Road is probably the next best stretch of this corridor in terms of the final product.
- Darlington is also a good stretch of road (I attribute this the sloped walls allowing more natural light into the roadway) but the road surface is somewhat of a rollercoaster.
- Northern expressway felt like it was done on the cheap and perhaps this is something that they will revisit with urban sprawl.
- Duplication of the Southern Expressway did the job it needed to.
- Torrens to Torrens is probably the worst stretch of road, similar to Darlington the cost cutting has meant it's a roller coast surface, the remediation of the surrounding area was poor, the one entry/exit on this section for Port Road, is chaotic, and unlike Darlington, you feel like the walls are closing in on you.

Some of my points might seem more related to aesthetic but I figure, if we're going to wedge a freeway through any suburban area, a certain level of care needs to be applied in the final product, just the same as for functionality, doing things on the cheap for a project that will likely only be done once isn't acceptable.

In hindsight, I think they've done the best they can in a shitty situation.
Constrained by trying to basically trying to retro-fit a freeway in a built up urban environment while trying to mitigate community displacement given South Australian's still seem to remember MATS and the scaremongering (rightly or wrongly), as well as budget constraints with the political pressures of not putting the state in significant debt.

Stop planing and start digging . Adelaide most be the most overplaned and underdeveloped City in Australia.

I'd rather that than the shitshow in Sydney with the Rozelle Interchange along the private partnerships that push infrastructure projects along at breakneck speeds which end up costing residents mega bucks to use.

What's worse? Congestion and wasted time, or having to pay heavy tolls to a greedy foreign corporation in order to drive across the city? I'd say it's the latter, just. I think the worst thing about tolls is that they are effectively regressive taxes. Better-off people can not only better afford tolls, but they're likelier to live close enough to work so they don't need to use toll roads (or likelier to work from home).

Will these tunnel-boring machines be entombed permanently in the ground once their job is done or will they be taken away in this instance?

A smart forward thinking government would plan ahead and repurpose them for the following projects which will also require tunnelling;

- Underground CBD Rail
- Mount Barker Rail
- East West Link

Unfortunately we're in short supply of smart forward thinking politicians.

Love to see the R1 ring road and short south added to that list.

Not sure how long these things last. Be boring continuously for 20+ yrs which would be fun.

Short South / East West Link are the same thing.
