Just as an aside - those images are taken from an airplane. Satellite imagery available to non-CIA/Military types have a max resolution of about one pixel = 5 to 15 metres depending on which satellite you have access to.mawsonguy wrote:The satellite photographs...
Yeah but surely they can turn those grainy images into an HD picture of someone's face by getting a nerdy type in glasses to repeatedly press a button that says 'enhance' like they do in those movies?monotonehell wrote:Just as an aside - those images are taken from an airplane.

The method used on the Bakewell & Gallipoli underpasses was to build sections of the walls from the top down as excavation proceeded, securing them with soil nails:mawsonguy wrote:The satellite photographs as at 9 Feb 2016 clearly shows a reinforced concrete "strip" being built between the northbound surface road and where the lowered roadway will eventually be constructed. A photograph in the latest Construction Newsletter has a photo showing this construction as "Top of the wall barrier". Not being an engineer, I just wonder how you can buid the top of a wall without first building the bottom of the wall! I thought it may be a barrier wall set back from the cutting retaining wall but the visualisations don't show that rather they show one continuous wall from the bottom of the cutting to the top of the barrier. I also thought it might be the gutter but the satellite photo shows capping not a gutter. Anyone with better knowledge of what is actually going on?

I was looking over the long term outlines for the N-S corridor and I was wondering what the provisions are (if any) are for on/off ramps in the vicinity of the inner CBD loop? Anyone seen anything about this?
That's not the way that I read it. At page 21 it refers to the:Torrens_5022 wrote:There will be an interchange at Port / Grange Rds and the next is James Congdon Drive, page 21 http://www.infrastructure.sa.gov.au/__d ... rategy.pdf
and then at page 42:Sir Donald Bradman Drive and James Congdon Drive Interchange
So it appears that traffic getting on and off the southern portion does so at James Congdon and traffic getting on and off the northern portion does so at Sir Donald Bradman. If you are coming from the north and want to get off to go to the CBD you do so at Port/Grange Road or the next inerchange which will be Sir Donald Bradman. Given that James Congdon feeds onto Sir Donald Bradman Drive, that should make for a good traffic jam.... the split diamond interchange of James Congdon Drive and Sir Donald Bradman Drive.
Not quite, the movements are quite restricted at that intersection.mawsonguy wrote:So it appears that traffic getting on and off the southern portion does so at James Congdon and traffic getting on and off the northern portion does so at Sir Donald Bradman.

Such as no left turn onto Don Bradman Drive from James Congdon.Norman wrote:Not quite, the movements are quite restricted at that intersection.mawsonguy wrote:So it appears that traffic getting on and off the southern portion does so at James Congdon and traffic getting on and off the northern portion does so at Sir Donald Bradman.

And also no right turn from JCD to SDBD if you're heading north-east.alexczarn wrote:Such as no left turn onto Don Bradman Drive from James Congdon.Norman wrote:Not quite, the movements are quite restricted at that intersection.mawsonguy wrote:So it appears that traffic getting on and off the southern portion does so at James Congdon and traffic getting on and off the northern portion does so at Sir Donald Bradman.

Hence my Richmond Road concept, but looks like DPTI has decided its SDBD or nothingChillyPhilly wrote:I'd expect a fairly significant interchange to allow good airport access.
Got an image of that that you can send?fifty wrote:Hence my Richmond Road concept, but looks like DPTI has decided its SDBD or nothingChillyPhilly wrote:I'd expect a fairly significant interchange to allow good airport access.

The point I was making is that traffic which currently comes off South Road to go to the CBD at Richmond Road, Sir Donald Bradman Drive and Henley Beach Road will all get pushed onto Sir Donald Bradman Drive once the freeway is contructed. Given that many people who currently use other routes to access the CBD will use the freeway instead, I can see a four fold increase in the traffic on SDBD west of JCD. Current traffic restrictions at the SDBD and JCD intersection will have to be altered.Norman wrote:Not quite, the movements are quite restricted at that intersection.mawsonguy wrote:So it appears that traffic getting on and off the southern portion does so at James Congdon and traffic getting on and off the northern portion does so at Sir Donald Bradman.
