A rail underpass wouldn't work because... the NS Motorway Tunnels will be in the way!

Well I got the pass right. If a rail overpass can be built, then it will suffice. There is a slim possibility of routing the rail underneath the underpass, taking into account the wires. This will require significant $ though. Are there any actual drafts/plans which indicate what is to be done?

I'm sure that the Elder Smith Rd overpass has wires at a reduced height, which does not cause any obvious issues.

I'm pretty sure tunnels are being positioned in a way that will still allow for a rail underpass at Cross Rd to be constructed one day in the future.

Correct, that was the plan in the previous design and is most likely included in this one as well.

There should be space for a rail underpass below Cross Road and above the North South Motorway tunnels. The new motorway tunnels will still be fairly deep below ground at that location and the rail underpass would only need to be an excavated cut and cover construction.

Delivered to letterboxes today (I'm in Wayville). Phoros aren't great, but you get the gist. The new CRG will be interesting. Feel free to click on images for larger view.

Did you capture these images using a flash? They are unreadable near the centre of some images.

Does anyone know if Jarvis Toyota are relocating to a new site?

How about be grateful that ChillyPhilly kindly took these pics.......

I notice in one of the pages posted above, they mention the southern tunnel portal will move by 300m to the north.

I assume that they mean the tunnel will be 300m shorter?

I did, and was in a hurry - apologies! The flash was needed. I'll see if I can find another copy.

I interpreted it that way. Mr Koutsantonis likes the trench through part of his electorate, and wants to share the enjoyment with more of his southern neighbours.

Here is the second page, which the flash eliminated partly.

Admittedly I haven't delved too far into the info that was released last week so apologies if this is answered there, but what is the rational behind the Southern section being a tunnel rather than a trench?

The section of South Rd between Darlington and Castle Plaza is quite similar to the areas around the T2T and R2P prior to them being upgraded. Mostly retail and light industry along the corridor, with residential behind. If a trench was deemed suitable through T2T and R2P, why isn't a similar solution being built north from Darlington?

Is the volume of traffic too high that construction of a trench wouldn't be possible? Is there contaminated soil? Some other factor at play?

Or is it just that the impacts of a trench on the urban area have been deemed to be too high, with a tunnel being the better solution?
