How about morphett road under the train line.then have diagonal road go over the train line
Leaves the station where it is

Bullshit.

There is no way that they would have built the Oaklands station, less than 5 years old, to rebuild it again.

Not to mention, they have just resleepered the Noarlunga Line through the station. Again, why all the time and effort, only to rip it up again?

Bullshit nothing. Most likely a rail overpass due to cost constraints of underpass and a road overpass is not viable due to access of businesses along Diagonal rd being basically screwed over. They'll rebuild Oaklands (embarassing to say the least - they can reuse the canapy section however and other fittings), the main problem is however that gradient the train needs to negotiate this height and fitting in a new Oaklands station (which needs to be built dead flat and not near the upwards or downwards gradient of the new line) will mean that Warradale station might also taken out.

Other news is that they are looking at a new station in the Castle Plaza area and maybe getting rid of Emerson (pretty speculative though).

Building it as an overpass would also bring the station closer to the marion precinct, both logically and physically. Pedestrians would have direct access to the precinct without needing to cross a main road.

...Buckleys buggerall! That's what they're likely to do there in the next decade. But when they eventually get round to doing something, it will be an underpass.

The new Oaklands station was designed to accommodate an underpass. And if they're sensible they'll stagger the north end so that Morphett Road Northbound traffic will cease to cross Diagonal Road southbound on the flat.

Even so, Brighton Road (Hove) should take priority.

Most likely a rail overpass due to cost constraints of underpass and a road overpass is not viable due to access of businesses along Diagonal rd being basically screwed over.

Those costs are trivial compared with the cost of raising the railway (with station) while it's in operation!

I'm guessing this may have started with someone wanting to get rid of Warradale station and thinking raising the line might be a good excuse. But there's no way it would be seriously considered.

Other news is that they are looking at a new station in the Castle Plaza area and maybe getting rid of Emerson (pretty speculative though).

What is the source of your "news"?

["Aidan"] wote

Why? Its about freeing up a poorly designed arterial road not making a new and shiny station

You might want to tell that to the business owners along that stretch. I dont think costs are ever trivial, they are usually the first thing that comes up in any conversation to do about development of any sort.

People who might know a thing or two when it comes to developing rail infrastructure. But like I said highly speculative, depends on how quickly residential component of the Castle Plaza developmentis up and going and what densities housing will end up being.

Because the Brighton Road crossing is a bigger bottleneck and would be significantly cheaper to remedy.

I didn't say they were trivial in an absolute sense, I said they were trivial compared with the enormous costs of raising a railway (with station) while keeping it in operation.

Okay believe what you want to believe Aidan, all I can say is that the most likely options on the table is what I stated before. If you have costings regarding your underpass/overpass argument for Marion Rd and a Benefit Cost analysis for whatever you think should happen at Brighton Rd forward them on to DTEI, it would probably save them a hell of alot of time and money and people would be forever thankful to you.

My thoughts on this are to build not one but two road bridges/underpasses, not necessarily at the same time either.
First would go at the Northern end of the station, and replace the existing level crossing. The second would go at the southern end of the station and carry traffic from Diagonal Road. It should be easy enough to use the two to create proper merge/join lanes between the two roads.

The two road bridges/underpasses could be built decades apart if need be.

Nonsense, the Southern end of the station goes right onto the Morphett/Diagonal connector road. Putting the station on a bridge would actually put it 9M or so higher up and hence no closer even if the station where directly over the road itself. Stairs and ramps are certainly not easier to use.

Big question at the moment is where Mike Ra... um Jane Weatherill will find the money to pay for this project. Given the Commonwealth's reluctance to pay for road projects but leaning towards rail projects instead.

And I have already explained to you why it's actually a very unlikely option.

They never seem to have appreciated anything I've told them before. But in this case I think it would be redundant anyway. Grade separation of Brighton Road is already being considered (if the Messenger is anything to go by). Marion Road was grade separated decades ago. Morphett/Diagonal Road will get an underpass - it's just a question of when.

The northern end of Oaklands station is in a residential area, well away from any major road. Both roads are at the southern end of the station, and the station was designed to be compatible with the future construction of an underpass.

Don't you understand? There will never be a need for an overpass as well as an underpass. The former would be noisy and unsightly, but most of all pointless, as traffic lights can easily handle the volume of traffic where Morphett and Diagonal Roads converge and diverge. And building a long overpass just to replace two sets of traffic lights might make sense on South Road, but it wouldn't make sense here!

I seriously doubt that you have better connections than I do about this matter. Planning study being undertaken, everything is on the table, cost IS a major consideration. At this stage overpass s most likely but there are ramifiactions. End of story.

Putting a bridge over the rail line makes the most sense to me. Would have to be the cheapest, quickest and most logical option.

I think that politics will play a very big role here. The government will not be too keen on ripping up the brand new station due to the potential for embarrassment.

And yet, that's exactly what Pat Conlon said was going to happen.
