News & Discussion: O-Bahn

[The Scooter Guy]

Unfortunately, the O-Bahn opening plaque got torn off by vandals
But I found a picture of it from the early 90s perhaps...

[Waewick]

just out of interest....have we heard anything more on this?

or was it just a beat up?

[AtD]

Re-read page one. It answers your question.

$61.0 million over four years

[Waewick]

Construction is expected to commence before the end of the year.

?

has anything started?

[rogue]

A tender has gone out for construction a new 2 lane bridge over the Torrens at Hackney Road.

The new bridge will be built to the west of the existing bridges. North bound traffic will travel via the new bridge once complete and south bound will travel via the current north bound bridge. O-bahn and other bus services will then have a dedicated corridor using the current south bound bridge.

I'm not sure if 2 new lanes will be built to the immediate west of the current alignment all the way to North Terrace.

[AtD]

To the west? That's parklands.

Brave.

The way I read that is that there will be a two-lane two-way bus only corridor along the eastern side of Hackney Rd. I'm sure the property owners along Hackney Rd would have something to say about that!

Wouldn't that also mean that the north bound buses would have to cross the 2 south bound traffic lanes in order to get to on to the track? Or perhaps they're maybe looking at closing the tunnel and realigning the track entrance so that it's on the eastern side of Mann Rd?

[Westside]

Would the bridge under Park Tce where North-bound buses enter the o-bahn be wide enough for both tracks?
Also, given the service lane to the east of Hackney Rd and the parking to the west, I doubt there would be a great deal of parklands aquired. However, one or both would have to go.
I did note that originally, only one lane was to be provided down Hackney rd - (ah la Southern expressway style) - has this changed?

the bridge under Park Tce

as opposed to the Park Tce subway over th O'Bahn route ...

Nope. It's only wide enough for one bus width.

Did you know that the French for 'bridge', 'pont', can also mean a connecting tunnel in a subway, when prefixed with the French for 'small', 'petite'.
So now when you're in Paris struggling to work out how to connect from one line to another without incurring another fare, you'll know what 'petite pont' on the Metro map means.

No need to thank me...

i believe "bridge" is masculine in french, so it's "petit pont" (drop the 'e'). Probably still applies even though we're talking about a tunnel. Oh, and french for O'bahn is O'bahn (but said with an outrageous accent)

Pas besoin de me remercier...

Tips and rumours
We haven't heard much about the much heralded extension of the Adelaide O-bahn, from its current entry north-east of the city all the way through the city to Light Square, since late 2009. Surprising really, since the extension would greatly speed up the trip from the termination point to the U1 stop on Grenfell Street, which can double the current time taken for the trip from Golden Grove. Be a bit of a vote winner you would think.

Alas, no, because it has already been dumped by the state government, but as there are some very marginal seats north-east of Adelaide no one is admitting it. Turns out the Adelaide City Council weren't too hot on it, so they built pedestrian safety traffic islands up Grenfell Street on the intended route (part of their ongoing development feud with SA government?).

Neither where the influential "save the parklands" groups who were plenty unhappy that the route was going to cut through green areas of the eastern parklands.

The word is that the STP groups have already been told that the state government have dropped the idea.

I was suspecting the Govt has been quiet on this because removing lanes from Grenfell and Currie Streets would be an easy point of attack for the Libs. I hope I'm right and the above tipster is wrong.

[Waewick]

if this doesn't get brought up by the Libs I would be amazed.

whilst it was the Feds who put the deal on the board from what i understand surely a backflip like this gets some attention?

I wonder what happens to the funds allotcated to the job? can the state move it elsewhere?

[muzzamo]

TBH i would be very surprised if the State Government let themselves be pushed around by the parklands mob and council on this one.
