News & Discussion: O-Bahn

Why doesn't the council or Westfield pay for it given it will get the benefit.

Sensible and something I agree with, but is it necessary? It's literally less than a minute's walk from the interchange to the entrance of TTP.

Considering I was quoted in that article without asking if they could quote me.. People seem to be focusing on distance, and rain.
My suggestion had nothing to do with that.

There are a number of key points

- The park 'n ride, is already full and they have now closed the old park. The interchange itself is a perfect location to have parks built on top, just like the bus station in the CBD.

- There has been talk many times about a second food court at TTP. Anyone that goes to the food court on a weekend knows how hard it is to get a table. Food on top of the interchange would be perfect.

- Adding apartments on top maybe targeted at elderly living would provide more customers to the shops, along with direct access for those living there to the CBD. I'm sure many older couples would like medium rise living, but out of the CBD with easy bus access.

- Small Coffee shops "stall" style in the middle of the interchange would be perfect for people grabbing something on their way through. They could also sell tickets rather than wasting time when the bus turns up. Weekdays is not too bad. But on weekends few people have metrocards, causing huge delays.

- An enclosed bus interchange would make people feel more secure. 24/7 security, better seating and facilities. It would be more like the CBD train station.

- An enclosed interchange could force people to exit through an upstairs area with links to car parking, TTP, and back streets. This would make it safer as people wouldn't need to, or be able to cross the path of the buses.


None of this was a government funded idea. It should be funded by a mutual group of invested parties with a government body bringing the groups together to ensure the outcome is beneficial for all involved. Groups would be Westfield, developers and businesses wanting to rent space.

Some pictures from Sunday 14 Aug 16. (1) work on the Tunnel walls looking south West from Dequetiville Tce back to Rundle Rd. There are some other service pipes being temporally supported. (2) the retaining walls leading to the tunnel entrance off Grenell St definitely rise up above the existing ground level.

[how good is he]

Pretty shocked just how high the retaining walls are above ground (3m or more at peak) for a tunnel. Looking forward to see how they will landscape to cover it. Maybe a green plant wall along it?

[PeFe]

Yes a green wall......before it is "tagged" with spray can scribble

I was the same, I really expect the entrance to be close to Grenfell street too.

I'm hoping they have something planned to make it less obvious.

There is a lot of 'saved dirt' in heaps close to the site, both at the Grenfell St end and near Dequetivlle Tce.

[SBD]

I have not seen the stockpile of dirt that was where the tunnel is going to be. It stands to reason there will be dirt left over that has to go somewhere, although it may not all be good topsoil. Also, from a stormwater management perspective, the "approach roads" to the tunnel probably needs to slope away from the tunnel to prevent a sudden downpour from filling the tunnel faster than pumps and deep drains can get the water out again. Grenfell Street is higher than the park, so there has to be some interesting engineering to get the levels right so that the tunnel does not become the direct route for rain falling in Grenfell Street to find its way to the Torrens, even if one or two drains are blocked somewhere. Hopefully by the time it is finished, the road will look like it is entering the side of an attractive low hill. I think we (the public) have only seen marketing artist's impressions, not engineering and architectural drawings.

Drone's Eye View:

The Sunday Mail contracted a licensed drone operator to capture images of the $160 million construction project from the air.
The aerial photographs reveal the magnitude of the project. Tunnel works began in April, and at the end of the month construction workers will begin placing a “lid” over the tunnel, made of large concrete slabs.
It will later be covered by grass and other plants, returning much of the area to parklands.
Workers will also have to fit out the inside of the tunnel by installing lighting and electrical connections.
The dirt dug out to clear the tunnel will later be used to backfill gaps and cover the concrete lid before landscaping can take place.
The whole project is expected to be complete by the end of next year.
The State Government says the 650m bus tunnel, from Hackney Rd to East Tce, will reduce daily bus commute times by an average seven minutes.
The construction works create a tunnel through Rymill Park to connect the bus route to Grenfell St.
The dedicated bus tunnel begins adjacent the National Wine Centre and emerges at East Tce, near Grenfell St.
The Transport and Infrastructure Department is working with the Adelaide City Council on plans for steel art structures and landscaping at the entry points to the tunnel.
A department spokesman said it was preparing to release more detailed concept images in about a month, after further approvals from the Development Assessment Commission. Residents and community and business leaders had campaigned strongly against the project, arguing it would “butcher” the parklands.
The Rymill Park Alliance — a collection of 12 community groups — was formed to lobby the Government to scrap or amend the project.
More than 1000 protested in Rymill Park in June last year. The backlash prompted the Government to revise its plans.
More than 31,000 people use the O-Bahn on weekdays and commuters make more than eight million journeys on the route each year.
Transport Minister Stephen Mullighan has previously said that realigning Rundle Rd to connect with Grenfell St would give the Government the “flexibility to talk in the future” about extending a tramline to the eastern suburbs along the old tram corridor through Rymill Park.

wow That is progress right there!

Cut n cover was a good choice to speed up the build process, meaning the parklands should be back to greenery sooner than later.

No one seems to have posted about this yet, but the new section of East Terrace has now opened and the old section has been fenced off. It makes a lot more sense being this way, however turning onto the new section from either Bartels Road or Pirie Street makes for a relatively uncomfortable experience but the approach to the Grenfell Street intersection is quite pleasant.

[Torrens_5022]

How did they realign it - I haven't been in that part of the city for a while. Does it form a realigned T intersection at Grenfell / East and Easr Tce flows down to the Pirie St intersection, removing that park area next to the old substation.

The following from late July is an interesting watch and not only for the construction footage.
