The estuary is saline but not navigable, the gorge is too steep, and the transport infrastructure for a city up in the hills would be much more expensive.

Seaford rail extension over the Onkaparinga River, in Adelaide's south, on target
Work is on target to complete one of Australia's longest rail bridges within a year.
South Australian Premier Mike Rann inspected the Seaford rail extension today which includes the 1.2km bridge over the Onkaparinga River, in Adelaide's south.
It features 21 spans placed 53 metres apart, making it longer than the Sydney Harbour Bridge.
"The concrete piers for the bridge range in height from 22 metres at the northern end to 13 metres at the southern end, providing an average bridge height around that of a six-storey building," Mr Rann said.
The bridge is part of the $291 million rail extension project which is included in the SA Government's plan to spend $2 billion upgrading public transport
No They Haven't. I was down having a look this morning and there's been no movement on that.Tonsley213 wrote:Have they moved any beams out yet?
today [18 Oct 2011] sees the first span from the northern side slide out over River Road from 9am.
Drove past and had a look this evening (19th), and the span has moved, the Steel "nose" attached to the span is now just overhanging River road. It's got a long way to go to reach the first Peir.fabricator wrote:As posted by a construction worker on another forum:

Pushing bridge spans forward in this form is very slow, to the naked eye you'd never be able to see it moving unless you're standing right up next to the structure. Push too quickly and there's potential to topple the piers due to the momentum.Archer wrote:Drove past and had a look this evening (19th), and the span has moved, the Steel "nose" attached to the span is now just overhanging River road.

Wonder if it stopped there due to problems or if it is a process that's so slow that it will actually take a week to complete?
