Stage 2 of the Augusta Highway redevelopment means that between Adelaide and Port Augusta, the only town you will travel through will be Port Wakefield.

Have they announced an actual scope for this? I know it included duplication from Port Wakefield to Lochiel, but will Lochiel be bypassed?

It still leaves Warnertown on the highway between Wakefield and Augusta

I am assuming that Lochiel will be bypassed, but possibly between the town and Lake Bumbunga, in much the same way as Lower Light is bypassed (i.e. the town is on a service road alongside the highway). And I had forgotten about Warnertown, sorry.

Anyway, I seem to have hijacked the thread ...

SA allocated only two-thirds of promised $3.2bn for major road projects in Federal Budget

SA was promised $3.2bn in major road project funding. Just two-thirds of it is actually in the Federal Budget – and only $130m this year.

Government commits further $15b national infrastructure programs
Treasurer Josh Frydenberg has announced a further $15 billion in additional infrastructure commitments will be added to the government's 10-year, $110 billion national…
Only two-thirds of South Australia’s promised $3.2bn for major infrastructure projects, including the next part of the North-South Corridor, has been allocated over the next four years in the Federal Budget.

And just $130.8m is allocated in the 2021/22 budget.

Budget papers reveal $2.1bn of the pledged cash splash has been earmarked within the Federal Government’s forward estimates, which take in the next financial year to 2024/25, inclusive.

It is unclear when the remaining $1.1bn will be handed over.

Overall, SA has been promised $10.7bn for transport infrastructure, from smaller local road upgrades to nationally significant thoroughfare projects, over the coming years.

The budget papers also show the bulk of the $3.2bn in major infrastructure funding is not set to start flowing through until 2023/24.

In 2021/22, only $130.8m will be paid out while $341.6m has been allocated for 2022/23.

In the following two years, $823.6m and $807m will be distributed, respectively.

The importance of the North-South Corridor was highlighted in Treasurer Josh Frydenberg’s budget speech on Tuesday evening when the project was the first he named while spruiking the Federal Government’s infrastructure spend.

“(We’re) building the infrastructure our economy needs for the future with our 10-year, $110 billion investment pipeline,” he said.

“Tonight we make $15 billion in additional infrastructure commitments including for the North-South Corridor in South Australia.”

The next stage of the North-South Corridor project, which is expected to create about 4000 jobs, has been allocated $2.6bn in the budget – a re-announcement of funding from 2019.

It will pay for planning, design and construction work on a 6km motorway from Darlington to Anzac Highway.

This work will also include about 4km of tunnels.

However, construction work will not begin until late 2023.

As The Advertiser reported on Monday, the Civil Contractors Federation SA raised concerns about the time lag between government budget announcements and construction start dates.

“Far too much time passes between these events,” Federation chief executive Rebecca Pickering said.

“There needs to be greater accountability of state government and agencies to minimise this time and get on with construction.”

The Opposition said “we need construction work underway” given SA has the worst unemployment rate in the nation.

The Advertiser reported on Sunday that as part of the $3.2bn promised for major SA infrastructure projects, $161.6m will go towards a Truro bypass; $148m will be directed into stage two of the Augusta Highway duplication; and an extra $64m will be injected into the Strzelecki Track upgrade, bringing the Federal Government’s total funding for the outback project to $164m.

Other transport infrastructure funding for SA includes $3.6bn for nationally significant road projects; $374.2m to tackle urban congestion; $155.8 for the Adelaide City Deal; $210.8m for local roads and community infrastructure; and $222m to improve access routes to essential services, markets and employment opportunities.

SA will also receive $19.5m for bridge upgrades and $21.6m to improve safety and productivity of heavy vehicles.

so is there actually anything new in this budget or are they just rehashing an earlier budget?

The Penola Bypass is only one lane in each direction, so it could well be that here as well. However, the road through Truro does carry 7,200 vehicles per day, which is getting close to the threshold of needing 2 lanes in each direction.

The Truro bypass means that once you leave Adelaide, you don't go through another town until Renmark.

Stage 2 of the Augusta Highway redevelopment means that between Adelaide and Port Augusta, the only town you will travel through will be Port Wakefield.

But on the Dukes Highway to Melbourne, you will still have to slow down (considerably) for Tailem Bend, Coomandook, Coonalpyn, Tintinara, and Keith. And from Tailem Bend on it's single lane, with occasional passing lanes. Surely there are morer than 7200 vehicles a day on this route?

Not really. Tailem Bend to Keith is about 4000 vehicles per day, and Keith to Bordertown about 3000.

Dublin to Port Wakefield is about 8000 vehicles per day, with 4800 branching off to the Copper Coast and Yorke Peninsula, and 3700 north along the Augusta Highway (obviously this increases exponentially during long weekends and in the holidays).

I'm pleased to see a Truro bypass also planned. The planning stages for that could also include the early design of a modern railway over the ranges in that area. The design that might have been done to extend the Truro Railway Line to Sedan in the 1910s is probably no longer suitable, particularly since it passes through the town.

How would proposals from the early 1900s or the quashed GlobeLink be relevant to the road bypass?

In any case I wouldn't be surprised if the Sturt Highway diverges onto part of the old rail corridor (widened, obviously) near Kapunda-Truro Road which would point it in the right direction to continue around the town to the north of Truro Oval where it would then continue east and meet back up with the Sturt Highway.

so all this truro bypass thing has nothing to do with sending trucks north from murray bridge to truro, and as a result keeping trucks off the SE freeway and keeping them out of the city (toll gate/crafers etc)??

It will improve speed and safety for both residents and trucks through that area, and I'd expect remove the winding bit at the top of the hill. Since rural railways were closed, there are road trains from Loxton grain terminal to Outer Harbor.

A consequence will be that it makes the trip from Halfway House Road to Adelaide and north slightly quicker and easier. That is the northern part of the current heavy vehicle route north from Murray Bridge to the Sturt Highway. It's possible that some operators will consider it the tipping point to change their route.

So reducing the road trains past Truro primary school might increase the road trains past Cambrai primary school which would increase the pressure to continue to upgrade that route.

Next year's or 2026 election might contain alternatives of further upgrading the east-of-the=hills (previously GlobeLink) from one side, and Short South (Mount Barker Springs to N-S Motorway near St Mary's) from the other side.

Well that surprises me, but thank you for the info.

According to the Department for Infrastructure and Transport (DIT) service relocations for the remaining T2D section will start by the end of the year. The contract for those works will be of a similar cost to the whole of the recently opened R2P project.

That's an impressive cost when you consider that services should only need relocation near the tunnel portals, as the rest of the tunnels can be below the existing services.

Presumably property acquisition has to precede service relocation, as the services would often be getting moved aside further than the width of the current corridor.

Has it been announced whether the tunnels will go below the River Torrens, Keswick Creek and Brownhill Creek? They are all in the second stage north of Anzac Highway.

From InDaily's Budget 2020 summary:
https://indaily.com.au/news/2020/11/10/ ... -measures/

• A 4.3km southern tunnel from Darlington to just south of the Glenelg Tram bridge

• 1km of lowered motorway under the Glenelg Tram line and Anzac Highway

• 2km surface motorway from Anzac Highway to just south of Richmond Road then a lowered motorway under Richmond Road

• A 2km northern tunnel under Sir Donald Bradman Drive ending just south of West Thebarton Road

• 1.1km of lowered motorway under West Thebarton Road until south of the River Torrens and then a surface motorway until the tie-in with the Torrens to Torrens section

I would think there would be some services that could be relocated without property acquisitions having been started. The rest as they become available.

A reference design is due out by the end of the year which will give more certainty.

That sounds like surface level bridges over Brown Hill Creek (just north of Anzac Highway) and the Torrens, but could tunnel under Keswick Creek (between James Condon Drive and Sir Donald Bradman Drive).

Agree with the Torrens and Brown Hill Creek, but my guess for Keswick would be that the lowered motorway under Richmond Road would continue past James Congdon (and Keswick Creek) which would make building access ramps easier, then it would transition into the northern tunnel between James Congdon and Sir Donald Bradman.

I had not thought about the two creeks until recently. I wonder what the 2015 plan did about Keswick Creek, since that had an interchange in that area too.

I think there are culverts under Anzac Highway that can divert some of the flow to Brown Hill Creek, but I doubt they are big enough to divert the entire flow.

Have to admit I've kind of lost track of whats happening with this from over here, but if this is the current proposal it makes not sense to me. From what I understand of the above, they are planning a hugely expensive tunnel ,underneath what is largely heavily commercial/industrial South Road, but then a surface motorway through very residential, more tree lined stretch of the same corridor? I would have thought as per the previous governments proposal, the only stretch that really required a tunnel would be the Mile End/Thebarton precinct, with mainly lowered motorway for the rest. There is no way a surface motorway should be considered for the Richmond/ Glandore area. It should be trenched for noise abatement. Adelaide is flat-noise will be a big issue, and ugly noise walls are not a solution for these suburbs.
