In the UK at least the cost is way more than that! For instance, this scheme is priced at £106m (A$184m), the main features being a simple two bridge GSJ and around 1.5km of widening. I agree the Bruce Highway scheme looks expensive for what it is, but not completely out of whack with at least some other developed countries.

That's expensive for a scheme with just a single property displacement according to Google Earth. Though the interchange is built below grade which drives up the cost.

^ Yes, that will be a factor, and there are a couple of retaining walls and bridge widenings.

I didn't know about the plans for Reid/Tonkin:


In the UK this design is known as a 'partially-unrolled cloverleaf' - it's kind of a cross between a cloverstack and a cloverturbine.

For what its worth, these new sections of the Bruce Highway just south of Gympie do have a superbly smooth surface. Of all the roads I've driven on in Australia, Europe and North America, I think it is the smoothest I've ever driven on. I know it doesn't justify the enormous cost, but anyway..

The section between Rocky and Mackay looks to have had serious flood damage. There are several waves in the road which was making me feel a little car sick

Roe 8, Perth, Western Australia

Work to start on Roe 8 following contract award

The Western Australian Liberal National Government has approved a contract to build Roe 8, a key transport initiative which will significantly improve traffic flow across Perth's southern suburbs.

Premier Colin Barnett said Roe 8 - the 5km, four-lane dual carriageway extension of Roe Highway from the Kwinana Freeway intersection through to Stock Road - would deliver significant benefits to the Western Australian economy.

"Roe 8 is part of the 85km freight route from Muchea to Fremantle and will redistribute more than 6,900 trucks and 74,000 light vehicles per day from existing routes in the area," the Premier said.

Transport Minister Bill Marmion said a contract for the construction of Roe 8 was being finalised. Contract award to a consortium comprising CPB Contractors, Georgiou, WA Limestone, GHD, AECOM and BG&E was expected in forthcoming days.

"Roe 8 is an important component of the overall $1.9 billion Perth Freight Link Project," Mr Fletcher said.

Those are some great photos, essendon bombers! (btw I go for Essendon as well :P )
I drive the Tullamarine Freeway/Citylink regularly and it does need the upgrade. However imo it seems like too much work for an extra lane so far (in the 8 lane section).

Melbourne

Major Works Set To Transform Outer-Western Roads

Local residents and commuters out west will benefit from a huge package of road upgrade and maintenance works that will cut travel times, improve road safety and better connect communities in key growth corridors.

The Andrews Labor Government has called for Expressions of Interest for the western package of the Outer Suburban Arterial Roads (OSARs) Program – an Australian first, $1.8 billion investment.

It combines eight high-priority road upgrades with maintenance on more than 700 kilometres of road stretching from Werribee to Footscray, ensuring motorists benefit from new high quality roads while the existing network is maintained to a high standard for years to come.

The upgrades will involve a combination of duplication and widening works to western arterial roads including:

* Dunnings Road and Palmers Road, from Point Cook Road to Princes Freeway, Point Cook
* Palmers Road, from Princes Freeway to Western Freeway, Truganina
* Derrimut Road, from Sayers Road to Dohertys Road, Tarneit
* Leakes Road, from Fitzgerald Road to Derrimut Road, Truganina
* Dohertys Road, from Fitzgerald Road to Grieve Parade, Laverton North
* Dohertys Road, from Foundation Road to Palmers Road, Truganina
* Princes Freeway/Forsyth Road interchange, Hoppers Crossing
* Duncans Road interchange, Werribee/Werribee South

The package will transform the outer-western road network by boosting capacity and improving road pavement conditions with intersection upgrades, almost 30 kilometres of lane duplication, and road maintenance.

The Request for Proposal is expected to go out in early 2017, with construction expected to begin 2018.
Full press release: http://www.premier.vic.gov.au/major-...western-roads/

This is an interesting development. Large scale 'package' PPPs for urban arterials are uncommon, I cannot think of any similar project. They say it's an Australian first, usually big PPP contracts are for freeways, large bridges, tunnels or major highways.

On the surface, $ 1.8 billion for improving road pavement conditions with intersection upgrades, almost 30 kilometres of lane duplication, and road maintenance seems expensive, but these PPP projects usually involve a 20 or 30 year maintenance contract, and I'm not familiar with the exact upgrades that are proposed. Maybe others can elaborate on this. A$ 1.8 billion / 1.4 billion USD usually buys a large urban freeway, or a 100 km rural freeway project in the U.S., Canada or Europe.

Westconnex: New M4-M5 Link design features released

New design features for the next stage of WestConnex have been released, with potential for the M4-M5 Link twin tunnels to be completed early, capacity increasing from three to four lanes in each direction and exit and entry ramps at Camperdown removed.

Minister for Roads Duncan Gay said engineering improvements meant the twin tunnels from Haberfield to St Peters could be built as a stand-alone project, and initially operate independently from the Rozelle Interchange and Iron Cove Link. This would allow the tunnels to potentially open to motorists in 2022.

Maybe others can elaborate on this. A$ 1.8 billion / 1.4 billion USD usually buys a large urban freeway, or a 100 km rural freeway project in the U.S., Canada or Europe.

The road maintenance contract is for 20 years. If I recall correctly the benefit cost ratio is 4.4 and the arterial roads will remain toll free. The winning consortium in return will get annual assistance from the state budget. The six road upgrades (highlight red) and two upgrade interchanges (yellow circle) run through both residential, semi-agricultural and industrial areas.

It’s a good package of road upgrades although I would’ve liked to have seen more. Point Cook Road misses out. So does Ballan Road through Wyndhamvale. There Is proposal for future ‘Education City’ at East Werribee in which Sneydes Road runs through the middle of the precinct. Derrimut Road becomes Hopkins Road as you go north and leads to the Western Freeway at Rockbank. In years to come Rockbank will be itself surrounded by new suburbs. Nothing wrong with upgrading roads ahead of time.

I would like to know when roads within the 700km network require upgrading / duplicating five or ten years in the future who pays for it? Will it be written into the contract that the consortium funds future upgrades or will it come from the state budget which would fund both the upgrade and the maintenance contract?

The outer suburban roads program sounds promising, perhaps there will be packages for northern suburbs, south eastern suburbs too?? Arterial road packages sit nicely with level crossing removal upgrades as medium to large scale projects. The State Government a few months ago announced two packages of crossing removals, the ‘western’ package and the ‘north-western’ package containing eight projects each.

Legislation to revive the corruption-fighting Australian Building and Construction Commission (ABCC) looks set to pass through parliament. Hopefully this will help bring road construction costs down. http://www.skynews.com.au/news/top-s...-for-abcc.html

NorthLink WA

Stage 2 Contract awarded for NorthLink WA

The second of three construction contracts for the $1.12 billion NorthLink WA has been awarded to the Great Northern Connect Team - a joint venture between BGC Contracting Pty Ltd and Laing O'Rourke Australia Construction Pty Ltd.

The $417 million construction contract is for Stage 2 of the project and covers construction of the Central Section of the Swan Valley Bypass between the Reid Highway and Ellenbrook.

Western Australian Minister for Transport Bill Marmion said work would start with the 17 kilometre link between Benara and Maralla roads, then Reid Highway between Malaga Drive to Altone Road.

"Construction is well underway on Stage 1 of the NorthLink WA project with Tonkin Highway Grade Separations scheduled for completion by early 2018 - Stage 2 of the NorthLink WA project will begin construction early this year and is scheduled for completion in 2019."

The Australian Government is contributing $894 million and the Western Australian Government $223 million towards the NorthLink WA project.
Full press release: https://www.mediastatements.wa.gov.a...thLink-WA.aspx

This is a large freeway project northeast of Perth. The Swan Valley Bypass is 38 kilometers long.

How to build 5km of road in 2 days:

As a road engineer I can tell you that this solution has no change in surviving with reasonable traffic on it. It is more or less a "painting" that looks like a road.

It will keep the road dust free. But it's not really that much of a road indeed. It features no culverts, drainage or bridges.

Many roads on the American High Plains and the Canadian Prairies were built like that in the 1930s. Some of these states and provinces have an incredibly large network of paved roads relative to population.

In the U.S., lack of funding has led some states to turn them into gravel roads. In Canada, there are many weight restrictions during the spring due to thawing soil.
