The pattern, before the cases
Read these four the same way. A private consortium promises huge traffic. It doesn't come. The equity and lenders take a bath. The road itself — a genuine monopoly — is perfectly fine, so it's bought for a fraction of its build cost and keeps charging you exactly the same toll.
The four busts
Sydney — Cross City Tunnel (2006)
Forecast at roughly 90,000 vehicles a day; the first months ran nearer 34,000. The operator fell into receivership in December 2006 owing more than half a billion dollars — barely a year after opening. The tunnel now belongs, 100%, to Transurban, and still charges a toll. verified
Sydney — Lane Cove Tunnel (2010)
Same script. The operator hit receivership in January 2010. Transurban picked up the tunnel a few months later for around $630 million — and, again, the toll never stopped. verified price ~approx
Brisbane — Clem7 / RiverCity Motorway (2011)
The traffic forecaster, AECOM, projected more than 100,000 vehicles a day. Actual traffic was under 24,000. RiverCity Motorway collapsed into administration in February 2011, owing about $1.3 billion. Lenders sued AECOM over the forecasts; AECOM settled for around $280 million in 2015. verified
Brisbane — AirportLink M7 / BrisConnections (2013)
The forecaster (Arup) predicted around 135,000 vehicles a day; reality was closer to 50,000. BrisConnections went into voluntary administration in February 2013. Transurban's Queensland arm later acquired it — reportedly for around half its build cost — completing its Brisbane monopoly. Arup settled a forecast lawsuit in 2018. verified "half build cost" approx

Who actually lost — and who didn't
"The taxpayer didn't pay" is technically true in these cases and completely misses the point. Look at who bore the loss, and who was untouched.
| Who | What happened to them |
|---|---|
| Early equity investors | Wiped out — often small "mum and dad" and institutional shareholders sold a growth story. |
| Lenders / banks | Took big losses; chased the traffic forecasters through the courts for years. |
| The road (the monopoly) | Perfectly fine. Kept operating and tolling throughout, under new ownership. |
| The next buyer (e.g. Transurban) | Acquired a working monopoly for cents on the dollar — a bargain created by someone else's loss. |
| You, the motorist | Paid the same toll before, during and after the collapse. Nothing changed at the boom gate. |
The risk that was "transferred" was the risk of a bad bet — not the risk to you Yes, private investors lost money on their gamble. But the thing that was meant to protect the public — a fair price, a road that pays for itself and then goes free — never materialised. The toll is permanent; only the owner's letterhead changes. "Risk transfer" protected the government's talking point, not your wallet.
When it's an essential service, even the pretence drops
Toll roads at least let the private loss fall on private investors. But when the asset is something society cannot let fail — a hospital, a power network — the "risk" was never really the private partner's at all, because the government can't allow the lights to go out or the emergency department to close. When a private hospital operator collapsed in 2025, the state had to step back in. See the PPP hospitals → The deeper the service, the faster the risk flows home.
