So the RTA's own modelling showed the Rozelle Interchange would be a traffic disaster—but generating more toll road trips for Transurban was more important.
"The [NSW Roads and Traffic Authority] finalised the first business case for the WestConnex tunnel project in June 2013, with the help of road designers from around the world.
"[Paul Forward, a former CEO of the RTA] said the initial concept did not include the Rozelle Interchange.
...
"In 2014, an expert review group was formed to assess these plans.
"Mr Forward said it was at this point that TfNSW bureaucrats began to question the connectivity provided by the design.
"The RTA's former director of traffic Chris Ford told the inquiry that 15 alternative designs were modelled.
"Mr Ford said the modelling found that another motorway leading to the Anzac Bridge would cause congestion.
"'The issues that we see today were very clearly established in the modelling in 2014,' he said.
"In November 2015, after Mr Forward and Mr Ford were dismissed, TfNSW updated the WestConnex business case to include the tunnel to the Anzac Bridge, despite the congestion concerns raised by the modelling.
"In 2016, Transport for NSW updated the business case a second time ... creating a tunnel linking the Iron Cove Bridge to the Anzac Bridge."
...
"In 2018, the NSW government sold its 51 per cent stake in the Sydney Motorway Corporation, the body responsible for operating WestConnex, to Transurban for $9 billion.
"Mr Forward said the final design would generate a larger number of toll trips than previous options."
