The bungled opening of the final stage of WestConnex, the Rozelle interchange, is bad enough that veteran transport experts such as Michelle Zeibots at the University of Technology Sydney say only a royal commission can open the lid on how such debacles can happen.

“We need to know who thought it up, who pushed for it, who in the private sector and public service designed, sanctioned and signed-off on its various stages and what the nature of the interaction was between government and private sector business interests.”

WestConnex now looks likely to compel a second harbour tunnel, the proposed Beaches motorway and another segment of the M6 tollway.

“It’s a cycle. It goes on and on and on, where they just build a new motorway,” Zeibots said. “You get induced traffic growth, it creates a new bottleneck, a new set of traffic jams, they are bigger and they are more difficult to contend with than the previous one.”

“What a private toll-road company is motivated by is completely and utterly anathema to what a city needs in order to have a good and adequate transport network to support its economic and social exchange functions,” she said.
