Wollondilly and Camden residents are demanding more detailed alternative routes for the Outer Sydney Orbital Corridor be made available.
Outer Sydney Orbital Macarthur Action Group founder Andrew Simpson said the Transport for NSW information about the alternative routes was not good enough and residents deserved to be better informed.
The proposed M9 orbital route connects Box Hill in the north and the Hume Motorway, near Menangle, in the south. A Transport for NSW spokesman said corridor options were presented in the draft Strategic Environmental Assessment.
However, Mr Simpson said the long list of alternative routes provided in the assessment were just “coloured lines on a map”.
Mr Simpson said Transport for NSW started the community consultation process for the orbital in 2015 but it was inadequate because the orbital was overshadow by discussions on the south-west passenger rail link from Oran Park to Narellan.
“In 2015, Transport for NSW said that when it came time to preserve the corridor for the orbital that the community would be consulted on the shortlist of options for the route,” he said. “It is only reasonable and fair that we get that information.
“We need more detail. We can’t tell where the routes are going from the map of the long list of options.”
Mr Simpson said it was not the job of residents to tell the government where the corridor route should go because they were not privy to all the technical information.
“Our submissions are monitored live so the department knows that we want to know the alternative routes,” he said. “So why can’t we get an answer?”
The department spokesman said engagement with the community and local councils identified a preference to consider other corridor alignments, particularly further west of established communities in Cobbitty and Ellis Lane.
