Wider roads: MPs Fiona Scott and Stuart Ayres announced plans to widen Castlereagh and Mulgoa roads and to add longer turning lanes at the Jane Street and High Street intersections.Upgrades to Castlereagh and Mulgoa roads are on the way, after an announcement that the previously planned Jane Street extension will become a broader fix for traffic travelling north and south.
Lindsay MP Fiona Scott and Penrith MP Stuart Ayres announced the $70 million preferred design — to be covered by $35 million each from state and federal governments — to reduce congestion through the intersections between Museum Drive on Castlereagh Road in the north and Union Road in the south.
The plans are now open to public input.
This funding was slated to extend Jane Street through Woodriff Gardens to help east-west traffic, but will now be used to widen Mulgoa and Castlereagh roads to three lanes and add more turning lane length along High Street (east and west) and Jane Street.
Ms Scott said the flooding under the railway bridge at Castlereagh Road also needed to be solved and widening the underpass would enable that as well as solving other congestion.
“Whilst we have this bucket of money there for this part of Penrith we have to fix this pinch-point and the best outcome is to fix the north-south flow,” she said.
Mr Ayres said the change in priorities was because Roads and Maritime modelling had indicated that the best way to alleviate congestion was to widen the north-south roads and create longer turning lanes on east-west roads to move more cars through the large intersections.
“We’ve done a lot of work and quite extensive traffic modelling for the main bottlenecks and the main thoroughfare of traffic and which direction people are travelling in,” he said.
“Sometimes up to 10 times more cars are moving in a north-south direction.”
He said they tested 14 designs in the modelling and this was the best outcome according to the RMS.
Mr Ayres said this would help alleviate traffic coming across Victoria Bridge by getting more cars across intersections and away from the pinch-points.
“We can absorb more traffic doing this than putting a road through here,” Mr Ayres said.
Ms Scott said the money had to be prioritised and this was the most effective way to spend it.
An extension of Jane Street across Woodriff Gardens in the future has not been ruled out.
