I am advised:
Transport for NSW committed to completing a Speed Zone Review for this section of the Bruxner Highway.
On 25 August 2022, the Speed Zone review commenced and is expected to take eight weeks to complete. The review will include engagement with local council, NSW Police, and members of the Local Traffic Committee. The review will be completed in line with the NSW Speed Zoning Guidelines which will include those safety concerns raised at the Alphadale intersection.
The outcome of the review will determine if any changes to the speed limit are appropriate.
