My electorate will welcome this because of the assistance it will provide in making it easier to get to and from the city. I think it will also help with the movement of freight between the airport and Western Sydney. I also place on record my view that more work needs to be done to expand the M5 Motorway. I am sure the member for Werriwa and the member for Macarthur would join me in that. My question to the minister is: can you give us some more detail on that feasibility study and how it will roll out. Can you tell us whether it would be a truck-only tunnel and, if that is the case, whether trucks would be banned from the existing tunnel, which would improve ventilation; and whether this project would be an opportunity to fix ventilation problems in the existing tunnel.'
