M2 Widening

This post by Peter Hewitt:

I just discovered that submissions on the M2 Widening Project close in just over 2 weeks time (21 June)! Nobody seems to be publicising this, and it's quite hard to find out that date on the official websites.

I believe (but have been unable to confirm from any NSW government source) that the project includes filling in the gap between the two viaducts over Chilworth Reserve, which must surely be major construction work. Over what period of time (presumably including extended night work) and at what cost?

It seems to me that all this project does is to widen the funnel sucking traffic into the existing M2 "car park" nearing the Harbour Bridge, thereby further degrading access to the city from Beecroft!

I can find nothing on the Beecroft-Cheltenham Civic Trust website on this issue other than a submission made in February 2008. Then they said "The Trust would also oppose any widening of the existing carriageway because of the high impact on local amenity". The Trust should at least publicise the imminent closing of submissions. Or have we all given up?
