Re: [NSW] Parramatta Rail Link - Details from EIS

["Nobody" <dweebken@NOSPAM.yahoo.com>]

I have a copy of the summary EIS. One detail you omitted is the bridge over
Lane Cove. It will be a massive concrete arch/pier structure (sorry poor
terminology - im looking at the impression!!!).
There are also some concerns reported in the papers about the increase in
truck activity on the north shore during construction, with an estimated 250
more trucks in some areas.
