[talk-au] Route number for Cross City Tunnel, Sydney [SEC=UNCLASSIFIED]

[Simon.Costello at ga.gov.au]

Hi there,
NSW Roads & Maritime Services is the authority on route numbering for NSW.
The A4 is effectively the City Westlink and Western Distributor.  See http://www.rms.nsw.gov.au/documents/projects/key-build-programs/alpha-numeric/sydney-imap.pdf.
The signs may be referencing how to get to the A4?
Thanks,
Simon

I can't make sense of it either … https://maps.six.nsw.gov.au should be the authoritative source in this instance but it just doesn't describe underground ways very well or at all in many cases. If you do modify the way can you please reference the source URL so if others want to contest it, change it again then we can dispute the credibility of the source rather than overwriting back and forth.

Does anyone here know the official route of NSW route A4 in central Sydney?

When I recently used the Cross City Tunnel, there were signs marked ‘A4’ westbound (the first one I was was at the exit to Sir John Young Crescent). However, on my return trip eastbound I didn’t see any route numbers (apart from the M1 exit). Does A4 officially follow the tunnel? (If so, is it only to the Eastern Distributor?) (OSM currently has it ending on the western side of the CBD.)

Thanks.

Mark P.
