Talk:Sydney Harbour Tunnel

Untitled
This article could list some more fact about the tunnel: How many lanes of traffic, the diameter of the tubes for example.

Also, is anyone from the area familiar with this Transfield Pty Ltd? I searched for Transfield on Wikipedia, and the only article I found was for Transfield Services Limited. Are these the same company? If so, lets fix the link.CharacterZero 19:55, 27 March 2006 (UTC)

Lanes
2 lanes southbound, 2 lanes northbound.

Transfield
Transfield Services used to be owned by Transfield Holdings, they (Transfield Holdings) recently (2001) listed Transfield Services Ltd and subsequently sold off their construction business in restructuring the company, but remain the major shareholder in Transfield Services Ltd. It states this on both Transfield Services ( - read at bottom under 'Corporate Affairs') and Transfield Holdings websites.

Transfield History of projects

Timeline, move across to the right until 1992 where there is plenty of information on the Sydney Harbour Tunnel.

Dry Dock
When I was down at the Port Kembla site where the precast tunnels were built it was always called a "Casting Basin". It was never referred to as a "Dry Dock". Dry docks are permanent structures used in shipbuilding and repair. A casting basin is basically a large hole dug into the ground, there is no caisson, a earth bund wall seperates the sea from the work site. There are plenty of online engineering references to casting basins, a Google Scholar search reveals at least 4 or 5 references to the "Port Kembla Casting Basin" while a online NSW Parliment Hansard Search reveals 5 offical refereneces. The Port Kembla Casting Basin has also been referred to in secondary sources such as published by the large EPC concern Fluor. Surfing bird (talk) 02:51, 2 July 2008 (UTC)


 * Perhaps it is worth starting a dedicated casting basin article? Wongm (talk) 04:05, 2 July 2008 (UTC)

Yes, but we should wait till we can dig up enough references to prevent it being merged :( into the dry dock article. Surfing bird (talk) 04:19, 2 July 2008 (UTC)

Already cashless
Users of the SHT or SHB must pay with electronic tolling systems. The tunnel has been cashless for longer than the bridge. The only toll roads in Sydney that still accept cash is the M2 (after the M4 toll booths were removed earlier this year) and the Eastern Distributor.203.56.127.1 (talk) 21:21, 2 August 2010 (UTC)

Length
What is the length of this tunnel? — Preceding unsigned comment added by 203.26.123.208 (talk) 09:22, 18 January 2017 (UTC)

The only ?
Maybe the only current ... But it's the third, at least. Balmain to Greenwich Balmain coal to Cremorne Dave Rave (talk) 10:58, 26 June 2017 (UTC)

Construction photos.
Hi all

I've come across a great construction photo. Useable on wikipedia under a creative commons license if anyone has time...I don't at the moment. https://archives.cityofsydney.nsw.gov.au/nodes/view/706590
