Anyhow, of particular interest to me is the area of "proposed" circuits ie. circuits which are in the pipeline, or where at some point.
So far, in the context of Australia, I have these (haven't fleshed out the descriptions yet):
Brisbane - Temporary street layout used for Indy 300 promotion a few years ago. During the mayor-ship of Sally-Anne Atkinson there were briefly plans for a ATCC race on a Brisbane street circuit.
Cronulla - In 1998 promoter Steve Sergeant drew up plans for a “Surfside 500″ V8 Supercar event on the streets of Cronulla.
Geelong - Geelong 500 was proposed in 1984 on the streets of Geelong.
Hobart - A street circuit ATCC race was proposed in Hobart in 1988.
Townsville - Street circuit to host round of the 2009 V8 Supercar championship.
Melbourne - Street circuit in Melbourne CBD put forward as possible location for a Touring Car round - the proposed layout is at the site of present day South Bank.
Sydney - Sydney’s Darling Harbour was to be the site of a sportscar race. The Rocks was also proposed as a possible site for an IndyCar race.
Hamilton Island - Hamilton Island in the Whitsunday was the proposed site of an ATCC round in the late 1980s, utilizing the islands airport.
Homebush - Street circuit to host round of the 2009 V8 Supercar championship. The circuit is located around the 2000 Sydney Olympic Games precinct.
Bunbury International Circuit [ Website ] - Venue was to be located in Bunbury, Perth, to host a round of the Japanese Formula Nippon series. Project on permanent hiatus since 2004.
Got me thinking about proposed circuits around the world. Now, there is a list of proposed circuits here - http://www.the-fastl.../_proposed.html - but I know there are plenty not listed.
What is missing? What is the most interesting proposed circuit? What about Australian proposals that I've missed?
