The new website can be found at
asdastokemandeville.co.uk and will contain regularly updated information on ASDA's plans for the site as it progresses through the planning process.
As well as being able to find information, visitors to the website will also be able to submit any further questions they have about the proposal to the ASDA team.
Chris Marlow, ASDA's Property Communications Manager, said: "I'm very pleased to be able to announce the launch of the ASDA Stoke Mandeville website.
"We hope that the local community will find that it is a very useful source of information as ASDA develops its plans for the site.
"We will keep the site regularly updated as we fine tune our plans based on feedback from the local community and the various technical studies, including an in depth traffic analysis, that we have recently undertaken."
ASDA has received a substantial number of completed feedback forms that attendees took from a public consultation held last month and the company said it is pleased with the response so far.
The initial results are still being compiled, but an update will be announced in the coming days.
The new neighbourhood store will be located on Lower Road, Aylesbury, on a site to be vacated by Stoke Mandeville Hospital.
Plans for the site have been developed by ASDA and its partner, Morbaine Ltd, in partnership with the Buckinghamshire Hospitals NHS Trust.
The proposed store will have a sales area of 20,000 sq ft (1858 sq m). ASDA is planning to invest £20m in the new store and expects to create up to 250 permanent retail jobs for local people.
