It's part of the Government's push to increase testing in the UK.
The COVID-19 testing facility is to open at Thornhill Park and Ride for the NHS and other key workers, the Department of Heath has confirmed.
The site will operate on an appointment-only basis and will be piloted for the first few days. We've asked the Government department when it is due to open.
Those tested will find out their results within a few days.
The Government is scaling up the national effort to boost testing for the virus after it set a target of testing 100-thousand people a day by the end of the month.
Capacity is still less than 40-thousand currently.
28 regional testing sites are open to date which will provide thousands more PCR swab tests.
Oxfordshire Cllr Liam Walker, Cabinet member for highway delivery and operations said: "We are working closely with the Department for Health and Social Care and other partners to enable the setting up of an isolated coronavirus testing area to test key frontline workers in one of the park and ride sites at Thornhill, in line with the governments national testing strategy.
"We are proud to be doing our part during this unprecedented time."
Health Minister Lord Bethell said: "This new service will help end the uncertainty of whether NHS and social care staff and other key workers need to stay at home, meaning those who test negative will be able to return to work.
"This is a national effort and we are proud to be working with a number of partners to turn this ambition into a reality and roll out additional capacity to where it is needed."
Professor John Newton, National Coordinator for the UK Coronavirus Testing Strategy, said: "New testing sites such as this one are a key pillar of our 5-pillar plan to scale up testing, and are critical in supporting NHS staff and other frontline workers who are isolating at home to return safely to work if the test is negative."
"This is a brilliant example of industries and businesses turning their resources to creating and rolling out mass testing at scale, which will help to deliver on our aim of carrying out 100,000 tests a day across the UK by the end of the month."
The testing centre is being operated in partnership with Serco and Boots.
