Edgbaston Cricket Club ground is to be used as a giant coronavirus drive-through testing site for NHS staff.
Workers began erecting tents, marquees and portacabins at the Birmingham, venue today.
NHS England told the Mirror it hopes the drive-through site will be open and testing NHS staff by early next week.
Smaller sites in Shrewsbury and Wolverhampton opened last week but closed after a few days following government advice.
The first drive-through test centre for NHS staff opened at Chessington World of Adventures last week.
But today, it was reported just 75 people were tested at the south west London site, with images showing empty testing bays and lanes in the car park of the adventure park.
Officials were seen standing in face masks and gloves, apparently waiting for NHS workers to arrive.
Similar sites are in operation at an Ikea store in Wembley and North Greenwich in south London.
Public Health England facilities are taking up to four days to test samples - while German labs flying in to process swabs are said to offer results in two days.
Northampton General Hospital sent samples from 400 staff to the German labs of Eurofins Biomnis on Monday, say the Sun.
On Wednesday, UK testing stood at 10,657 for the day - while Germany is averaging 70,000 tests a day, reports the Sun.
So far, just 5,000 NHS staff out of half a million frontline workers have been tested.
Some NHS staff who had presented at the Chessington centre and the Wembley IKEA reported they were being turned away.
