Health officials test patients through a car window at the drive-through site.
Results come back within three days, and are sent by SMS.
Health workers screen visitors with a questionnaire about their travel history and symptoms. Only those deemed to be at-risk will be tested.
Those who have visited Daegu, for example, are deemed more vulnerable, as 73% of all coronavirus cases in the country stem from this southern city, according to South Korea's Center for Disease Control and Prevention.
Similarly, those who have links to the Shincheonji religious group in Daegu, connected to more than 50% of cases in the country, are deemed to be at risk.
About 100 workers in a gymnasium across the street from the drive-through site have been tasked with tracking down the 3,600 Shincheonji members believed to be living in Goyang.
One down-side to the drive-through test site is the Korean winter weather.
"It's hard because we have to wear protective suits, we can't go to the bathroom or drink water, and it's cold," says nurse Park Seung-hee, who normally works at the city's health center.
As cars coasted past, she and other nurses huddled by gas heaters, cupping heated pads in their hands. They work here in five-hour shifts.
When their shifts ends, they step fully clothed into a small portable booth called the "Clean Zone," in which they are showered in hypochlorous acid disinfectant.
It is all in a day's work at the drive through.
