It is like a little city smack in the middle of Harriman State Park and it only took a couple of days to build: New York state's largest drive-thru COVID-19 testing center opened on Wednesday at noon.

At least 500 people were swabbed by midday Thursday, according to a public information officer on site.

Officials told Spectrum News, hundreds of state workers and recently activated National Guard members are planning to be working there for the next several weeks. This is good news for people who have been wondering when testing for the general public would be available.

The owner of PS Food Mart in Orange County, Kanchan Preet Singh, said he and his staff have close contact with hundreds of people each day and the ability to finally get his employees tested gives him peace of mind.

"We've been meeting a lot of people in one place and it sometimes makes you feel nervous," Singh said. "I think it's good for the people, good for the country. People can really get the help they're looking for."

The Harriman State Park testing center will be open every day from 7 a.m. to 7 p.m. for as long as necessary, officials said. Tests are by appointment only. Results usually come in after two or three days, according to a spokesperson, who added the whole point of these centers is to keep the hospital system from "crashing."

People encouraged to set up a test time include anyone with flu-like symptoms, anyone who has had contact with someone who might have the virus, the elderly, and anyone who already has a respiratory condition. Appointments can be made by calling 888-364-3065.
