From our sister site The B-Town (Burien) Blog:

Courtesy Sarah Toce comes word and photos that show that tents are being set up in the parking lot of the CVS Pharmacy located at 117 SW 160th Street in Burien (map below).

We called the pharmacy and a technician confirmed that the these tents will serve as drive-through coronavirus testing locations soon.

He did not know when the testing will begin though, and no public announcements or further details have yet been made.
