Mayor Roxann Wedegartner said the testing initiative is a collaboration between the city, the state, the college and CIC Health of Cambridge, which is doing the tests and providing the results to individuals. GCC at One College Drive is hosting the site in Sloan Theater. GCC has been closed to in-person learning since last spring.
