The expansion will be in Barnstable, Berkshire, Franklin, and Hampshire counties. Three new free express testing locations will go up in Framingham, New Bedford, and Lynn.

The testing sites will be “winterized,” Baker said. “All of these sites will be able to deal with the fact that it is getting colder and winter is coming.”
