SAN FRANCISCO (KPIX 5) — After KPIX 5 reported on Google’s mysterious project on a barge off Treasure Island, reports have surfaced of the tech giant building similar floating structures outside of the Bay Area.
A report appearing in the Portland (Maine) Press Herald showed shipping containers stacked on a barge in Maine – with the structure appearing virtually identical to the Bay Area barge. Also, an unconfirmed report suggested a Google barge is taking shape in New London, Connecticut.
