Panattoni has taken over a Meta Platforms-backed plan to build a 430-acre data center in southern Wisconsin, spanning the towns of Beloit and Turtle. The project was previously being developed under Cambrin LLC, which shares contact details with an entity linked to Meta’s confirmed Beaver Dam data center in Wisconsin.
Panattoni has reportedly informed officials in the Town of Beloit that it is taking over the Meta Platforms-backed data center project in southern Wisconsin. The developer has also set up two websites for the project, though both were inaccessible at the time of reporting. Known as “Project Cornmaze,” the proposal has faced significant opposition from residents in Beloit and Turtle.
A Facebook group called “No Beloit Data Center” has grown to about 2,700 members, while a circulated flyer urges residents to push for a state-level moratorium on data center construction and for local bans on NDAs between developers and authorities. The site is owned by Rock Road Companies Inc, based in Janesville, Wisconsin, with pre-development talks ongoing since June 2025. Panattoni, founded in 1986, has built roughly 625 million sq ft of industrial and logistics space across the U.S.
