A federal judge has issued a two-week restraining order that blocks further construction at the immigration detention center in the Florida Everglades known as “Alligator Alcatraz.” U.S. District Judge Kathleen Williams granted the pause on Thursday while she weighs a request for a longer-term preliminary injunction. Environmental groups Friends of the Everglades and the Center for Biological Diversity, joined by the Miccosukee Tribe, claim state and federal agencies failed to conduct the environmental reviews required under the National Environmental Policy Act. They argue that expanding the facility—built on a former Miami-Dade County airstrip surrounded by wetlands—threatens protected habitats and could undo billions of dollars of ecosystem restoration efforts. The order bars additional filling, paving or other infrastructure work but allows the center to keep holding detainees for U.S. Immigration and Customs Enforcement. The detention site, developed by the Florida Division of Emergency Management as part of the Trump administration’s immigration crackdown, already houses hundreds of migrants. Judge Williams said she will rule on the broader injunction after further hearings scheduled for next week.
