The new migrant detention center, nicknamed “Alligator Alcatraz,” is set to open in the Florida Everglades on July 1, 2025.
Construction of “Alligator Alcatraz,” Florida’s new migrant detention facility, began in early June 2025, with the project moving quickly to meet its planned opening in a couple days.
The facility nicknamed “Alligator Alcatraz” is officially called the Dade-Collier Training and Transition Airport (or TNT for short).

Contrary to claims, the facility is not on an island but is located on a 30-square-mile site at an abandoned airstrip in the Florida Everglades, about 45 miles west of downtown Miami.
Building the facility in the Everglades posed challenges, but the state repurposed the existing airstrip, adding structures and reinforced fencing to create a secure detention center for up to 5,000 criminal illegal aliens.
To minimize environmental impact, construction used prefabricated materials transported to the site, avoiding extensive land clearing in the swampy, alligator-filled region.
The facility’s remote location and natural barriers, like surrounding waters with alligators and pythons, enhance security without needing a traditional island setting.
The project has sparked debates across the nation due to its unique location, surrounded by swamps teeming with alligators and pythons, and its purpose as a staging ground for deporting criminal illegal aliens.

Florida Governor Ron DeSantis praised the project, stating, “This facility will be a game-changer, allowing us to efficiently process and deport illegal migrants while leveraging the existing infrastructure of the Dade-Collier Airport to support federal immigration efforts.”
What Is Alligator Alcatraz?
Alligator Alcatraz is a Immigration and Customs Enforcement (ICE) detention facility designed to hold criminal illegal aliens before their deportation.
Located in a remote, swampy area of the Florida Everglades near Miami, the facility is intended to act as a “force multiplier” for federal immigration enforcement, according to Florida Governor Ron DeSantis.

It will house up to 5,000 detainees at a time, making it one of the largest ICE facilities in the state.
The facility is a newly constructed site, not a repurposed existing building, specifically designed to stage illegal migrants for efficient deportation.
Its name, “Alligator Alcatraz,” stems from its location in an alligator- and python-infested swamp, which acts as a natural deterrent to escapes.
Florida Attorney General James Uthmeier described it, saying, “If somebody were to get out, there’s nowhere to run, nowhere to hide. Only the alligators and pythons are waiting.”
Who’s Behind Alligator Alcatraz?
The Idea
The concept for Alligator Alcatraz was proposed by Florida Attorney General James Uthmeier, who envisioned a secure facility in a remote location to deter escapes and streamline deportations.
The idea gained traction as part of Florida’s broader push to support federal immigration policies under the Trump administration.
Funding
The facility is primarily funded by the state of Florida, with support from federal resources under the Trump administration’s immigration enforcement initiatives.
The cost to build and operate the “Alligator Alcatraz” migrant detention facility in Florida’s Everglades is estimated at approximately $450 million annually.
This figure primarily covers operational costs, with some sources indicating that the construction itself is included in this annual estimate.
Funding is expected to be partially reimbursed by the Federal Emergency Management Agency (FEMA) or the Department of Homeland Security (DHS).
Florida Governor DeSantis has emphasized Florida’s commitment to investing in immigration enforcement to alleviate pressure on local jails.
Supporters
- Governor Ron DeSantis: A vocal advocate, DeSantis has highlighted the facility’s role in supporting President Trump’s mandate to enforce immigration laws. He stated on X, “Florida is stepping up to help increase deportations and fulfill President Trump’s mandate to enforce immigration law.”
- Florida Attorney General James Uthmeier: As the originator of the idea, Uthmeier has championed the facility’s strategic location and natural security features.
- President Trump: The Trump administration approved the facility, aligning it with broader federal immigration policies.
- Conservative Commentators: Figures like Laura Ingraham and Steve Gruber have expressed support, with posts on social media praising the facility’s innovative approach to immigration enforcement.
Opponents
Opposition to Alligator Alcatraz has come from various environmental and human rights groups.
Immigrant rights advocates and progressive groups have raised concerns about the facility’s conditions and its remote location, arguing it could endanger detainees’ safety and access to legal representation.
Critics also question the ethics of using natural predators as a security measure, citing potential human rights violations.
The facility is surrounded by alligators and pythons, as it is located in the Florida Everglades, a region known for its dense population of these animals.
The natural environment serves as a deterrent to escape attempts, as highlighted by Uthmeier’s quote about the lack of places to run or hide.
However, there is no specific count of how many alligators or pythons are in the surrounding waters, as their numbers fluctuate naturally in the Everglades ecosystem.
Who Will Be Detained There?
Alligator Alcatraz is designed to hold criminal illegal aliens—undocumented immigrants who have committed crimes in the United States—pending their deportation.
The facility is not intended for long-term incarceration but as a temporary staging area for processing and deporting detainees.
Once processed, detainees will be transferred to federal authorities for deportation.
Capacity and Operations
The facility can accommodate up to 5,000 detainees at a time, making it Florida’s largest ICE detention center.
It is designed for efficiency, with the goal of processing large numbers of detainees quickly to support mass deportation efforts.
Detainees will not stay long-term; their time at Alligator Alcatraz is temporary, lasting until deportation arrangements are finalized.
Illegal Border Crossings:
According to U.S. Customs and Border Protection (CBP) data, illegal border crossings have fluctuated significantly.
In 2024, CBP reported approximately 2.5 million encounters with migrants at the U.S.-Mexico border. As of mid-2025, preliminary data suggests a slight decrease, with an estimated 1.2 million encounters in the first half of the year, though exact numbers for June 2025 are not yet finalized.
This represents a roughly 20% decrease compared to the same period in 2024, attributed to stricter enforcement policies and international agreements. These numbers are subject to change as final reports are released.
Case Study: Illegal Crossings and Crime
The 2019 FAIR study on illegal immigration and crime found that undocumented immigrants have a higher crime rate than U.S. citizens, based on data from the federal SCAAP program, which tracks incarcerated illegal aliens.
It shows that in 2017, illegal aliens made up about 4.8% of the U.S. population but accounted for a larger share of certain crimes, like drug trafficking and violent offenses, with over 66,000 incarcerated for such crimes.
The study says this puts a strain on local jails and costs taxpayers billions. It suggests stronger immigration enforcement could reduce these crimes and costs. Reference: fairus.org
Alligator Alcatraz could help address this by prioritizing the detention and deportation of criminal offenders, reducing strain on local law enforcement.
