Federal Judge Blocks Border Wall Construction in Big Bend National Park

In a significant legal victory for environmentalists, landowners, and local businesses, a federal judge in El Paso issued a preliminary injunction on Friday blocking the Trump administration from constructing heavy border infrastructure—including border barriers and patrol roads—within the Big Bend region, including Big Bend National Park. The ruling by Judge Kathleen Cardone halts further construction until a lawsuit filed by the Center for Biological Diversity and others is resolved. Cardone signaled that the plaintiffs’ constitutional claims against the border wall expansion are likely to succeed in court.

The order comes at a critical time: border wall construction is already underway in Hudspeth County, and an earlier court-ordered pause for much of the Big Bend region expired on September 30. In a document filed earlier this week, the agencies indicated they would soon move to file eminent domain cases against Big Bend area landowners who aren’t cooperating with the wall. The news marks a major win for those who have united to oppose the projects, part of a $46 billion effort by the Trump administration to line the southern border with a mix of 30-foot-tall steel walls, vehicle barriers, roads, and surveillance technology.

“It’s such an important day for this country, for Texas, for everyone who loves their public lands and the beautiful Rio Grande,” said Laiken Jordahl, national public lands advocate at the Center for Biological Diversity. A key issue in the lawsuit is whether the administration can waive environmental laws to expedite construction. Congress designated Big Bend National Park to protect our country’s natural wonders, and people come from all over the world to experience its star-filled skies and striking mountain ranges. Big Bend is no place for border barriers.

A spokesperson for the agencies defended their position, stating, “We stand by our assessment and remain confident in our legal authorities to secure the border while preserving the unique landscape of the Big Bend region.” Despite this, the injunction remains in place, offering a temporary reprieve for the region’s unique ecosystem and the communities that depend on it. The legal battle continues, but for now, the judge’s order ensures that Big Bend’s natural treasures remain protected from further construction.
