Bulldozers Begin Clearing Land for Border-Security Infrastructure in Big Bend National Park

The Trump administration’s “smart wall” initiative, funded by the $46.5 billion One Big Beautiful Bill Act, has shifted from a 30-foot steel wall to roughly 200 miles of patrol roads, four non-contiguous vehicle-barrier sections totaling about 17 miles, and extensive surveillance equipment. Big Bend National Park, an 800,000-acre Chihuahuan-desert preserve, accounts for roughly 1 percent of illegal border encounters.

• Arrests in park: Former superintendent Bob Krumenaker notes 100–125 CBP arrests annually in 2023-2024.

CBP spokesperson John Mennell first described the bulldozers as regrading rain-damaged roads, later saying crews were assessing soil for future work. DHS has waived dozens of environmental and cultural statutes, arguing the measures are essential for border security. Senator John Cornyn, in a letter to DHS Secretary Mark Wayne Mullin, requested a pause for additional local input.

Conservation advocates argue the work is unnecessary and destructive. Laiken Jordahl of the Center for Biological Diversity warned the project “will…inflict destruction…truly be irreparable.” Bob Krumenaker, now leading Keep Big Bend Wild, said the bulldozers are “obscuring what they are doing.” A federal lawsuit filed by the indigenous nonprofit People of La Junta for Preservation and the Far Flung Outdoor Center alleges the construction “substantially burdens” Native religious practices and harms tourism. Attorneys Roland Gutierrez and Dick DeGuerin represent the plaintiffs, asserting the waivers violate due-process rights.

Activist video shows bulldozers clearing mesquite and brush at the mouth of Santa Elena Canyon, preparing a new road and likely a barrier section. Bright pink ribbons now mark cleared paths where willow and mesquite once stood. Protestors near the Rio Grande chanted “No Big Bend Wall” and voiced concerns that “the river’s being threatened as we speak.”

CBP officials describe the activity as preparatory surveying, while activists and former park staff contend heavy machinery is already breaking ground for permanent infrastructure. CBP initially denied any connection to the border-security plan, later acknowledging soil-assessment work. No detailed timeline for completion has been released, and the review process for the waived statutes remains unclear.

• “What people are seeing right now is survey and design work – NOT construction of a wall through the park,” — Rodney Scott, CBP commissioner

• “They are obscuring what they are doing,” — Bob Krumenaker

• “They’ve shown time and time again that we have absolutely no reason to trust them,” — Laiken Jordahl

The lawsuit seeks an immediate injunction, arguing the DHS waiver violates constitutional protections. DHS has pledged at least 30 days’ notice before any “ground-disturbing activities” in the park, but no court ruling has been issued. CBP indicates additional road improvements and barrier installations will continue as part of the broader border-security effort, though specific milestones have not been disclosed.
