Trump Administration’s Big Bend Border Barrier Plans Face Legal Challenge and Construction Pause
By Drooid · · How we work
Core Event
The Department of Homeland Security (DHS) and U.S. Customs and Border Protection (CBP) are pursuing a $46 billion program to install 30-foot steel bollard walls, vehicle barriers, roads, lighting and surveillance across the remote Big Bend region of West Texas. On September 14, a coalition of six private landowners and the nonprofit Conserve Big Bend filed a federal lawsuit in Washington, D.C. seeking an injunction to halt all barrier construction, including work inside Big Bend National Park.
Background & Context
The Big Bend sector stretches roughly 517 miles—about one-quarter of the U.S.–Mexico border—and has historically recorded the lowest illegal-entry activity of any Southwest sector. The Trump administration classified the region as an “area of high illegal entry” to invoke expedited authority under Section 102 of the 1996 Illegal Immigration Reform and Immigrant Responsibility Act (IIRIRA), allowing the DHS secretary to waive environmental, historic-preservation and due-process statutes.
Data & Statistics
- The sector accounted for ? 1.3 % of total Southwest-border apprehensions in the most recent fiscal year, according to CBP data cited in the complaint.
- Over the past five years its share has hovered around 1.5 %, making it the least active sector.
- Contracts for three of the five planned “Big Bend Projects” were awarded on March 5 2026; a fourth on June 2 2026.
- CBP’s August 2026 field work in the park was halted on August 27, and the agency announced a pause on all ground-disturbing activity that will remain in effect through September 30.
Official Statements & Responses
DHS Secretary Markwayne Mullin defended the waivers as necessary to address “high illegal entry” and protect the nation. The agency said final construction plans are not yet finalized and any work inside the park will be limited to access roads and vehicle barriers rather than a full wall.
Criticism & Opposition
- Laura Allen, former Val Verde County judge, praised overall enforcement but urged the president to “let it go” in Big Bend, arguing the wall would divide families and ranches.
- Lico Miller, rancher with the People of La Junta for Preservation, warned that eminent-domain threats jeopardize Texas sovereignty and private property rights.
- Laiken Jordahl, environmental advocate with the Center for Biological Diversity, said trust in CBP has been “burned” by repeated reversals.
Conflicting Reports & Gaps
- Wall Height Inside the Park – Early CBP maps suggested a 30-foot barrier could be placed on private lands adjacent to the park, while later statements claim no 30-foot wall will be erected on the park’s cliffs.
- Scope of “High Illegal Entry” – The administration cites the designation to justify waivers, yet the lawsuit and agency reports highlight that the sector consistently records the fewest apprehensions of any Southwest sector. No independent audit of the designation has been released.
What’s Next
The court has 60 days to rule on the preliminary injunction request. CBP’s construction pause remains in effect until September 30, after which the agency may resume ground-disturbing activities unless a judicial order blocks them. The outcome will determine whether DHS can continue invoking IIRIRA-based waivers for the Big Bend sector and proceed with the $46 billion barrier program.
