U.S. Customs and Border Protection (CBP) has temporarily paused survey and design work for border infrastructure in Big Bend National Park following opposition from local residents, law enforcement, and elected officials. While the Trump administration initially planned more than 100 miles of border wall through the region, CBP recently stated it is not planning to construct a 30-foot-high barrier inside the park. Instead, the agency is evaluating alternative technology, such as autonomous surveillance towers, and improvements to existing roads.
The shift follows a 2025 determination by then-Homeland Security Secretary Kristi Noem, who waived environmental laws to expedite the construction of barriers and roads in the Big Bend sector. Local stakeholders, including bipartisan sheriffs from five counties and cattle ranchers, expressed concerns that physical barriers would restrict access to the Rio Grande, disrupt wildlife, and harm the local tourism economy. Outgoing Sen. John Cornyn (R-TX) also urged federal officials to consult with community members before proceeding.
CBP Commissioner Rodney Scott met with local judges and sheriffs to discuss the project's future. Terrell County Sheriff Thaddeus Cleveland, a Republican and former Border Patrol agent, stated that Scott agreed to consider local input for future construction at both the National Park and nearby Big Bend Ranch State Park. Additionally, Texas Gov. Greg Abbott (R) stated on August 17, 2026, that Homeland Security Secretary Markwayne Mullin assured him there would be no barrier construction of any type within the national park.
The pause in activity prevents immediate physical changes to the landscape, though environmental advocates like Laiken Jordahl of the Center for Biological Diversity report that heavy equipment used for initial surveying has already leveled terrain and removed native vegetation like cactuses. For residents in the five affected counties, the outcome will determine their legal right to access the river and whether federal environmental protections, currently waived, will be reinstated. If the government moves forward with vehicle barriers instead of walls, ranchers may retain access to water, but the exact design and location remain undecided.
The next steps involve a period of consultation between CBP and local law enforcement to determine a final plan for the region. Commissioner Scott indicated that a formal plan will not be announced immediately as the agency evaluates "technology options" to meet the administration's goal of zero illegal crossings. No specific deadline for a final decision or the resumption of construction has been reported. Provisions for the 100 miles of wall planned outside the park boundaries also remain under evaluation as the agency gathers stakeholder input.
