Core Event: Bulldozers Begin Work on Border Infrastructure in Santa Elena Canyon
In early August 2026, federal contractors moved heavy machinery into the Santa Elena Canyon area of Big Bend National Park, clearing desert shrubs and marking a construction path with pink ribbons. Video captured by activists shows bulldozers preparing the ground for patrol roads, vehicle barriers and surveillance equipment along the park’s 118-mile stretch of the Rio Grande border.
Background & Context
The project is part of the Trump administration’s “smart wall” expansion. Congress allocated $46.5 billion for border-wall projects on July 4, 2026, and the administration shifted from a 30-foot steel wall in the park to a plan that includes roughly 200 miles of patrol roads, four non-contiguous vehicle barriers totaling 17 miles (about 6 ft tall), and electronic monitoring systems. Southwest Valley Contractors of New Mexico secured a $1.7 billion contract in May 2026 to carry out the work.
Data & Statistics
- Funding: $1.7 billion contract for park work; $46.5 billion overall border-wall appropriation.
- Infrastructure: ~200 miles of new patrol roads; 4 barrier sections (?17 miles total, 6 ft high).
- Park size: 800,000 acres; 118 miles of U.S.–Mexico border within the park.
- Crossings: CBP reports illegal crossings in the Big Bend sector dropped to the fewest encounters along the Texas border in fiscal year 2025.
Official Statements & Responses
CBP spokesperson John Mennell initially denied that the bulldozers were linked to construction, later describing the work as soil-assessment for future projects. The Department of Homeland Security invoked a June 9 waiver to suspend dozens of environmental and cultural statutes—including the Endangered Species Act and NEPA—to accelerate the project.
Criticism & Opposition
The Center for Biological Diversity, represented by public-lands advocate Laiken Jordahl, has filed a lawsuit alleging that DHS’s environmental waivers violate due-process rights and constitutional protections. The People of La Junta for Preservation—a group representing Lipan Apache members—joined the suit, claiming the waivers exceed DHS authority and infringe on religious freedom.
Local river guide Billy Miller decried the work, saying the river is “being threatened as we speak.”
Conflicting Reports & Gaps
Sources differ on whether the bulldozer activity constitutes construction or preliminary surveying.
Verbatim Quotes
- “If we lose places like Big Bend, we never get them back,” — Laiken Jordahl
- “The river's being threatened as we speak,” — Billy Miller
- “What people are seeing right now is survey and design work – NOT construction of a wall through the park,” — Rodney Scott, CBP commissioner
What’s Next
The People of La Junta lawsuit seeks a temporary restraining order and a permanent injunction against any ground-disturbing activities in Big Bend. DHS has agreed to provide at least 30 days’ notice before commencing such activities, but plaintiffs argue the waiver already permits immediate work. The case, *People of La Junta for Preservation v. Dept. of Homeland Security* (W.D. Tex., No. 5:26-cv-05245), was filed this month and will proceed through the federal courts while construction continues under the current contract.
