BIG BEND, TEXAS — Federal contractors have moved heavy machinery into Big Bend National Park and are clearing land. A federal judge declined to block the construction this month, allowing the work to proceed.

The Trump administration is bypassing environmental laws for the project, which includes the construction of vehicle barriers, patrol roads, and surveillance technology. Homeland Security Secretary Kristi Noem waived certain federal laws related to environmental safety, historic preservation, and wildlife protection in February.

U.S. Customs and Border Protection stated that the current activity in the park is survey and design work, not wall construction. The agency outlined plans that include the construction, improvement, and maintenance of approximately 205 miles of 24-foot-wide patrol roads. In the Brewster County region, planned actions include the construction of 17 miles of a vehicle barrier system.

Illegal border crossings in the Big Bend Sector dropped in fiscal year 2025. The Big Bend Sector accounted for about 1.3% of apprehensions in fiscal year 2025.

Terrell County Sheriff Thaddeus Cleveland opposed the physical barriers. "We didn’t have to worry about any type of barrier. We had a God-made barrier," Cleveland said. Santa Elena Canyon features limestone cliffs that are 1,500 feet tall.

CBP Commissioner Rodney Scott defended the initiative. "The work is intended to help border patrol detect illegal crossings, respond faster, and assist visitors in danger," Scott said.

Why It Matters

The project proceeds in a landscape defined by natural features and established legal protections. Big Bend National Park was established in 1942 and serves as a major protected area along the southern border. The scale of the proposed infrastructure, including hundreds of miles of roads and barriers, represents an alteration to this environment.

The debate shows differing views on how best to secure remote border regions. While federal authorities emphasize operational needs and visitor safety, local leaders point to low apprehension rates and natural geography as reasons to avoid construction. The waiver of environmental and historic preservation laws removes standard regulatory hurdles, accelerating the timeline for potential completion.

Border county leaders asked the Department of Homeland Security to consult with them before implementing border security plans in April. Representatives Henry Cuellar and Veronica Escobar proposed an amendment to the homeland security appropriations bill in June to prevent barrier construction in the national or state park.

What's New

James Talarico criticized the project as wasteful and said it would divert resources from other border security needs. James Talarico alleged that the project will be built via sweetheart, no-bid contracts. James Talarico issued a statement blasting the Big Bend wall as a monument to corruption that no Texan asked for. James Talarico said, "We don’t need to wreck one of our nation’s greatest treasures by building an expensive wall on an already existing natural barrier." James Talarico said, "Every single one of them told me the same thing: this is irresponsible spending that no Texan asked for, enriching wealthy contractors without making Texans one bit safer." Attorney General Ken Paxton's spokesperson said Paxton wants to balance competing priorities. Attorney General Ken Paxton's spokesperson said he is committed to strong border security that protects Texans while considering the unique characteristics of different stretches of the border, including areas like Big Bend. Representative Lizzie Fletcher said, "I hope our Republican colleagues will join us, because this is not a partisan issue."

How Sources Differ
