Bulldozers Roll Into Big Bend: Border Construction Stirs Outrage at Famous Texas Park

Bulldozers have started tearing up land at the edge of Santa Elena Canyon inside Big Bend National Park in southwest Texas. The heavy machines are part of the Trump administration's plan to build new border security structures along the U.S.-Mexico border. The work has upset many people — including park visitors, local business owners, scientists, and politicians from both major parties. Big Bend is one of the most popular national parks in Texas, and critics say the construction could permanently damage its wild landscape.

Big Bend National Park covers about 800,000 acres of Chihuahuan Desert. It includes the Chisos Mountains and the Rio Grande River, which forms the border between Texas and Mexico. Santa Elena Canyon, where the bulldozers are now working, is one of the park's most famous spots. Tall cliffs rise 1,500 feet on either side of the river, making it a breathtaking place that thousands of people visit every year.

Activists and photographers first spotted the heavy machinery last week. Photographer Natalie Newman captured video of bulldozers pushing dirt at the canyon's entrance. Laiken Jordahl, a public lands advocate with the Center for Biological Diversity, called the scene heartbreaking. 'It's just devastating,' he said. 'They're bulldozing a brand new road through the most beloved stretch of the park.'

The agency in charge of the construction is U.S. Customs and Border Protection, or CBP. At first, CBP denied that the bulldozers had anything to do with border construction. A spokesperson said the machines were just fixing roads damaged by heavy rain. But later, officials admitted the bulldozers were preparing the ground for new roads and vehicle barriers — low fences meant to stop cars and trucks from crossing illegally.

CBP Commissioner Rodney Scott said the work is needed to keep the park safe from criminal groups. He called what people were seeing 'survey and design work,' not actual wall construction. However, opponents say the bulldozers are clearly breaking new ground and that officials are not being honest about the full plan. Bob Krumenaker, the park's former superintendent, said officials 'refuse to tell people what the complete plan is.'

The push to build in Big Bend started after Congress passed a large spending bill that President Trump signed into law on July 4 of last year. It included $46.5 billion for border wall projects. A company called Southwest Valley Contractors of New Mexico was awarded a $1.7 billion contract to build border security structures in the Big Bend area. CBP's current plan calls for about 200 miles of new patrol roads and four sections of vehicle barriers totaling 17 miles.

Many people wonder why so much money and effort is being spent here. According to the park's former superintendent, only about 100 to 125 people were arrested for crossing the border illegally inside the park each year in 2023 and 2024. That number likely dropped even more after President Trump began stricter immigration enforcement in January 2025. Critics say the cost and damage to the park are not worth it for such a small number of crossings.

To speed up construction, the Department of Homeland Security waived dozens of federal laws that normally protect the environment and cultural sites. Environmental groups say this is illegal and have gone to court to try to stop it. The Center for Biological Diversity and other groups are suing DHS, arguing that skipping those laws violated people's rights. DHS had earlier promised to give at least 30 days' notice before starting any ground-disturbing work in the park — a promise activists say was broken.

Politicians have had mixed reactions to the construction at Big Bend. Many Democrats in Congress have spoken out strongly against it, pointing to the low number of border crossings and wide public opposition. Texas Republicans have mostly stayed quiet, though Senator John Cornyn did write a letter asking officials to pause construction and listen to local voices. Governor Greg Abbott's office said rugged areas like Big Bend are good places to use technology for border security, but avoided commenting directly on the bulldozers.

Activists are worried the project will not stop at vehicle barriers. They point out that the original plan called for a full 30-foot steel wall, which CBP scaled back after public backlash. Jordahl said he does not trust that the smaller plan is truly the final one. 'They have the money they need to build a whole border wall through the national park,' he warned. For now, the bulldozers keep working, and the fight over the future of Big Bend continues.
