The U.S. Supreme Court on Monday cleared the Trump administration to resume construction of border barriers and related infrastructure in the Big Bend region of West Texas, including portions of Big Bend National Park. The justices granted the administration's emergency request to lift an injunction issued by a federal judge while a lawsuit challenging the project proceeds.

The dispute centers on the administration's plans to expand border security infrastructure across the remote Big Bend sector, which stretches more than 300 miles along the U.S.-Mexico border. The project includes a combination of border walls, vehicle barriers, patrol roads and surveillance equipment.

The Trump administration has argued that additional infrastructure is necessary because of illegal border crossings, drug trafficking and cartel activity in the region. Federal officials have described Big Bend as an area of high illegal entry, citing more than 89,000 apprehensions between 2021 and 2025.

The plans call for most construction to take place on privately owned land. Within Big Bend National Park, the government intends to install approximately 17 miles of noncontiguous vehicle barriers rather than the 30-foot pedestrian wall planned for other sections of the southern border.

The legal challenge was brought by environmental advocates, a local river guide and a group seeking to preserve a historic church. They argue that the administration improperly used federal authority to bypass environmental and historic-preservation requirements, warning that construction could damage wildlife habitats, public lands and the Rio Grande corridor.

In October, U.S. District Judge Kathleen Cardone halted construction, finding that the challengers were likely to succeed in arguing that the administration exceeded its legal authority. The Supreme Court's decision allows the project to proceed while the broader lawsuit remains unresolved.

Justice Ketanji Brown Jackson indicated that she would have denied the administration's request for emergency relief.
