Supreme Court Greenlights Border Construction in Big Bend National Park

The U.S. Supreme Court on Tuesday, November 10, 2026, lifted a preliminary injunction, enabling the Trump administration to resume construction of new border barriers, patrol roads, and other infrastructure within Big Bend National Park and its surrounding region. The decision overturns a lower court's order that had previously halted the construction. Conservation groups, including the National Parks Conservation Association and Sierra Club, had filed an amicus brief opposing the construction, arguing that national parks should be protected from harmful development. They are urging the administration to consider alternatives to damaging infrastructure in the park.
