Mexico–United States border wall
Definition
A series of physical barriers, including fences and walls, erected along portions of the 1,954-mile (3,145 km) international border between Mexico and the United States to deter illegal immigration, smuggling, and unauthorized crossings.
Not a continuous structure, it is supplemented by a 'virtual fence' system of sensors, cameras, and surveillance technology in areas unsuitable for physical barriers.
Prominently associated with U.S. border security policies, with major expansions under Presidents George W. Bush, Barack Obama, and especially Donald Trump, whose administrations oversaw significant new construction.
