Reinforced walls and detection technology: The ‘smart wall’ the US is building on the border
The U.S. government is reinforcing the border wall with Mexico and now describes it as a “smart” one. Following the 2025 passage of Donald Trump’s “Big, Beautiful Bill,” which includes a $46.5 billion budget package for border infrastructure construction, the United States is expanding and erecting new 32-ft-high steel bollard walls (nearly 10 meters), transforming water barriers, building roads, improving lighting, and installing high-tech detection tools such as infrared cameras and motion sensors. In addition, the area will be constantly monitored by U.S. Customs and Border Protection (CBP).
