The Trump administration is accelerating construction of its $46 billion “Smart Wall” along the U.S.-Mexico border, combining new sections of 30-foot steel fencing with advanced surveillance technologies including artificial intelligence, autonomous towers, underground sensors, cameras, and fiber-optic detection systems. Officials say the project will strengthen border security while allowing Border Patrol agents to respond more efficiently, though critics warn it raises privacy, civil liberties, and spending concerns.
According to a report by Boston Herald, based on reporting from the Associated Press, the administration is rapidly expanding both the physical border wall and a sophisticated surveillance network designed to monitor nearly every section of the southern border.
What Happened
Following a major funding package approved by Congress, the Trump administration has allocated approximately $46 billion to complete and modernize border infrastructure.
Rather than relying solely on physical barriers, the administration’s Smart Wall combines:
- 30-foot steel border fencing
- AI-powered autonomous surveillance towers
- Ground sensors
- Infrared and radar cameras
- Underground fiber-optic detection systems
- Mobile surveillance vehicles
- River barriers and floating buoys
- Expanded patrol roads and lighting
Customs and Border Protection (CBP) officials describe the project as a technology-driven approach that improves border security while allowing agents to focus on enforcement operations.
Hundreds of Miles Already Under Construction
The administration says construction is moving quickly.
As of mid-June 2026:
- 74 new miles of border wall have already been completed.
- CBP reports construction is progressing at approximately six miles per week.
- Hundreds of additional miles are under contract.
- Roughly 535 miles of the nearly 2,000-mile border will rely primarily on surveillance technology because rugged terrain already serves as a natural barrier.
Officials are also upgrading existing wall sections with improved roads, lighting, cameras, and detection equipment.
Along portions of the Rio Grande in Texas, floating barriers are being installed to discourage illegal crossings and smuggling operations.
AI and Advanced Surveillance Expand Border Monitoring
Technology represents one of the largest components of the Smart Wall initiative.
The administration is deploying autonomous surveillance towers capable of:
- Detecting movement using radar and infrared sensors.
- Analyzing activity through artificial intelligence.
- Automatically alerting Border Patrol agents to suspicious activity.
Additional underground fiber-optic cables detect movement across remote terrain, while mobile surveillance towers can be relocated to changing migration routes.
CBP officials argue these technologies maximize the effectiveness of border agents by reducing the need for constant manual monitoring.

Critics Raise Privacy and Civil Liberties Concerns
Civil liberties organizations argue the expanding surveillance network creates new challenges for border communities.
The Southern Border Communities Coalition says increasing surveillance may push migrants toward more dangerous crossing routes while affecting the privacy of residents living near the border.
Some property owners have reported discovering government cameras and sensors installed near or on private land.
The Electronic Frontier Foundation also expressed concern over the growing use of artificial intelligence in border enforcement, warning that AI-based decision-making may introduce errors or bias while expanding government surveillance capabilities.
Questions Over Cost and Oversight
The Smart Wall project has also drawn criticism over its price tag.
The nonpartisan organization Taxpayers for Common Sense has questioned whether sufficient oversight exists to ensure taxpayers receive value for the billions being invested.
Critics point to earlier federal efforts to create a “virtual wall” using surveillance technology that were eventually canceled after significant cost overruns and technical challenges.
CBP maintains that robust oversight mechanisms remain in place and says today’s technologies are significantly more advanced than previous systems.
Environmental Concerns Continue
Although CBP recently announced it would not construct new 30-foot steel barriers through some environmentally sensitive areas in Texas, environmental groups remain concerned about planned patrol roads, lighting systems, and surveillance equipment.
Residents and conservation advocates argue additional infrastructure could affect wildlife habitats, dark skies, and protected public lands near Big Bend National Park.
What Happens Next
The Trump administration plans to continue expanding both the physical wall and its surveillance network over the coming year, with Homeland Security officials aiming to complete the initial phase of the project by mid-2027.
As Congress continues funding border security initiatives, the Smart Wall is expected to become one of the administration’s largest homeland security projects, combining physical barriers with artificial intelligence and advanced monitoring technologies to reshape U.S. border enforcement.

The Smart Wall combines traditional border fencing with AI-powered surveillance towers, sensors, cameras, fiber-optic detection systems, and other advanced technologies to monitor the U.S.-Mexico border.
Congress approved approximately $46 billion for construction, surveillance technology, and related border infrastructure under the Trump administration’s border security initiative.
