If there was ever a reality-show moment to tightening homeland security it would be right now, as President Donald Trump’s famous Big Beautiful Wall on the Mexican border is slowly becoming a reality.

U.S. Customs and Border Protection announced last week that the construction of eight prototypes for the much-discussed and much-needed border wall just wrapped up in San Diego.

U.S. Customs and Border Protection (CBP) announced today that construction for prototypes of the Border Wall has concluded in San Diego.

The prototype construction phase is complete. CBP will now test and evaluate the finished products, provided by industry, to determine which wall design elements meets our needs. This testing and evaluation period will last 30 to 60 days.

“Border security contributes to our overall national security and relies on a combination of border infrastructure, technology, personnel, and partnerships,” said acting Deputy Commissioner Ron Vitiello. “Border walls have proven to be an extremely effective part of our multi-pronged security strategy to prevent the illegal migration of people and drugs over the years. Specifically, walls are part of a border enforcement zone, which includes patrol roads, lights and surveillance technology. These border enforcement zones give our men and women of CBP the best possible conditions to maintain a safe and secure border.”

Some of the companies vying for the contract include Texas Sterling Construction Co. out of Houston, Caddell Construction Co. out of Alabama (who made two different prototypes) and W.G. Yates & Sons out of Philadelphia, Mississippi, who also made two. Some Arizona and Maryland companies are also in the race.

Border Patrol noted that there are several characteristics they are looking for in the designs of these walls. Anti-breaching capabilities, anti-climbing capabilities, anti-digging capabilities, impedance and denial of traffic and safety of Border Patrol agents all factor into the final choice.
