The prototypes for President Donald Trump's proposed border wall along the U.S.-Mexico border have made their official debut.
For the last month, construction crews have been working in a fenced-off area in Otay Mesa on eight prototypes. U.S.
Customs and Border Protection unveiled them in a walking tour for the media Thursday morning.
CBP's acting deputy commissioner, Ronald Vitiello said, "the biggest impression I have is how big they are."
The prototypes stand about 30 feet tall, which is three times taller than the existing U.S.-Mexico border fencing, located just a few footsteps south of them.
The prototypes are blue, silver, beige and other colors. Some are solid concrete, others have metal columns spaced together so that Border Patrol can see incoming threats.
Over the next two to three months, Vitiello said the prototypes will be tested for their anti-climbing and anti-digging capabilities. In a separate, private location nearby, mock-ups of the prototypes will be tested for how difficult they are to breach with cutting torches, saws and other equipment — away from the eyes of smuggling organizations.
Vitiello said he isn’t sure if President Trump will visit the prototypes. He also said there is no guarantee the border wall will ever be built because the administration has yet to secure funding beyond $20 million for the prototypes and their testing. The border wall could cost more than $20 billion.
