OTAY MESA, Calif. (KGTV) - Eight border wall prototypes constructed in South San Diego County are in the process of being dismantled Wednesday, according to Customs and Border Protection officials.
"At this point, we have learned a lot from them, but we don't necessarily have a purpose or use for them anymore, and we will be bringing them down," a CBP official told CNN.

“Those are not things that the [congressional] language necessarily precludes and they're items that we have been able to add to our tool kit," added the official.
The prototypes, which stand 30 feet tall, are in the path of the secondary border fence project, a Border Patrol source told 10News.
The Department of Homeland Security hired companies to build the prototypes, which were finished in October 2017.
Over two months, Customs and Border Protection officials tested the walls using power tools, hand tools, and other methods. The CBP evaluated the prototypes to determine if anyone could get through by climbing or digging.

Some reports have suggested the prototypes didn't do well in tests conducted by breaching experts, though the results haven't been made public, CNN reported.
None of the companies that built the prototypes are currently building portions of the wall on the southern border, according to a CBP official.
