OTAY MESA, Calif. (KGTV) -- The piercing sound of a high-powered drill could be heard coming from the Otay Mesa border wall prototypes Tuesday morning.
Journalist Jorge Neito captured the images from a neighborhood in Tijuana. Construction workers could be seen drilling more than a dozen holes into the concrete barriers.
Customs and Border Protection officials confirmed to 10News last week that the prototypes were coming down to make space for a secondary border fence. That fence will strech 14 miles from the beach to Otay Mountain. Officials never specified when the prototype demolition would happen.
The prototypes are 30 feet high and were built in last September of 2017. President Trump toured the barriers in 2018.
Out of the eight designs there wasn't one specifically picked for the border wall.
"There was never an intent to pick one and copy that along the entire U.S. border. The entire concept literally was how can we do this better," San Diego Sector Border Patrol Chief Rodney Scott told 10News in 2018. "But we're not picking one of these walls over the other walls, and we never planned on doing that. So, depending on the terrain or the environment, it could be any one of these? Correct."
10News reached out to Border Patrol locally to find out if today's work is part of the prototypes' demolition and a spokesperson referred us to Washington D.C., so far we have not heard back.
