The security wall prototypes that will eventually lead to the final design for the border wall between Mexico and the U.S. began taking form Tuesday. The construction site is about two miles east of San Diego’s Otay Mesa border crossing at the end of steel-mesh fence that runs from the Pacific Ocean.
"Today marks a significant milestone in the implementation of the President's executive order on border security and immigration improvement," said acting chief border patrol agent Roy Villareal during a press event at the construction site.
Villareal said the prototype phase is expected to last 30 days and that he expects protests at the site during that time."We expect that there may be protesting and we are going to do everything to make sure that we provide that opportunity and we maintain civility and lawfulness along the border," he said.
San Diego police and the county sheriff’s department have helped set up a “free speech zone” nearby for people to demonstrate.
The companies chosen to build concrete prototypes are: Fisher Sand & Gravel Co. of Tempe, Ariz.; Caddell Construction Co. of Montgomery, Ala.; Texas Sterling Construction Co. of Houston; and W.G. Yates & Sons Construction Co. of Philadelphia, Miss.
The four companies that will build prototypes of alternate materials are: Caddell Construction and W.G. Yates & Sons, as well as KWR Construction of Sierra Vista, Ariz., and ELTA North America of Annapolis Junction, Md.
A green tarpaulin hangs on a chain-link fence to block views of the work. A Mexican man breached the fence and cut his hand before being arrested while preparations were made for a press conference about the wall.
