"We are committed to securing our border and that includes constructing border walls," CBP's acting deputy commissioner, Ronald Vitiello, said in a statement Tuesday.
"Our multi-pronged strategy to ensure the safety and security of the American people includes barriers, infrastructure, technology and people. Moving forward with the prototype enables us to continue to incorporate all the tools necessary to secure our border."
Six contractors from across the country have been selected to build the eight prototypes, half of which will be constructed of concrete and the other half of "other materials." The walls are to range between 18 and 30 feet high and succeed in one prevailing goal: "deter illegal crossings in the area in which they are constructed."
Once built, they will undergo testing by the Department of Homeland Security.
