Construction of prototypes for a future border wall has concluded in San Diego, officials with U.S. Customs and Border Protection announced Thursday.

The agency will now test and evaluate the finished products to determine which design elements meet its needs. The evaluation process could take a month or two.

Among the factors that will be considered with be whether the walls can be breached, climbed over, or dug under; whether they impede or deny traffic; and if they’re safe for Border Patrol agents.

“Border security contributes to our overall national security and relies on a combination of border infrastructure, technology, personnel and partnerships,” said acting Deputy Commissioner Ron Vitiello.

“Border walls have proven to be an extremely effective part of our multi-pronged security strategy to prevent the illegal migration of people and drugs over the years,” Vitiello said. “Specifically, walls are part of a border enforcement zone, which includes patrol roads, lights and surveillance technology.”

Plans for the wall served as a bitterly divisive centerpiece in Donald Trump’s ascension to the White House, drawing intense opposition from numerous California officials at the state and local level. California Attorney General Xavier Becerra filed a lawsuit in federal court in San Diego against the Trump administration, alleging legal and constitutional violations.

The prototypes, which range from 18 to 30 feet in height, were created by Caddell Construction Co. of Montgomery, Alabama; Fisher Sand & Gravel Co., Tempe, Arizona; Texas Sterling Construction Co., Houston; W. G. Yates & Sons Construction Co., Philadelphia, Mississippi; KWR Construction Inc., Sierra Vista, Arizona; and ELTA North America Inc., Annapolis Junction, Maryland.
