(CNN) Border Patrol agents are working with other law enforcement agencies and the military to put additional security barriers in place at the two ports of entry in the Texas border town of Eagle Pass, according to a release from CBP.

The additional material -- storage containers, traffic barriers and razor wire -- will "act as impediments to illegal crossers," Customs and Border Protection said.

"This is an unprecedented effort to try to keep these borders safe, to keep our communities safe, to keep the United States safe," Del Rio Sector Division Chief Louie Collins told reporters Friday.

About 1,800 migrants from Central America are being housed by the Mexican government across the Rio Grande in Piedras Negras. Some could be there for months as they wait to apply in the United States for asylum. Up to 20 cases can be processed each day, said Paul Del Rincon, port director for the Eagle Pass Port of Entry. So far, the people who have been interviewed were migrants who came before the caravan.

Border Patrol agents picked up a family of five Honduran nationals in the river near Eagle Pass on Friday morning. The two adults with three children were wading through tough currents as they attempted to cross near the Camino Real International Bridge, the agency said.

Members of the US Border Police guard the Rio Bravo, natural border between Eagle Pass, Texas and Piedras Negras, Mexico, on Thursday.
