New surveillance 'smart wall' and physical barriers coming to Arizona-Sonora border

Border wall

Border wall construction has continued uninterrupted along Arizona's border with Mexico.

The Department of Homeland Security says new segments of its smart-wall system are being built along the U.S.-Mexico border in Arizona and Texas — marking the latest funding allocation for new border wall.

DHS says it's awarded five new contracts and a total of $3.3 billion to contractors building the so-called smart wall. It's a secondary barrier that the agency says will include roads, detection technology, cameras, lighting and a physical wall made out of steel bollards.

The federal government has spent $8 billion on the secondary wall project so far — part of larger immigration and border funding baked into the GOP-crafted tax and spending package.

In Arizona, Fisher Sand and Gravel is getting roughly $1.4 billion to build 19 miles of new wall and secondary wall and 136 miles of detection technology.
