U.S. Customs and Border Protection said Friday they would build 230 miles of new border barriers backed by sensors, lights, and cameras, spending about $4.5 billion allocated by Congress in September—including about 23 miles of new "secondary" wall and around 126 miles of "system attributes" in Arizona.
