Donald Trump has famously promised to build a “big beautiful wall” at the U.S.-Mexico border. Its construction could take more than three years and cost $21.6 billion, according to a report by the Department of Homeland Security, which has requested proposals for design-build prototypes. In February, Trump claimed it “is getting designed right now.” During his campaign, the President seized on the wall as a simple solution to complex problems of security and immigration.
