Construction crews are erecting eight looming prototypes of President Trump's border wall in a remote section of the San Diego borderlands. Four are solid concrete; four are made of steel and concrete; one is topped with spikes. They all approach 30 feet in height. Customs and Border Protection is paying $20 million to six construction companies from Mississippi, Maryland, Alabama, Texas and Arizona. Crews in white hardhats operating cranes and forklifts are expected to complete the models by the end of the month.
