Here Are the Official Specs for Trump's 'Big, Beautiful' Wall

We now have an idea of what President Trump's "big, beautiful wall" is going to look like after US Customs and Border Protection released two requests for prototypes Friday night, ABC News reports. According to NPR, Customs and Border Protection is asking contractors to mock-up one of two types of walls: a solid concrete wall or a wall with a "see-through component." The government wants the wall be "physically imposing in height," ideally 30-feet tall (thought it would settle for 18). It must be impossible to climb without a ladder or tunnel underneath up to 6 feet below ground. It also must stand up to attacks from sledgehammers, pick axes, torches, and other tools for at least 30 minutes (though four hours would be better), according to CNN. The requests for prototypes also stipulate the wall must be "aesthetically pleasing," at least on the side that faces the US.

More than 400 companies have expressed interest in building Trump's wall. They're being asked to build 30-foot-long prototypes in San Diego for Customs and Border Protection to analyze. The deadline for proposals is March 29. While Trump has put the cost of the wall at $12 billion, a recent MIT study says it'll be closer to $38 billion. Trump's proposed budget includes $3.1 billion in funding for the wall. Regardless of the final cost, the wall is on track to be one of the biggest construction projects ever undertaken by the US government. (More border wall stories.)
