The president of the United States, Donald Trump, has made it very clear on many occasions that he plans to build a wall between the USA from Mexico. His options have been narrowed down to 8 different 30×30-foot walls and one of these, or maybe all of these will serve as the wall differentiating the boundary between the US and Mexico.
These test walls alone cost $20 million dollars and building the wall across the complete border will take the cost more than $20 billion. The prototypes for the 2,000-mile long wall are done and are waiting for the cement to dry before they can be tested. These walls will be tested if they can be breached, scaled or dug under once they are ready. Check out the wall designs below.
