The U.S. government gave the media a first peek Wednesday at construction of prototypes for President Donald Trump's proposed border wall. Crews working on two of the eight prototypes moved dirt, with one of the crews also installing steel reinforcing bars before concrete is poured. Each crew gets only 18.2 square metres to work on their prototype, prompting some to do assembly work elsewhere before moving the structure to their designated position. The rectangular construction zone is fenced off from public viewing in a remote area of San Diego along the border with Mexico. The government will consider the models to guide the proposed construction on the nearly 3,200 kilometre border with Mexico.
