OTAY MESA, Calif. – Nine months into his first term, President Trump’s proposed wall along the U.S.-Mexico border is finally beginning to take shape.

Eight architectural models of what the wall may look like are one week from completion at a construction site just miles away from the southwesternmost point of the United States. Each unique structure has been designed with the challenges border patrol officials currently face in mind, giving way to prototypes with razor wire edges or bottom-heavy cement foundations.
