Trump's wall will cost billions

AZ Centeral -  resident Donald Trump's promised border wall could cost between $10 billion and $60 billion.

Or more.

It is clear Congress is girding for a fight over spending $1.6 billion on a project central to Trump's campaign promises.

“The idea of a wall of this magnitude has not been tried before.” Barzin Mobasher, Arizona State University professor of sustainable engineering

Honing in on the cost is difficult, primarily because Trump himself has offered shifting estimates and conflicting details.

This month, for the first time, he suggested that the nearly 2,000-mile border with Mexico could be secured with as little as 700 miles of wall. He has also variously suggested the wall could be 40 feet high or more. For now, the prototypes will be 18 to 30 feet high.
One thing is clear: Whatever its shape and length, a wall would be expensive. In September 2015, Trump told CNN it would cost $4 billion. By February 2016, he said it would cost $8 billion....
