San Diego • The Trump administration has proposed spending $18 billion over 10 years to significantly extend the border wall with Mexico, providing one of its most detailed blueprints of how the president hopes to carry out a signature campaign pledge.
The proposal by Customs and Border Protection calls for 316 miles (505 kilometers) of additional barrier by September 2027, bringing total coverage to 970 miles (1,552 kilometers), or nearly half the border, according to a U.S. official with direct knowledge of the matter.
It also calls for 407 miles (651 kilometers) of replacement or secondary fencing, said the official, who spoke to The Associated Press on the condition of anonymity because the plan has not been made public.
