President Donald Trump has boasted in the past that '[w]e have already built large new sections' during his time in the White House.
Border barriers erected between the U.S. and Mexico since Inauguration Day 2017 have consisted of supplements to existing walls and replacements for outmoded or decreipt barriers.
But '[t]he first new wall project, where no barrier currently exists, is anticipated to start in April,' CBP spokesman Roger Maier said in an email. He identified Hidalgo County as the construction project's location, a border zone along a meandering 50-mile stretch of the Rio Grande.
CBP said last year that it was 'designing and constructing approximately 25 miles of levee wall system' in that county, whose anchor is the the border city of McAllen.
President Trump visited McAllen on January 11, boasting of wall renovations that he framed as 'new' construction. 'I will say, we've done a lot of renovation. And we have a lot of new wall going up where we took down wall because it was in such bad shape, and we put new wall up,' he said.
