During his presidential campaign, Donald Trump repeatedly stated he would build a wall and that Mexico would pay for it. A new wall is going up along the New Mexico's border with Mexico border.
For most of the New Mexico-Mexico border, road barriers are what separate the two countries, and it's easy to get through it on foot. Twenty miles of road barriers are being replaced with what is called a bollard wall.
Since Congress hasn't approved full funding for Trump's border wall, U.S. Customs and Border Protection plans on piecemealing sections together. This section of New Mexico's border was a high priority.
