The DHS issued the following release on how the wall is working in places where it has been built.
WE ARE BUILDING THE FIRST NEW BORDER WALL IN A DECADE.
DHS is committed to building wall and building wall quickly. We are not replacing short, outdated and ineffective wall with similar wall. Instead, under this President we are building a wall that is 30-feet high.
FACT: Prior to President Trump taking office, we have never built wall that high.
Once funding was provided, DHS began construction of border wall exceptionally quickly, in some locations in as little as nine months from funding to building– a process that commonly takes two years or more in other parts of Government. By the end of FY 2019, DHS expects to have construction completed or underway for more than 120 miles in the areas it’s most needed by the U.S. Border Patrol. The pace of construction has picked up as initial limiting factors like land acquisition and funding have been addressed.
