At least one section of the border wall built by the Trump administration has at this point cost $29 million a mile. A six-mile section in the Rio Grande Valley along the Texas border was originally contracted at $145 million. But only five miles have been completed, and the Biden administration in its first day in office called a halt to further work.
More than 40% of all people apprehended for crossing the border illegally are stopped in the Rio Grande Valley. The wall “system” in the region was more expensive than other sections because of roads, lighting, cameras and other technology.
President Biden, in a Jan. 20, 2021, executive order, stated that ”no more American taxpayer dollars be diverted to construct a border wall” and directed “a careful review of all resources appropriated or redirected to construct a southern border wall.”
