Trump didn’t fulfill the signature promise of his 2016 campaign — to build a 1,000-mile-long wall along the Southwest border. Nonetheless, a substantial amount of fencing was constructed.
In total, 458 miles of “border wall system” was built during the Trump administration, according to a CBP status report on Jan. 22, 2021. Most of that, 373 miles of it, is replacement for primary or secondary fencing that was dilapidated or outdated. In addition, 52 miles of new primary wall and 33 miles of secondary wall were built in locations where there were no barriers before.
