The Secure Fence Act of 2006 (H.R. 6061) authorized and partially funded the construction of 700 miles of “fencing” along the Mexican border. (which included bollard barrier, as well as Normandy style vehicle barriers).
Other barrier building programs date back further - even some from WWII and earlier.
