There are a number of different opinions on whether anchoring beneath a bridge is a homeland security violation. Some people believe that it is not a homeland security violation because the anchor does not pose a threat to the structure of the bridge. Others believe that it is a homeland security violation because the anchor could be used to climb the bridge or to attach explosives to the bridge. Ultimately, whether or not anchoring beneath a bridge is considered a homeland security violation depends on the interpretation of Homeland Security regulations.
