American was lead engineer for a 50-mile cable barrier installation to prevent errant vehicles from straying into the canals and to facilitate officer response to the crash locations along I-75 (Alligator Alley).  Alligator Alley is a 50-mile, four-lane divided interstate roadway with canals running parallel for most of the length along each side. The Florida Highway Patrol (FHP) brought attention to a disturbing trend of fatal crashes involving the canal. Errant vehicles crashed through the wildlife fence with the fence giving way and then collapsing back into place making it difficult for officers to locate the crash and avoid potential drownings. American designed an innovation cable system that integrated into the existing wildlife fencing. The system featured a solar powered strobe light that would be triggered upon impact allowing the FHP officers to quickly locate the crash site.
