Despite its practical importance, the Manchac Swamp Bridge is also associated with local legends and folklore. The bridge stretches over a swamp, rumored to be inhabited by a Rougarou (a Cajun werewolf, also called loup-garou) and a voodoo princess. While driving across the bridge is perfectly safe, those swimming in the swamp below should exercise caution due to the presence of actual alligators lurking in the serene waters beneath the pier.
