West Airline and Marathon Ave in Garyville was closed this morning due an explosion at Marathon. SJSO has advised that this intersection has now been reopened.

Just before 9:30 a.m., St. John Parish residents reported hearing a “loud boom” near the Marathon plant. On social media, some individuals reported hearing the boom as far away as Destrehan and Ponchatoula.

This story is still developing, and more information will be released as it becomes available.
