The National Transportation Safety Board is expected to reveal what caused a cargo ship to slam into the Eggner's Ferry Bridge near Aurora in January 2012. The incident is the subject of part of a board meeting this morning in Washington D.C. Late on the night of January 26th, the Delta Mariner ran into the bridge, causing a 322-foot section of the span to collapse. The Delta Mariner was carrying an Atlas rocket booster and other components for the U.S. Air Force from Decatur, Ala. to Cape Canaveral. The missing span halted traffic on U.S. 68 between the western shore of Kentucky Lake and the Land Between the Lakes National Recreation Area.
