Louisiana State Police are investigating a series of crashes on Interstate 55 that resulted in the deaths of eight people and injured 63. The crashes were caused by a combination of dense fog and smoke from marsh fires, which severely reduced visibility on the highway. The Louisiana Department of Transportation and Development (LaDOTD) does not typically close interstates due to fog, but some are questioning whether that policy should change in light of this tragedy. One victim of the crashes, Qutub Singh Negi, was described as a gentle and respected chef who was loved by his customers. As cleanup efforts continue and bridge repairs are identified, experts warn that similar conditions could occur if dry weather persists and marsh fires continue to burn. The Louisiana State Police and LaDOTD will need to evaluate their current policies in order to prevent future deadly crashes on Louisiana highways.
