Route description
All of MS 531 is located in Smith and Jasper counties. The route is legally defined in Mississippi Code § 65-3-3, and is maintained by the Mississippi Department of Transportation as part of the state highway system. The section in Smith County was designated as Staff Sergeant Mark Haskin Eaton Memorial Highway in 2011, commemorating a member of the Army Special Forces killed in the Vietnam War.
