Miss. Code § 19-13-51
The board of supervisors of any county shall have the power, in its discretion, to allow damages sustained to stock and other property injured or destroyed while traveling along the public highways maintained by the county where such loss is caused by defects in a bridge, causeway or culvert in such highway. No such payment shall be allowed unless such defect in such bridge, causeway or culvert was the proximate cause of the injury and was not apparent or discoverable by the exercise of reasonable diligence, and no such payment shall be made unless such defect had existed for such a time that the failure to remedy or repair the same amounts to gross carelessness on the part of the county. Such payments shall be made from the county road and bridge funds.
