Attribute Definition:
This one digit field indicates the rating. It should be noted that the National Bridge Inspection Standards require the posting of load limits only if the maximum legal loads in the state produce stresses in excess of the operating rating stress level. However, a lesser stress level, as low as the inventory rating level, may be used to determine safe load capacity for any or all bridges. If the safe load capacity posting is required enter a "4" or less. If no posting is required enter a "5".
