Fair Condition = If any of the condition ratings (deck, superstructure, substructure, or culvert) are 5, or either of the appraisal ratings (structural evaluation or waterway adequacy) are 3 or 4. 4 Poor Condition = If any of the condition ratings (deck, superstructure, substructure, or culvert) are 4 or less, or either of the appraisal ratings (structural evaluation or waterway adequacy) are 2 or less. (This is defined as Structurally Deficient). Structural Evaluation is an appraisal rating that in plain English describes an overall rating of the condition of the bridge structure. This is the summary of the separately rated conditions of the structural components of the bridge. This is the truest measure in the National Bridge Inventory of the structural fitness of a bridge. e The Waterway Adequacy Appraisal Rating is a general assessment of the waterway opening with respect to the passage of flow through the bridge. This rating is based upon the frequency of "overtopping" of the bridge and approach (and the resultant traffic delays). The functional class of the roadway is also taken into consideration.
