Condition
Deck: Fair [5]
Superstructure: Satisfactory [6]
Substructure: Good [7]
Loading
Design: M 13.5 / H 15 [2]
Operating: 25.9 metric ton = 28.5 tons (Load and Resistance Factor Rating (LRFR) rating reported by rating factor (RF) method using HL-93 loadings [8])
Inventory: 20.1 metric ton = 22.1 tons (Load and Resistance Factor Rating (LRFR) rating reported by rating factor (RF) method using HL-93 loadings [8])
Appraisal
Structural: Somewhat better than minimum adequacy to tolerate being left in place as is [5]
Deck Geometry: Basically intolerable requiring high priority of corrrective action [3]
Road Alignment: Equal to present minimum criteria [6]
Waterway: Better than present minimum criteria [7] and Bridge foundations determined to be stable for the assessed or calculated scour condition. [8]
Inspections
Date: November 2020 [1120] and Frequency: 24
Future Work
Work Needed: Replacement of bridge or other structure because of substandard load carrying capacity or substantial bridge roadway geometry. [31]
