Loading
Design: MS 13.5 / HS 15 [3]
Operating: 27.9 metric ton = 30.7 tons (Load and Resistance Factor Rating (LRFR) rating reported by rating factor (RF) method using HL-93 loadings [8])
Inventory: 21.4 metric ton = 23.5 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 desirable criteria [8]
Waterway: Equal to present desirable criteria [8] and Bridge foundations determined to be stable for the assessed or calculated scour condition. [8]
Inspections
Date: April 2020 [0420] 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]
