Main Spans: 1 at 39.6 m = 129.9 ft
Approach Spans: 3
Skew: 0
Width, Roadway: 3.4 m = 11.2 ft (1 Lanes) and Out-To-Out: 3.9 m = 12.8 ft for a 3.7 m = 12.1 ft approaching roadway.

Loading
Design:
Operating: 28.8 metric ton = 31.7 tons (Load Factor(LF) [1])
Inventory: 17.2 metric ton = 18.9 tons (Load Factor(LF) [1])
Appraisal
Structural: Meets minimum tolerable limits to be left in place as is [4]
Deck Geometry: Basically intolerable requiring high priority of corrrective action [3]
Road Alignment: Basically intolerable requiring high priority of corrrective action [3]
Waterway: Equal to present desirable criteria [8] and Bridge is scour critical; bridge foundations determined to be unstable. [3]
Inspections
Date: May 1999 [599] 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]
