The structure is built primarily of steel and spans 2 sections, stretching 21.6 meters (71 feet) end to end. Daily traffic averages 50 vehicles, placing it in the lower-traffic tier of Oklahoma bridges. It is owned and maintained by County Highway Agency.
The latest FHWA inspection records show a deck rating of 0/9, superstructure at 0/9, substructure at 0/9. The weakest component sits in critical condition. Because at least one major component scores 4 or lower, this bridge falls in FHWA's Poor condition category. That category is not a closure order.
