The Ghiglione Creek Bridge (Structure No. 9830-011P) in Denali National Park & Preserve underwent a routine inspection on August 21, 2023. The Federal Highway Administration identified several deficiencies, classifying the structure with a "B" (Major) priority for improvement, indicating it is seriously deficient or presents a safety hazard but can remain open with reduced loads or frequent inspections. Key issues include significant erosion of the approach embankment at the southeast and southwest corners, with rills almost cutting back to the roadway. The report also notes spalling of the curb and concrete endwall/wingwall at the east abutment, missing anchor bolts at the west abutment, and a typical broken weld with girder shift. The structure, built in 1960, is scheduled for replacement in the near future. It also requires inspection immediately following any significant seismic event. The bridge has a scour critical rating of 5, indicating scour within the limits of the footing or piles. Load ratings are provided for various truck types, with the capacity meeting or exceeding the design load (HS 15).
