About this file
This bridge inspection report documents the condition of the Ghiglione Creek Bridge located in Denali National Park and Preserve in Alaska. The three-span steel bridge carries Denali Park Road over Ghiglione Creek and is scheduled for removal as part of an upcoming roadway realignment project. Inspection findings include slope erosion at bridge corners that has almost cut back to the roadway, spalling concrete, bearing and girder issues, and light cracking in piers. The bridge's structural evaluation rate is 5 and it is considered scour critical. Rehabilitation or reconstruction is the proposed improvement with a priority of B for major work.

STRUCTURE SUMMARY STRUCTURE NO. 9830-011P
GHIGLIONE CREEK BRIDGE INSPECTION DATE: 06/21/2021
It should be noted that this bridge is scheduled to be removed in the near future under an upcoming roadway realignment project. Installation of object markers at the bridge corners is recommended to help improve motorist safety until the bridge is removed. Slope erosion at the southeast and southwest corners of the bridge has almost cut back to the roadway and should be repaired. In addition, until removed this structure should be inspected for damage immediately following any significant seismic event.
222.5 APPROACH EMBANKMENT EROSION AT BOTH SOUTHEAST AND SOUTHWEST CORNERS OF BRIDGE. SIGNIFICANT RILLS IN
SOUTHEAST APPROACH EMBANKMENT HAVE ALMOST CUT SLOPE BACK TO ROAD.
