STRUCTURE EVALUATION SUMMARY

This concrete arch bridge is in fair condition overall. Problems at this time include flood damaged masonry on the upstream end of the north pier; loose stones at downstream end of south pier; deterioration of the curbs and sidewalks; open core holes in the asphalt pavement at three locations; deterioration of the southeast approach parapet masonry; vegetation growth along the wingwalls, overhanging the parapets, and growing from the abutment and pier joints; and deteriorated masonry mortar joints.

It should be noted that this bridge has had problems with settlement in the past due to possible loss of spandrel fill material. Ground Penetrating Radar was used in an effort to detect possible subsurface voids, and the findings were outlined in a letter to Mr. Kent Cochran of the Southeast Region dated September 28, 2014.

The FHWA Bridge Design office is currently evaluating rehabilitation alternatives for this bridge.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5140-106P

A (Critical) - Structure is closed, in imminent danger of collapse, or presents a critical safety hazard.

B (Major) - Structure exhibits severe deterioration, presents a safety hazard, or is designated a high priority due to age and/or condition.

C (Moderate) - Structure is deficient, functionally obsolete, or requires substantial repairs to prevent a serious deficiency or unsafe condition.

D (Minor) - Structure is generally in good condition. Preventative maintenance may be required.

E (Special) - Structure is under construction or reconstruction.

FIELD INSPECTION REPORT STRUCTURE NO. 5140-106P

G = GOOD (CODES 7 - 9) F = FAIR (CODES 5 - 6) P = POOR (CODES 0 - 4)

CONDITION RATING CODE EQUIVALENTS FOR SUB-ELEMENTS

SERIOUS CONDITION - loss of section, deterioration, spalling, or scour have seriously affected primary structural components. Local failures are possible.

Fatigue cracks in steel or shear cracks in concrete may be present.

CRITICAL CONDITION - advanced deterioration of primary structural elements. Fatigue cracks in steel or shear cracks in concrete may be present or scour may have removed substructure support. Unless closely monitored it may be necessary to close the structure until corrective action can be taken.

“IMMINENT” FAILURE CONDITION - major deterioration or sec ion loss present in critical structural components or obvious vertical or horizontal movement affecting structure stability. Structure is closed to traffic but corrective action may return structure to light service.

FAILED CONDITION - out of service; beyond corrective action.

CONDITION RATING CODES FOR ITEMS 58 - 62, 222, 223

NOT APPLICABLE

EXCELLENT CONDITION

VERY GOOD CONDITION - no problems noted.

GOOD CONDITION - some minor problems.

SATISFACTORY CONDITION - structural elements show some minor deterioration.

FAIR CONDITION - all primary structural elements are sound but may have minor section loss, cracking, spalling, or scour.

POOR CONDITION - advanced section loss, deterioration, spalling, or scour.
