STRUCTURE EVALUATION SUMMARY

This concrete frame bridge is in fair condition overall. The main problem is concrete deterioration and collision damage at the southwest, northwest, and northeast wingwalls. Other problems include a lack of “TUNNEL AHEAD” and “ONE LANE” signs at the east underpass approach; exposed and rusting rebar due to insufficient concrete cover on the abutment breastwalls and deck underside; and soil and debris accumulation in the weepholes at the abutments restricting proper drainage.

Since the previous inspection, the southwest reflective object marker and vertical clearance sign at the west underpass approach have been replaced; potholes have been repaired in the underpass roadway and approaches;

and the roadway and approaches have been resurfaced and restriped. It should also be noted that the reflective object markers do not define the roadway limits.

Corrective action should be taken as outlined in this report to prevent the possible development of more serious or costly problems in the future. Consideration should be given to installing a railing system capable of meeting current safety and minimum height guidelines for traffic barriers.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5140-189P

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.

Consideration should be given to installing a railing system capable of meeting current safety and minimum height guidelines for traffic barriers.

FIELD INSPECTION REPORT STRUCTURE NO. 5140-189P

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.
