STRUCTURE EVALUATION SUMMARY

This prestressed concrete multi-girder bridge is in fair condition overall. It appears that one or both of the abutments may have rotated toward the center of the bridge at some time in the past, forcing all of the spans closer together.

This apparent movement is evidenced by closure of the expansion joints and spalling in the rails, curbs, and deck overhangs, as well as damage to the bearing devices and anchor bolts at the abutments. This condition will continue to be monitored during future inspections.

Another problem is leakage through the expansion joints. Cracks in the asphalt wearing surface over the joints allow water to flow down onto the superstructure, contributing to the corrosion of the bearing devices. Deck expansion joints should be installed and the roadway repaved to help prevent further deterioration.

Other problems include spalling with exposed rebar on the deck underside at spot locations; minor diagonal cracking at the beams from the end diaphragms corners; cracking and deterioration of the concrete particularly at the underside of the pier caps due to excessive moisture; cracking, settlement, and undermining of the north abutment slope protection; and minor collision damage to the girders and some columns.

It should be noted the previous erosion along the west end of the south abutment and along the wingwall with minor exposure of the abutment footing has been repaired since the last inspection.

Corrective measures should be taken as outlined in this report to help prevent the possible development of more

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5570-135P

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.

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

N NOT APPLICABLE 3 SERIOUS CONDITION - loss of section, deterioration, spalling, or scour have seriously affected primary structural components. Local failures are possible.

9 EXCELLENT CONDITION Fatigue cracks in steel or shear cracks in concrete may be present.

8 VERY GOOD CONDITION - no problems noted. 2 CRITICAL CONDITION - advanced deterioration of primary structural elements. Fatigue cracks in steel or shear cracks in concrete may be present

7 GOOD CONDITION - some minor problems. or scour may have removed substructure support. Unless closely monitored it may be necessary to close the structure until corrective action can be taken.

6 SATISFACTORY CONDITION - structural elements show some minor deterioration. 1 “IMMINENT” FAILURE CONDITION - major deterioration or section loss present in critical structural components or obvious vertical or horizontal

5 FAIR CONDITION - all primary structural elements are sound but may have movement affecting structure stability. Structure is closed to traffic but minor section loss, cracking, spalling, or scour. corrective action may return structure to light service.

4 POOR CONDITION - advanced section loss, deterioration, spalling, or scour. 0 FAILED CONDITION - out of service; beyond corrective action.
