STRUCTURE EVALUATION SUMMARY

This prestressed concrete multi-girder bridge is in fair condition overall, but has some problems that require attention.

Problems include severe erosion of the abutment slopes with severe undermining of the drainage chute at the south abutment, minor spalling with exposed rebar on several girders, clogged deck drains as well as debris in the curblines, and dislodged joint seal and backer rod at the deck joints over the abutments. The bearing pads are also excessively compressed at the abutments, but pose no structural implications at this time. This situation will continue to be monitored. Due to traffic volume on this section of the Parkway, consideration should be given to installing Type 3 reflective object markers at the parapet ends.

Corrective action should be taken as outlined in this report to prevent the possible development of more serious or costly problems in the future.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5140-121P

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

B (Major) - Structure is seriously deficient or presents a safety hazard, but can remain in service at reduced loads or with frequent inspections.

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.

REMARKS: Cost estimates assume that recommended actions will be combined with similar work being performed on other structures.

The bearing pads are moderately compressed, but pose no structural implications at this time. Their condition will continue to be monitored.

FIELD INSPECTION REPORT STRUCTURE NO. 5140-121P

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 section 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.
