STRUCTURE EVALUATION SUMMARY

This bridge is in fair structural condition due to extensive cracking of the concrete deck and superstructure, as well as spalling and scaling of abutment concrete. In addition, some limited delamination and spalling with exposed rebar is present on the superstructure. Moderate erosion is present along the south abutment breastwall and wingwalls, with minor undermining of the south abutment evident. It should also be noted that the approach railing system itself is considered functionally obsolete due to insufficient rail height, strength, and stiffness. Corrective action should be taken as outlined in the inspection report to prevent more serious or costly problems from developing in the future.

This structure is scheduled for repairs in the near future under Project PRA-ANTI 300(1), 900(2).

With corrective action as outlined in this report, and regular maintenance, a useful life of approximately 30-35 years can be expected for this structure under current loading conditions.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 3120-001P

226 PRIORITY OF IMPROVEMENT C

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.

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

N

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.

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.
