STRUCTURE EVALUATION SUMMARY

This concrete slab bridge is in fair structural condition due to concrete deterioration throughout the underside of the structure. There are minor to moderate cracking and spalling with exposed rebar at several locations on the slab underside and exterior sides, and at the bent caps bearing seats particularly at Bents #15 and #33. Several piles present moderate scaling and section loss at the water level. Concrete repairs have been made in the past to the deck underside, curbs, railings, and substructure. However, these repairs have areas of cracking and are delaminated or spalled at isolated locations.

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

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.
