STRUCTURE EVALUATION SUMMARY

This concrete frame bridge is in fair condition overall. Problems include cracking with efflorescence in the wingwalls and east side of the slab, several areas of delamination and spalling with exposed rebar in the abutment breastwalls, and a large tree growing at the base of the northeast wingwall.

Other problems include vegetation growth overhanging the wingwalls and approach rails, erosion along the curbs at the approaches and at end of the west wingwalls, and clogged drop inlets in the underpass approach roadway. In addition, the pavement over the structure and at the approaches exhibits some cracking which should be sealed to inhibit moisture intrusion and further deterioration.

Since the last inspection, the underpass approach roadways have been repaved.

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

FIELD INSPECTION REPORT STRUCTURE NO. 3300-031P

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.
