STRUCTURE EVALUATION SUMMARY

This prestressed concrete beam bridge is in fair condition overall. The main problems include widespread deterioration of the concrete elements, as well as deterioration of the asphalt wearing surface and rusting of the bearing devices. The wearing surface should be replaced with a new overlay. In addition, the areas of spalling and delamination in the deck underside, curbs, and superstructure should be repaired and the cracks in the abutment breastwalls, bearing seats, and backwalls should be sealed to prevent water intrusion. Finally, the anchor bolts for the bearing assembly for Beam #2 at the north abutment are corroded and should be replaced, and all of the bearing devices should be cleaned and painted to arrest section loss.

It should also be noted that a 13" long x up to 5" wide area of loss of bearing is present at Beam #1 bearing at the south abutment due to a spall in the bearing seat.

The previously noted wingwall rotation has not increased since the previous inspection and will continue to be monitored during future inspections.

Repairs should be made as outlined in this report to prevent the possible development of more serious or costly problems in the future. If corrective action is not taken, the deterioration will continue to progress and may eventually lead to loss of load capacity.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 3450-009P

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:

FIELD INSPECTION REPORT STRUCTURE NO. 3450-009P

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.
