STRUCTURE EVALUATION SUMMARY

This precast segmental concrete bridge is in good condition overall, with only minor problems at this time. These include cracking of the pintle and bottom slab of the box girder at the north abutment, and shifting of the bridge laterally toward the east and south at the south abutment. The structure appears to have shifted an additional inch over the west bearing at the north abutment, but no distress to the structure or the bearing pad was noted at this time.

The structure will continue to be monitored for movement.

The main problem is the moderate cracking and deterioration of the wearing surface over the deck and approach slabs. The continued deterioration of the wearing surface has resulted in a rough ride across the structure.

Additional problems include deterioration of the drainage troughs under the expansion joints, a detached curb near the south abutment, and some missing hardware on the bridge railing system. Rusting of steel plates at anchorage blocks was noted and is ongoing, resulting in the spalling of grout blocks at several anchorage locations; while no repairs for this condition are currently deemed necessary, the situation will continue to be monitored. Consideration should also be given to installing guardrail terminations that meet current AASHTO guidelines.

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. 5140-182P

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.

FIELD INSPECTION REPORT STRUCTURE NO. 5140-182P

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.
