STRUCTURE EVALUATION SUMMARY

This concrete tee beam bridge is in good condition overall. Problems at this time include spalling with exposed rebar on the south column of the east pier, the south deck overhang in Span #2 near the east pier, and the west pier diaphragm beneath Beam #3; missing bridge rail end caps at the southeast, northeast, and northwest corners; and debris accumulation along the curblines which has clogged the deck drains along the south curbline. In addition, vegetation is growing from the base of several columns which is beginning to encroach the bridge.

The bridge is currently posted for 18 tons at both approaches; vegetation slightly obscures the signage at the northeast corner. It should be noted that the present load rating is sufficient for legal loads, and the bridge does not require posting. However, the bridge may continue to be posted at the discretion of the Park.

Corrective action should be taken as outlined in this report to prevent the possible development of more serious or costly problems in the future. Consideration should also be given to installing an approach guardrail system that meets current safety guidelines for traffic barriers.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5230-001P

A (Critical) - Structure is closed, in imminent danger of collapse, or presents a critical safety hazard.

B (Major) - Structure exhibits severe deterioration, presents a safety hazard, or is designated a high priority due to age and/or condition.

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. 5230-001P

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.
