STRUCTURE EVALUATION SUMMARY

This concrete channel beam bridge is in fair condition overall. Problems include deterioration of Channel Beams #1, #4, and #5 including delamination, cracking with efflorescence, and spalling with exposed rebar. Other problems include undermining of the northwest retaining wall; scour exposing the north abutment and wingwall footings; a collapsed section of the drainage ramp at the southwest corner due to erosion; and rusted utility suspension cables and hardware attached to the channel beam stems along the east side of the bridge.

The previously noted scour along the north abutment is still present, but does not appear to have increased in severity since the last inspection. Consideration should be given to placing engineered riprap at the north wingwalls and north abutment to protect the footings and mitigate further scour.

The bridge is currently posted for 18 tons at both approaches; vegetation is beginning to obscure the signage at both approaches. 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 and height requirements for traffic barriers.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5230-002P

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.

CONDITION RATING CODES FOR ITEMS 58 - 62, 222, 223

N NOT APPLICABLE

9 EXCELLENT CONDITION

8 VERY GOOD CONDITION - no problems noted.

7 GOOD CONDITION - some minor problems.

6 SATISFACTORY CONDITION - structural elements show some minor deterioration.

5 FAIR CONDITION - all primary structural elements are sound but may have minor section loss, cracking, spalling, or scour.

4 POOR CONDITION - advanced section loss, deterioration, spalling, or scour.

3 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.

2 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.

1 “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.

0 FAILED CONDITION - out of service; beyond corrective action.
