STRUCTURE EVALUATION SUMMARY

This structure is a glue-laminated timber deck panel bridge. The structure is currently in fair condition overall, but exhibits some problems that require attention. These include weathering and deterioration of the timber deck; a large split in the deck at the northeast corner under the curb, causing the railing to lean outward; deterioration of the deck joint sealer at both abutments; and moderate scour along the east abutment. Corrective measures should be taken as outlined in this report to help prevent the possible development of more serious or costly problems in the future.

It should be noted that the bridge meets state legal load standards and does not require posting of load limit signs.

However, the bridge may be posted at the discretion of the Park to control the type of vehicle that accesses the facility. Options for such signing have previously been furnished to the Park.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 3130-001P

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.

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 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.

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