STRUCTURE EVALUATION SUMMARY

This "bobtail" cantilever concrete box girder bridge is in generally good structural condition, but exhibits some problems that require attention. These problems include widespread minor deterioration of the deck concrete, which can allow water to penetrate into the box girder; and an ongoing loss of approach embankment under the end of the bridge. The deteriorated concrete deck should be removed, and the deck protected with a concrete overlay. Some erosion control measures have been installed under the bridge ends, however the erosion and the embankment loss continues and will be monitored during future inspection cycles. Consideration should be given to construction of concrete slabs at the approaches to better distribute traffic loads.

The bridge is scheduled for rehabilitation under Project WA NPS NOCA 20(1). Work will include sealing the concrete deck, replacing the south approach pavement, and repairing undermining at the approach.

Other minor problems include debris and embankment against the side of the concrete box girder at the northeast corner and minor erosion of the approach shoulder at the northwest end.

It should be noted that replacement of this one-lane bridge with a two-lane structure has been under consideration for some time. Replacement is warranted based on the expected increase in traffic due to the newly constructed visitor center, as well as future improvements and additions to the Newhalem campground facility. If the replacement bridge is not constructed, however, corrective measures should be taken as outlined in this report to help prevent the possible development of more serious or costly problems.

STRUCTURE SUMMARY

STRUCTURE EVALUATION SUMMARY CONTINUED

It should also be noted that this structure has been designated as being "scour-critical". However, appraisal of actual scour conditions was inhibited by swift current and debris present at the upstream face of piers. It is recommended that the piers be periodically inspected by the NPS for scour during periods of minimal flow discharge from the dam located upstream.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 9470 015P

226 PRIORITY OF IMPROVEMENT C

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.

(*Includes typical contract costs for mobilization, traffic control, and design/construction engineering; but does not include detour bridges, work beyond the bridge limits, or work not listed above. Estimates are approximate and are for preliminary planning purposes only; they should not be used as a complete or final engineers estimate.)

REMARKS: Cost estimates assume that the recommended actions will be combined with similar work being performed on other structures.

Bridge may be replaced in the near future; recommendations only apply if bridge is not replaced.

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

N

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.

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.
