STRUCTURE EVALUATION SUMMARY

This steel girder bridge is in good condition overall. The main significant change in the structural condition since the previous inspection is a deteriorating mortar pad for the bearing of Girder #2 in Span #3 at Pier #3 which, if not repaired, may result in a loss of bearing for the girder.

The bridge and approaches were repaved with asphalt in 2008. The paving operation left the bridge deck expansion joints packed with asphalt. The drainage system for the expansion joints is also clogged with asphalt and debris. The expansion joints and associated drainage system should be cleared of debris to allow for free expansion and contraction of the structure, and adequate drainage of the roadway surface.

Other main problems, which remain relatively unchanged from the previous inspection, include widespread paint failure on the structural steel with some minor rusting, erosion beneath Spans #1, #9 and #10, and heavy accumulation of flood debris in the channel at Pier #11. Repairs should be made 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. 5570-184P

226 PRIORITY OF IMPROVEMENT C

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 3 SERIOUS CONDITION - loss of section, deterioration, spalling, or scour have seriously affected primary structural components. Local failures are possible.

9 EXCELLENT CONDITION Fatigue cracks in steel or shear cracks in concrete may be present.

8 VERY GOOD CONDITION - no problems noted. 2 CRITICAL CONDITION - advanced deterioration of primary structural elements. Fatigue cracks in steel or shear cracks in concrete may be present

7 GOOD CONDITION - some minor problems. or scour may have removed substructure support. Unless closely monitored it may be necessary to close the structure until corrective action can be taken.

6 SATISFACTORY CONDITION - structural elements show some minor deterioration. 1 “IMMINENT” FAILURE CONDITION - major deterioration or section loss present in critical structural components or obvious vertical or horizontal 5 FAIR CONDITION - all primary structural elements are sound but may have movement affecting structure stability. Structure is closed to traffic but minor section loss, cracking, spalling, or scour. corrective action may return structure to light service.

4 POOR CONDITION - advanced section loss, deterioration, spalling, or scour. 0 FAILED CONDITION - out of service; beyond corrective action.
