STRUCTURE EVALUATION SUMMARY CONTINUED

This painted steel multi-girder bridge is in fair condition overall. Other problems include widespread cracking with efflorescence throughout the underside of the concrete deck and overhangs, as well as diagonal (shear) cracking of the pier cap, and minor rusting of the bearings and paint deterioration along the exterior girder lower flanges. These problems may be exacerbated by leakage through the deck, and it is therefore recommended that the bituminous wearing surface be replaced. In addition, the areas of rusted steel should be cleaned and spot painted. Other corrective measures should be performed as outlined in this report to prevent the possible development of more serious or costly problems in the future.

A small crack previously noted in a longitudinal stiffener on the north exterior girder does not appear to have propagated further since the last inspection. The crack is located at a welded butt joint in a compression zone, and was probably a result of shrinkage of the filler metal during the welding process when the girders were fabricated. No repairs to the crack are deemed necessary, but this condition will continue to be monitored.

The failed sliding plate anchorages on both the east and west ends have been repaired the last inspection. However, the sidewalk-curb cover plate at the southwest corner of the joint has completely detached and should be repaired.

It should also be noted that, based on the results of the 1998 scour study, the bridge is considered scour-critical, i.e.

the calculated scour depth resulting from a 500-year flow could theoretically result in a loss of stability for the spread footing at the pier. Although no scour countermeasures are deemed necessary at this time, it would be prudent to monitor the structure during and immediately after major floods for signs of scour around the pier footing.

FIELD INSPECTION REPORT STRUCTURE NO. 8400-001P

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.
