STRUCTURE EVALUATION SUMMARY

This precast segmental concrete box girder bridge is in good condition overall. The main problem is deterioration of the asphalt wearing surface on the deck and on the approach slabs, including buckling and widespread longitudinal, transverse, and map cracking throughout. Other problems include failure of the neoprene drainage troughs at both bridge ends, misaligned curb stones on the west side of Span #1 and Span #8, and missing and/or loose rail hardware at various locations.

The structure has experienced shifting at the abutments in the past and has some cracking in the pintle and bottom slab at the north abutment, both of which are examined at each inspection. No appreciable shifting has occurred since the previous inspection and no additional distress to the structure or bearing pads was noted. Rusting of the steel plates at various post tensioning anchorage blocks has caused cracking and spalling of the grout blocks at those locations. The severity of this condition does not appear to have increased since the previous inspection. Both of the above referenced items will continue to be monitored.

This bridge is scheduled for improvements in the future under Project PRA-BLRI 2H14.

Corrective action should be taken as outlined in this report to prevent the possible development of more serious or costly problems in the future.

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.
