STRUCTURE EVALUATION SUMMARY

This prestressed concrete multi-girder bridge is in fair condition overall. Though not observed during this inspection due to dry conditions, there is evidence of heavy leakage through the deck expansion joints onto the superstructure and substructure components below; these joints should be cleaned and resealed to prevent further leakage onto the structure below deck. Additionally the asphalt wearing surface exhibits minor to moderate widespread longitudinal and map cracking and should be replaced in the near future.

Other problems include, erosion of the abutment slopes, an exposed footing at the west column of the north pier, vine and other vegetation growth on the structure, and clogged deck drains. In addition, there are several areas of minor spalling with exposed rebar, including on the bottom flange of Girder #1 at the south abutment, on the north and east faces of the east column in the north pier, and on the wingwalls. It should also be noted that the deck drains do not extend beyond the bottom flange of the girders and several appear to drain in close proximity to some of the pier bearings; the drains should be extended to prevent further leakage onto the structural elements below.

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. 5140-040P

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.
