STRUCTURE EVALUATION SUMMARY

This fracture-critical steel girder bridge, which consists of both northbound and southbound structures, is in fair condition overall. The main problems are minor to moderate deterioration of the substructure concrete and the retaining walls which has progressed since the last inspection and widespread minor cracking and isolated delamination and spalling of the concrete wearing surface. The substructure and retaining walls should be repaired in order to prevent further concrete deterioration, and the wearing surface should be repaired and sealed to halt water intrusion.

Another issue at this time is the reformation of surface rust on the girder and stringer ends at the abutments, which is exacerbated by the leaking expansion joints. These joints should be resealed as necessary, and the girder and stringer ends should be repainted.

Other problems include clogged deck drains and isolated loose stones in the masonry guardwalls. Also, minor section loss on the structural steel superstructure occurred prior to repainting with a few locations rusted through;

however, the section loss does not affect the structural integrity. Repairs should be made as outlined in this report to prevent the possible development of more serious or costly problems in the future.

It should be noted that the approaches have been repaved and the lane markings have been repainted since the last inspection.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 3300-001P

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.

FIELD INSPECTION REPORT STRUCTURE NO. 3300-001P

G = GOOD (CODES 7 - 9) F = FAIR (CODES 5 - 6) P = POOR (CODES 0 - 4)

CONDITION RATING CODE EQUIVALENTS FOR SUB-ELEMENTS

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.

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

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.
