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, widespread minor to moderate cracking and isolated delamination and spalling of the concrete wearing surface, and minor to moderate erosion of the north channel bank at the structure due to stream migration. The substructure and retaining walls should be repaired in order to prevent further concrete deterioration, the wearing surface should be repaired and sealed to halt water intrusion, and the erosion of the north channel bank should be mitigated with the installation of engineered riprap.

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. 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 several bearings at the piers have been retrofitted in the past due to a lack of anchor bolts.

Also, the northbound approaches and the right lane of the southbound approaches have been repaved and the lane markings have been repainted since the last inspection.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 3300-002P

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.
