STRUCTURE EVALUATION SUMMARY

This prestressed concrete multi-girder bridge is in poor condition overall. The main problem is widespread cracking and delamination of both pier caps, with heavy efflorescence present; this is a serious condition which could affect the bearing seats and lead to a loss of load capacity if not repaired in the near future. Other problems include cracking with moderate to heavy efflorescence and numerous popouts on the deck underside, likely due to alkali-silica contamination; a lack of sealant in the expansion joints; widespread cracking and spalling of the curbs and railings;

moderate to severe cracking of the asphalt wearing surface over the abutments and piers and at the approach slab ends; debris and vegetation growth along the curblines; and a tree growing out of a weep hole at the north abutment.

Repairs are not required at this time, as the structure is programmed for replacement under Project NATR 1E10 with an anticipated completion date in 2015.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5570-004P

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.
