STRUCTURE EVALUATION SUMMARY

This prestressed concrete continuous multi-girder bridge is in fair condition overall. Problems noted include widespread moderate to severe cracking with heavy efflorescence on the east side of Pier Caps #1 and #5, and moderate to severe cracking with efflorescence and spalling of the east deck overhang over the piers. Additional problems include cracking and spalling of the curbs and railings at the expansion joints, cracking, delamination and spalling of the closure diaphragms at Piers #2 and #4, cracking of the wearing surface, and moderate debris accumulation at the upstream side of Piers #2 and #3. Moderate to heavy vegetation growth is also present beneath the bridge.

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

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5570-002P

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.

REMARKS: Structure is programmed for rehabilitation under Project NATR 1E10 with scheduled completion in 2015.

FIELD INSPECTION REPORT STRUCTURE NO. 5570-002P

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.
