STRUCTURE EVALUATION SUMMARY

This prestressed concrete multi-girder bridge is in fair condition overall. The main problems include widespread delamination and spalling with section loss to exposed rebar in the abutment breastwalls and delamination and spalling of the girder ends and end diaphragms with section loss to exposed rebar and prestressing strands. In addition, Girder #7 (south exterior girder) over the northbound lanes of Clara Barton Parkway has delamination and spalling with section loss to two exposed prestressing strands due to past collision damage.

Due to the redundant nature of this structure, the spall on Girder #7 is not considered sufficient to reduce the load rating or the expected life of the bridge. The top of the west abutment backwall has moderate spalling and is allowing water to spill onto the structure below, accelerating deterioration of the concrete and rusting of the bearings. The west pourable sealant at the west expansion joint is severely deteriorated and the strip seal at the east expansion joint is filled with debris.

Other problems include snowplow damage to the east expansion joint assembly, deterioration of paint on the railings, three cracked rail post base plate welds, missing nuts on bearing anchor bolts, deterioration of sealant for granite curbs, and faded pavement markings.

Corrective action should be taken 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. 3300-032P

A (Critical) - Structure is closed, in imminent danger of collapse, or presents a critical safety hazard.

B (Major) - Structure exhibits severe deterioration, presents a safety hazard, or is designated a high priority due to age and/or condition.

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 sec ion 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.
