STRUCTURE EVALUATION SUMMARY

This cantilever structure is in fair condition overall. The main problems are the asphalt patching, delamination, and spalling of the slab/roadway surface, and the areas of delamination and spalling in the underside of the cantilever slab. Since the last inspection, numerous areas in the slab/roadway surface have been patched with asphalt. Areas of loose concrete on the underside of the cantilever slab should be removed to improve safety for underpass traffic in the southbound lanes on Clara Barton Parkway.

Other problems include collision damage to the timber guardrail on the west side of the south approach, several sections of damaged aluminum railing on the west side of the north approach, cracking and deterioration of the approach pavement, areas of delamination and spalling in the retaining wall below the structure and in the parapet, and an accumulation of debris along the curblines.

The structure is posted for a minimum vertical clearance of 13'-3", and the actual minimum vertical clearance measured beneath the structure is 13'-4". Consideration should be given to revising the signage to accommodate for vehicle bounce.

Repairs to the slab are scheduled for the near future under Project GWMP 6(1), 7(2). Other problems should be addressed as outlined in this report prevent the possible development of more serious or costly problems in the future.

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 sec ion 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.
