STRUCTURE EVALUATION SUMMARY

This weathering steel beam bridge is located on Forge Creek Road, which is currently posted for a 5 ton weight limit.

This structure is in fair condition overall. The main problem with this bridge is the poor drainage due to the debris accumulation on the deck. Other problems include severe rutting of the deck; a missing object marker at the northeast bridge corner; decayed and loose northwest reflective object marker post; trees growing at the base of the north wingwalls and an erosion hole behind the northeast wingwall; and debris and soil accumulation on the bearing seats and along the bottom flanges of the beams.

This bridge is scheduled for replacement in the near future under Project GRSM 14(3), 112(1).

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5460-034P

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.
