STRUCTURE EVALUATION SUMMARY

This concrete frame bridge is in good condition overall with only minor problems. These problems include erosion at the east side wingwalls; and exposed rebar due to insufficient concrete cover on the deck slab underside and abutment breastwalls.

Since the previous inspection, the overpass and approaches have been resurfaced and restriped; the underpass approaches have been resurfaced; vegetation obscuring the southwest reflective object marker has been removed;

the additional reflective object marker at the northwest underpass has been removed; and the vertical clearance sign at the west underpass approach has been replaced. It should also be noted that the reflective object markers do not properly define the roadway limits.

Corrective action should be taken as outlined in this report to prevent the possible development of more serious or costly problems in the future. Consideration should be given to installing a railing system capable of meeting current safety and minimum height guidelines for traffic barriers.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5140-184P

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.

(*Includes typical contract costs for mobilization, traffic control, and design/construction engineering; but does not include detour bridges, work beyond the bridge limits, or work not listed above. Estimates are approximate and are for preliminary planning purposes only; they should not be used as a complete or final engineers estimate.)

REMARKS: Cost estimates assume that recommended actions will be combined with similar work being performed on other structures.

It should be noted that structure constricts underpass roadway to a single lane, presenting a safety hazard for motorists. For this reason, consideration should be given to replacing this bridge with longer structure at an estimated contract cost of $700,000.

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.
