STRUCTURE EVALUATION SUMMARY

This concrete frame bridge is in good condition overall. Problems include moderate deterioration of the parapet masonry mortar joints in some locations and minor to moderate transverse and longitudinal cracking of wearing surface and approach pavement.

Other problems include a spall with exposed rebar at west side of south abutment, missing reflective object markers and vertical clearance signs along the underpass roadway, and widespread graffiti on the abutment breastwalls.

Corrective measures should be taken as outlined in this report to help prevent the possible development of more serious or costly problems in the future. In addition, consideration should be given to reconstructing the bridge parapets to meet current safety standards.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5140 004P

226 PRIORITY OF IMPROVEMENT D

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

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.

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.
