STRUCTURE EVALUATION SUMMARY

This continuous concrete tee beam bridge is in fair condition. The main problem with the structure at this time is the collision damage with broken concrete rail posts in the east railing. This damage compromises the strength of the railing and reduces its ability to redirect an errant vehicle where it to be struck again. To help improve motorist safety, the damaged railing and rail posts should be replaced.

Other problems include heavy accumulation of drift on the channel banks, in the channel, and against the pier columns as well as moderate channel bank erosion which threatens the stability of several trees. The accumulation of drift has contributed to the formation of minor scour holes at the piers and blocks normal stream flow.

Additional problems include minor spalling with exposed rebar in the deck underside and underside of the beams, minor deterioration of the wearing surface along the centerline and west edge, cracking of the asphalt approach pavement, settlement of the approach shoulders, and the paved over deck expansion joints.

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.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5140 015P

226 PRIORITY OF IMPROVEMENT C

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.
