STRUCTURE EVALUATION SUMMARY

This concrete frame bridge is in fair condition, primarily due to deterioration of the original and widened structural concrete on the south side. Rehabilitation of the north half of the bridge (westbound lane) took place during 2015.

Approximately 4' of the north face of the bridge and parapet had been repaired. The northern 3' of asphalt wearing surface was removed and prepped for paving.

Problems include widespread deterioration with exposed rebar at the junction between the original and widened portions of the frame; rutting of the asphalt wearing surface from tire action; and sloughing of the channel banks.

Additional problems include a missing object marker, faded roadway striping, vegetation encroaching on the structure, and paved over (plugged) deck drains along the south curb.

It should also be noted that this bridge has been designated as "Scour Critical" based on a 1999 hydraulic study. The calculated scour depth is lower than the bottom of the pier footings. While no significant scour was observed at the abutments or piers, it is recommended that the structure be checked for any visible effects of scour immediately following major flood events.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 1430-031P

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.

FIELD INSPECTION REPORT STRUCTURE NO. 1430-031P

G = GOOD (CODES 7 - 9) F = FAIR (CODES 5 - 6) P = POOR (CODES 0 - 4)

CONDITION RATING CODE EQUIVALENTS FOR SUB-ELEMENTS

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 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.

FAILED CONDITION - out of service; beyond corrective action.

CONDITION RATING CODES FOR ITEMS 58 - 62, 222, 223

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.
