STRUCTURE EVALUATION SUMMARY

This concrete frame bridge is in good condition overall. The main problem is deterioration of the parapet mortar joints, which has resulted in detachment and rotation of multiple parapet corner sections. Other problems include displaced capstones at the west side wingwalls; misalignment of the southeast reflective object marker and the vertical clearance sign at the west underpass approach; graffiti obscuring the reflective object markers at the west underpass approach; and vegetation obscuring the reflective object markers at the east underpass approach.

Additional problems include vine and vegetation growth on the east side wingwalls; vegetation growth through the parapet mortar joints; an area with exposed rebar due to insufficient concrete cover along the east face of the deck slab; and several voids with exposed rebar on the deck underside near the roadway centerline.

It should also be noted that the reflective object markers do not properly define the roadway limits. Since the previous inspection, a “ONE LANE BRIDGE” sign has been installed at the west underpass approach and reflective object markers have been installed at the east underpass.

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. 5140-195P

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. 5140-195P

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.
