STRUCTURE EVALUATION SUMMARY

This concrete open-spandrel deck arch is in fair to good condition overall. However, there are three areas of moderate to severe delamination and spalling with exposed rebar on the west arch rib, two of which are over traffic and present a traffic hazard. These locations should be repaired immediately. There are additional areas of minor delamination and spalling throughout the arch ribs, struts, and spandrel columns, which should be repaired in the course of regular maintenance.

In addition, widespread cracking of the deck underside with efflorescence is indicative of likely water intrusion through the deck concrete. The deck surface should be sealed to prevent further intrusion and slow the rate of deterioration of the concrete.

Other non-structural problems include moderate erosion of the south abutment slope with an exposed footing at the west column of Bent #1, and heavy vegetation and vine growth on the arch ribs and spandrel columns. Repairs should be made as outlined in this report to prevent the possible development of more serious or costly problems in the future.

It should be noted that the lane markings have been restriped since the previous inspection.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 3300-010P

A (Critical) - Structure is closed, in imminent danger of collapse, or presents a critical safety hazard.

B (Major) - Structure is seriously deficient or presents a safety hazard, but can remain in service at reduced loads or with frequent inspections.

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. 3300-010P

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 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.

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.
