STRUCTURE EVALUATION SUMMARY

This prestressed concrete multi-beam bridge is in fair structural condition due to widespread vertical cracking of the concrete piles. To help prevent further deterioration, which could lead to an eventual loss of load capacity, the piles should be sealed to prevent saltwater from entering the cracks. Therefore it is recommended that the cracked areas of the piles be protected with a flexible jacketing system as outlined in this report.

Further problems include widespread minor cracking and deterioration of the deck surface, which should be sealed to prevent the intrusion of runoff and road salts into the concrete. Additional repairs should be made to the deteriorated areas of concrete on the underside of the beams and bent caps to prevent the intrusion of salts from channel spray.

These and other 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 also be noted that the timber approach guardrails are in poor condition and do not meet current AASHTO standards for traffic barriers. These guardrails should be replaced in the interest of public safety.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 4190-001P

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.

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.
