STRUCTURE EVALUATION SUMMARY

This steel multi-beam bridge is adjacent to the Parkway and is used primarily by local traffic including equipment for a working farm and gravel trucks from a nearby quarry. The bridge is in fair condition overall. The main problem is that the bearings at the piers are fixed, and do not allow for movement at the piers which has resulted in spalling of the pier caps in the past. The bearings should be retrofitted or replaced to allow for thermal movement of the superstructure. Concrete repairs have cracked full depth. The condition of these caps will continue to be monitored.

Additional problems include: heavy corrosion of the flanges and webs of the piles near the waterline with up to .125" of section loss on the flange tips at the north pile bent; fallen trees in the channel at upstream and downstream from the structure; an object marker that has been knocked down at the northeast corner; vegetation growth that is encroaching the roadway from underneath the north span, and obscuring the object markers at the northwest, southwest and southeast corners. The H-piles should be scheduled for encasement in the near future. Corrective action should be taken 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 there is a high volume of loaded dump trucks from the quarry that use the bridge.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5140-203P

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

9 EXCELLENT CONDITION

8 VERY GOOD CONDITION - no problems noted.

7 GOOD CONDITION - some minor problems.

6 SATISFACTORY CONDITION - structural elements show some minor deterioration.

5 FAIR CONDITION - all primary structural elements are sound but may have minor section loss, cracking, spalling, or scour.

4 POOR CONDITION - advanced section loss, deterioration, spalling, or scour.

3 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.

2 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.

1 “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.

0 FAILED CONDITION - out of service; beyond corrective action.
