STRUCTURE EVALUATION SUMMARY

This concrete slab bridge is in poor condition overall. The main structural problem is deterioration of the concrete deck slab, with severe cracking, delamination, spalling with exposed steel reinforcement, and heavy efflorescence present along the sides of the slab.

Other problems noted include spalling of the north pier; deterioration of the stone masonry mortar joints in the abutment breastwalls and wingwalls; and settlement and cracking of the asphalt pavement at both ends of the bridge.

Site-related problems include migration of the channel toward the north; as a result, debris and sediment has collected in the south and center spans. Other issues include scour at the upstream end of the piers, and sloughing of the channel banks at both ends of the north abutment.

It should also be noted that the bridge railing system does not meet current safety requirements for traffic barriers.

This bridge is scheduled for replacement in the near future under Project BLRI 2A16.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5140-077P

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.

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

N NOT APPLICABLE 3 SERIOUS CONDITION - loss of section, deterioration, spalling, or scour have seriously affected primary structural components. Local failures are possible.

9 EXCELLENT CONDITION Fatigue cracks in steel or shear cracks in concrete may be present.

8 VERY GOOD CONDITION - no problems noted. 2 CRITICAL CONDITION - advanced deterioration of primary structural elements. Fatigue cracks in steel or shear cracks in concrete may be present

7 GOOD CONDITION - some minor problems. or scour may have removed substructure support. Unless closely monitored it may be necessary to close the structure until corrective action can be taken.

6 SATISFACTORY CONDITION - structural elements show some minor deterioration. 1 “IMMINENT” FAILURE CONDITION - major deterioration or section loss present in critical structural components or obvious vertical or horizontal 5 FAIR CONDITION - all primary structural elements are sound but may have movement affecting structure stability. Structure is closed to traffic but minor section loss, cracking, spalling, or scour. corrective action may return structure to light service.

4 POOR CONDITION - advanced section loss, deterioration, spalling, or scour. 0 FAILED CONDITION - out of service; beyond corrective action.

CONDITION RATING CODE EQUIVALENTS FOR SUB-ELEMENTS
