STRUCTURE EVALUATION SUMMARY

This post-tensioned concrete box girder bridge is in good condition overall. No repairs are required at this time.

This bridge has not yet been opened to public traffic. Construction of the bridge railings was in progress during the inspection. Minor issues, including debris in the expansion joints, vegetation growth on the west approach parapets/wingwalls, and trees growing against the north deck overhang should be addressed when final preparations are made to open this portion of the Foothills Parkway. Additional problems to be monitored include map cracking of the deck surface over the piers; areas of spalling with exposed rebar on the deck underside over the south cheekwalls at both abutments; and several areas of hairline diagonal and horizontal cracking in the box girder webs.

It should be noted that the black paint applied on the exterior side of the box girder and the underside of the deck overhangs hinders the visual identification of cracks.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5460-210P

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

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 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.

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