STRUCTURE EVALUATION SUMMARY

This steel multi-beam bridge is in fair condition overall. Rehabilitation work was completed on this structure in 2011 under Project PRA-COLO 1A18 and Project PRA-COLO 1B35, including cleaning and repainting of the steel superstructure and rehabilitation of the substructure concrete.

The beam ends at the abutments exhibit moderate pitting predating the paint. Additional loss of section has been halted by the cleaning and painting of the beams; however, the bottom flanges at the abutments and at Pier #6 likely were not cleaned properly and are exhibiting some minor surface rusting. This condition should be monitored during future inspections to determine if spot painting is necessary in the future.

Additional problems include minor deterioration of the compression joint seals and adhesion failure throughout the pourable seal expansion joints over the abutments, minor widespread cracking of the deck surface and underside, shifted elastomeric bearing pads at the west abutment and Pier #1, and isolated areas of minor delamination throughout the pier caps, columns, and abutments. This structure is scheduled for rehabilitation under Project No.

COLO 1B37, 1D46. The scope of this project includes repair of all deteriorated concrete on the piers, deck underside and abutments, repair the sagging utility conduit, reseal the expansion joints at the abutments, and replace the compression seal joints over the piers.

Corrective measures should be taken as outlined in this report to prevent the possible development of more serious or costly problems in the future.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 4290-012P

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.

FIELD INSPECTION REPORT STRUCTURE NO. 4290-012P

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 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.

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.
