STRUCTURE EVALUATION SUMMARY

This large continuous steel girder bridge is in fair condition overall, and requires a high degree of maintenance. All primary structural elements are in satisfactory condition. The paint on the structural steel superstructure remains adequate, except in Span #1. In this location, the top coat of paint is peeling off; however, the primer coat remains intact. The main structural problem is widespread cracking (up to 1/16" wide) of the deck underside with numerous areas of spalling with exposed rebar, moisture leakage, and moss growth. Additionally, moderate cracking with heavy efflorescence, delamination, and spalling with exposed rebar is present on Pier Caps #18 and #21. Several of the other pier caps, as well as the stems, have minor areas of exposed rebar due to insufficient concrete cover, and nearly all of the pier caps have some minor cracking with efflorescence. Another area of concern in the substructure is the moderate honeycombing on the stems of Piers #14 and #22 and moderate cracking of several piers near the waterline. The deck expansion joints are loose at several locations with the sliding plate at Pier #28 heavily impacting under traffic load; many of the bolts securing the expansion joints are missing which has also caused vertical misalignment of the plates.

Other problems include widespread deterioration of the paint on the bridge railings with several areas of moderate rust; minor settlement and moderate cracking of the approach pavement; random areas of delamination and spalling with exposed rebar on the deck surface, curbs, parapets, and abutment slabs; several loose metal curb guards;

moderate accumulation of gravel along the curblines; and a lack of object marker tape on the parapet ends.

The Structure Evaluation Summary is continued on the following page.

STRUCTURE EVALUATION SUMMARY CONTINUED

Also, the utility conduits at the base of the abutments have rusted through, exposing the wires; however, the navigation lighting appears to be solar powered.

It should be noted that the channel soundings at the upstream end of Piers #16, #17, and #20 were significantly less than previous measurements dating back to 2007. This could be attributable to flood debris underwater, and will be monitored during future underwater and routine inspections.

Repairs should be made 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. 5570-028P

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.

FIELD INSPECTION REPORT STRUCTURE NO. 5570-028P

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.

STRUCTURE EVALUATION SUMMARY

This large continuous steel girder bridge is in fair condition overall, and requires a high degree of maintenance. All primary structural elements are in satisfactory condition. The paint on the structural steel remains adequate, except in Span #1 near the south abutment. In this location, the paint is peeling off of the exterior faces of the girders, and has smaller areas of failure on the interior structural members and bearings. The main structural problem is widespread cracking (up to 1/16" wide) of the deck underside with numerous areas of spalling with exposed rebar above the stringers and along the girder bolsters. Addition problems include moderate to severe cracking with some exposed rebar on Pier Caps #18 and #21. Several of the other pier caps have minor areas of exposed rebar, and nearly all of the pier caps have some minor cracking with efflorescence. Another area of concern in the substructure is the moderate honeycombing on Piers #14 and #22 and moderate cracking of Pier #3 near the waterline.

Other problems include widespread deterioration of the paint on the bridge rail with several areas of moderate rust, moderate settlement and cracking of the approach pavement, minor areas of exposed rebar along the parapets, several loose metal curb guards, moderate accumulation of gravel along the curblines, and missing reflective object marker tape at the parapet ends. It should also be noted that the east channel marker light is not functioning, and there is a utility conduit at the base of the north abutment which has rusted through, exposing the wires. Since the previous inspection, the roadway striping has been repainted on the deck and approach roadway.

Corrective action 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. 5570-028P

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.

(*Includes typical contract costs for mobilization, traffic control, and design/construction engineering; but does not include detour bridges, work beyond the bridge limits, or work not listed above. Estimates are approximate and are for preliminary planning purposes only; they should not be used as a complete or final engineers estimate.)

REMARKS: Cost estimates assume that recommended actions will be combined with similar work being performed on other structures.

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 ac ion.

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.
