STRUCTURE EVALUATION SUMMARY

This steel multi-beam bridge is in fair structural condition, but has problems with scour and undermining, the extent of which is outlined below. Severe decay of the south timber fascia in the east span has caused the timber sidewalk above to be temporarily closed until repairs are complete. Other deficiencies include decay of the remaining fascia timber; deterioration of the mortar joints in the abutment breastwalls, bearing seats, and pier walls; and several locations of collision damage to the steel railing. Additional defects noted were missing rail sleeves; loose bolts at the rail posts; minor curb spalls; and a 14" drop-off at the west end of the south sidewalk.

It should also be noted that this structure has been deemed "scour critical", i.e. calculations from a 1998 scour study indicate the bridge foundations may be susceptible to undermining and instability during a major flood event. An additional scour evaluation was performed in 2015, and recommended installing additional engineered riprap in front of both abutments and around the piers, as well as monitoring the foundations for scour following major flood events.

It should be noted that the substructure footings are founded on timber piling. During this inspection, the abutment footings (pile caps) were exposed full length with up to 8" of undermining. Undermining of the northeast wingwall footing is present, and extends back for approximately 2'. Scour is present at the piers, with up to 5' of the footing (pile cap) exposed at the downstream end of the east pier. An underwater inspection performed in August 2018 further detailed the location and extent of the scour and its effects.

STRUCTURE EVALUATION SUMMARY CONTINUED

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. 8800-002P

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.

PRELIMINARY ESTIMATE TOTAL* :

(*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: It is recommended the south sidewalk be temporarily closed until repairs to sidewalk are complete

It is recommended that bridge foundations be monitored for scour following major flood events.

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

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.
