STRUCTURE EVALUATION SUMMARY

This steel multi-beam bridge is in fair structural condition overall. The main problems include previously noted section loss on the steel beam bottom flanges and lower portions of the webs, and concrete deterioration with efflorescence and exposed rebar on the east fascia arch girder. The steel beams should be cleaned and spot painted to prevent further deterioration, and the exposed rebar on the east arch fascia girder should be cleaned and coated with an approved sealant.

Additional problems include moderate transverse cracking of the approach pavement and the bridge wearing surface, moderate delamination and spalling of the substructure concrete, and moderate cracking with efflorescence on the abutment backwalls.

It should be noted that the seawall adjacent to this structure and around the Tidal Basin continue to deteriorate, exhibiting extensive mortar loss throughout the masonry mortar joints, and numerous missing and displaced stones.

The seawall immediately to the southwest of structure is a safety hazard, the cap stone is undermined and could collapse under pedestrian load. The opening between the seawall and the west wingwalls has resulted in active erosion with significant soil loss from behind the seawall. Consideration should be given to a rehabilitating the seawall.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 3400-031P

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. 3400-031P

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.
