STRUCTURE EVALUATION SUMMARY

This steel bascule and concrete arch bridge is a vital link between Virginia and W ashington, D.C., carrying an extremely high amount of vehicular and pedestrian traffic across the Potomac River daily. The structure is in poor condition overall due to continuing problems related to corrosion of the steel in the bascule span, deterioration of the concrete in the arch spans, and deterioration of the sidewalks and wearing surface. It should be noted that an in-depth inspection of the entire superstructure and an underwater inspection of the substructure were performed earlier this year.

The bascule span no longer functions as a movable structure. W hile there is generally moderate corrosion of the steel throughout the bascule span, more severe corrosion, including areas where the steel is entirely rusted through, is present in the stringers and associated framing supporting the fixed portion of the sidewalks and the edges of the roadway over the bascule span abutments. The interior trunnion posts also exhibit significant section loss.

Temporary repairs to critical supporting members for the sidewalks in the fixed portions of the bascule span have been accomplished through the installation of temporary pedestrian bridges over the sidewalk portion of these areas.

Additional temporary repairs to the concrete deck, to the concrete bearing seats along the back edge of both bascule abutments, to the retrofit steel columns, and to the steel stringers under the curbs in the bascule span have recently been completed. In addition, several sections of the sidewalks have been replaced, and the west approach has been patched. However, it must be stressed that these are considered only short-term repairs, and a more extensive project will be required to ensure the structure remains adequate for the longer term.

STRUCTURE EVALUATION SUMMARY CONTINUED

(Continued on next page)

It is recommended that the bascule span be replaced or rehabilitated in the near future. In addition, replacement of the concrete deck is recommended, as are repairs to the deteriorated portions of the abutments, piers, and concrete arches. These areas continue to be problematic and subject to deterioration, primarily in areas adjacent to the deck expansion joints. Planning and preliminary design of a comprehensive project to improve the bridge for the long-term is currently in progress.

It should also be noted that, at the time of inspection, repairs were being made to a section of the south railing in Span #10 that had sustained severe collision damage.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 3300-016P

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. 3300-016P

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.
