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 bascule span was being conducted at the time of this inspection. Since the inspection, the structural load rating has been revised, the right lane in both directions has been closed over the bascule span, and the bridge has been posted for a 10 ton load limit
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.

STRUCTURE SUMMARY STRUCTURE NO. 3300-016P
STRUCTURE EVALUATION SUMMARY CONTINUED
An additional emergency contract has been awarded, is scheduled to begin this later this summer. The scope of work consists of strengthening of the structural steel (including gusset plate replacement), repairs to the sidewalks and deck, shoring of the concrete floor beams. 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.
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, temporary barriers were in place at 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.
