STRUCTURE EVALUATION SUMMARY

This concrete tee-beam bridge is in fair condition overall due to widespread active leakage through the deck and widespread deterioration of the structural concrete. The bridge is scheduled for repairs in the near future under Project PRA-NAMA 17(1).

Please note that there are electrical lines throughout the structure interior, primarily in the east approach spans, as well as electrical equipment in the southeast corner of the structure interior, with "4000 Volts" painted on the wall. The electrical lines and equipment that are not in use should be removed and those that are in use should be protected in order to increase access and safety for inspection personnel. This and other maintenance items should also be performed as outlined in this report to prevent the possible development of more serious or costly problems in the future.

It should also be noted that the structure is currently posted for a 12'-11" vertical clearance on the right shoulder of the underpass roadway before Arlington Memorial Bridge (Structure No. 3300-016P) and 13'-1" on the right shoulder of the north approach. The posting located south of the structure is the actual measured clearance for that lane, and makes no allowance for vehicle bounce. Consideration should be given to re-posting the vertical clearance for 12'-9" at the south side of the structure to allow for vehicle bounce.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 3400-030P

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 the recommended actions will be combined with similar work being performed on other structures.

Structure is scheduled for repairs in the near future under Project PRA-NAMA 17(1).

Consideration should be given to re-posting the vertical clearance for 12'-9" at the south side of the structure to allow for vehicle bounce.

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 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.

0 FAILED CONDITION - out of service; beyond corrective action.

STRUCTURE EVALUATION SUMMARY

This continuous concrete tee-beam bridge is in fair condition overall due to widespread active leakage through the deck and widespread deterioration of the structural concrete. The concrete continues to deteriorate and water intrusion should be arrested by removal of the existing wearing surface and installation of a waterproofing membrane and a new wearing surface. The areas of unsound concrete throughout the structure should be repaired, and the exposed rebar cleaned and coated with an approved sealant. In the short term, the deck drains should be cleaned to prevent water ponding. It should be noted that there is one area of delamination on the underside of the arch that presents a pedestrian hazard. This should be addressed in the short term as well.

It should be noted that there are electrical lines throughout the structure interior, primarily in the east approach spans, as well as electrical equipment in the southeast corner of the structure interior, with "4000 Volts" painted on the wall.

The electrical lines and equipment that are not in use should be removed and those that are in use should be protected in order to increase access and safety for inspection personnel.

Summary continues on next page.

STRUCTURE EVALUATION SUMMARY CONTINUED

Since the last inspection, the underpass sidewalks paved with asphalt have been recast and the pedestrian railings removed. The structure has been reposted for 12'-11" vertical clearance on the right shoulder of the underpass roadway before Arlington Memorial Bridge (Structure No. 3300-016P) and 13'-1" on the right shoulder of the north approach. It should be noted that the posting south of the structure is the actual measured clearance for that lane.

Consideration should be given to reposting the vertical clearance for 12'-9" at the south side of the structure to allow for vehicle bounce. Additional repairs should be made as outlined in this report to prevent the possible development of more serious or costly problems in the future. If corrective action is not taken, the deterioration will likely continue to progress and may eventually lead to loss of load capacity.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 3400-030P

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.
