STRUCTURE EVALUATION SUMMARY CONTINUED

This bridge provides access to Fort Pulaski from U.S. Route 80. The bridge was constructed in 1938 and underwent rehabilitation projects in 1965, 1996, and 2008. The superstructure is comprised of 62 composite timber/concrete "corduroy" spans, and one steel beam span over the main channel. The substructure units (pile bents) are each comprised of 5 timber piles with a timber or concrete beam cap. The existing concrete/timber composite deck is part of the original 1938 construction. The bridge is currently posted for weight restrictions.

Several measures have recently been taken to keep the bridge operating in a satisfactory manner. Extensive structural repairs were made to the substructure in 2008 under Project PRA-FOPU 10(2). The scope of work for the repair project included replacement, splicing, and/or jacketing of a number of timber piles that had exhibited significant deterioration, and replacement of deteriorated cross-bracing members. Since the previous inspection, a new horizontal timber brace has been installed on the south face of Bent #32. In addition, the rails and curbs have been painted.

However, serious problems with the bridge persist, including extensive decay of the timber decking adjacent to the concrete bent caps, where many of the deck timbers and timber shims have lost bearing. In addition, the steel beams and bearings in the main span are exhibiting widespread rusting with substantial section loss in some key locations, and deterioration of the remaining unjacketed pile timber is rapidly progressing. It should also be noted that the existing riprap on the embankment slopes is undersized and gradually washing away, and the concrete bank protection is partially undermined. Due to the age of the structure, the widespread deterioration, and high cost of continued repairs, the bridge has been scheduled for replacement in FY 16 under Project PRA-FOPU 10(3).

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 5420-001P

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.

REMARKS: Bridge is scheduled for replacement in FY 16 under Project PRA-FOPU 10(3).

Bridge was repaired in 2008 under Project PRA-FOPU 10(2). South approach has been reposted for the original 18T-22T-34T load limit, reflecting the current Inventory Ratings for the H, Type 3, and Type 3S2 trucks respectively.

North approach remains posted for 18 tons.

Maintenance cost estimate is based on historical data, including costs for similar projects when available.

FIELD INSPECTION REPORT STRUCTURE NO. 5420-001P

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.
