STRUCTURE EVALUATION SUMMARY

This post-tensioned concrete segmental arch bridge is in good condition overall. Problems include vegetation growth overhanging the structure in Span #1; vine growth throughout the piers and lower portions of the arches; pigeon debris and excrement at numerous locations on both the structure exterior and interior; and debris in the finger-type expansion joints. In addition, there is cracking at numerous locations and isolated spalling throughout the concrete superstructure and substructure; displaced riprap at the north abutment exposing the footing; cracking and delamination of the abutment slabs and approach slabs; erosion at south end of south arch above north side of south thrust block with void; and loose and missing stones on the masonry wingwalls and approach guardwalls.

The Structure Evaluation Summary continues on the following page.

Since the previous inspection a pedestrian fence was installed on the parapet on both sides of the bridge, and

STRUCTURE SUMMARY STRUCTURE NO. 5570-463P

missing anchor bolt nuts have been replaced on the rails on both rails.

Ponding water is present inside the north pier and the north end of the south arch adjacent to the north thrust block. This ponding can be partially attributed to moisture that is entering the structure through the access hatches which do not provide a tight seal. However, it should be noted that the ponding water in the north end of the south arch was observed to increase by approximately 4 feet due to a single storm event, which indicates water is likely infiltrating from another source besides the access hatch on the underside of the arch. The ponding water should be removed from the structure interior, the access hatches should be replaced or retrofitted with tighter sealing doors, and the south arch should be monitored during future storms to locate any alternate sources of water infiltration in order to appropriately seal it.

Current evaluation of the bridge indicates overstress under design wind load at the joints of Segments 2A51, 2A52, 2A53, and 2A54 at the south end of the south arch adjacent to the south thrust block. At the time of inspection, no indication of cracking or opening of the joints between these segments was observed. Condensation is present at the south end of the south arch, with heavy efflorescence at the joint between 2A54 and the south thrust block. However, these segments are located below grade, and the resulting temperature differential is likely causing the condensation. Deficiencies in the concrete arch segments remain consistent with typical deficiencies noted elsewhere throughout the arches. This condition will continue to be monitored during future inspections.

In addition, there are isolated locations of grout voids in the tendons in the box girder, as evidenced by sounding with a hammer. These conditions, while not requiring remediation at this time, will continue to be monitored during future inspections.

Slippage has been reported in the past at the interface between the box girder and the elastomeric bearing pads, and between the bearings and the arches. At those locations, the outer edges of the upper plinths have either spalled off or have become delaminated. Many of the bearing pads themselves, as well as the pot bearings at the abutments, were contracted up to 3-1/2" at an ambient temperature of 65°F. Contraction of the pot bearings at the abutments remains consistent with previous inspections; however the condition of the bearings pads and the supporting concrete at other locations was not verified at this time; monitoring using an UBIV is recommended during the next inspection cycle.

Corrective measures should be taken as outlined in this report to help prevent the possible development of more serious or costly problems in the future.
