STRUCTURE EVALUATION SUMMARY

This prestressed concrete box beam bridge is in good structural condition and has only minor problems at this time. These include cracking and delamination of the abutment backwalls, and hairline cracking on the sides of several box beams. No repairs to the cracks are needed at this time, but these conditions will continue to be monitored during future inspection cycles.

Problems requiring attention include minor to moderate decay of several approach guardrail posts; an accumulation of debris on the bearing seats and along the deck edges; cracking of the asphalt pavement at the west approach; re-opening of the previously sealed pavement crack at the east abutment; and several loose utility line connections.

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.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 1540-001P

PADDOCK CREEK BRIDGE INSPECTION DATE : 08/20/2019

PRIORITY OF IMPROVEMENT226

A (Critical) - Structure is closed, in immediate damage of collapse, or presents a critical safety danger.

B (Major) - Structure is seriously deficient or presents a safety hazzard, but can remain open 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. Preventive maintenance may be required.

E (Special) - Structure is under construction or reconstruction.
