STRUCTURE EVALUATION SUMMARY

This prestressed concrete box beam bridge is in fair to good structural condition, but has several issues that require attention. Problems with the box beams include spalling with exposed steel on the underside of Beam "B", and longitudinal cracking along the bottom chamfer of Beam "E".

Other problems noted include lack of attachment of the southeast approach guardrail at one post; rotated railing spacer blocks; a broken utility connection hanger at the east abutment; and separation of the gabion basket splice at the northeast corner of the bridge.

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. It should also be noted that the superstructure exhibits water leakage between several box beams. To address this, consideration should be given to installing a waterproof membrane over the structure as part of a future pavement replacement project.

STRUCTURE SUMMARY STRUCTURE NO. 1540-005P

There is an area of settlement and pavement failure at the west side of the north approach. Cracks in the pavement have been sealed, but this condition will continue to be monitored until it also can be addressed as part of a pavement project.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 1540-005P

SQUAW 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.
