STRUCTURE EVALUATION SUMMARY

This double barrel corrugated steel plate arch culvert is in fair condition overall, but exhibits some deterioration. Problems include cracking and spalling of concrete patch repairs previously made to the headwalls; widespread spot corrosion of the steel barrels, with small holes rusted through the barrels in places;

and a minor loss of galvanizing on the barrel flutes where exposed at ends. Horizontal cracking in the flutes of the east barrel pier wall near the south end spring line bolts and minor crimping one foot below the spring line at the north end of both barrels was recently observed and should be monitored. In addition, there is a heavy accumulation of tumbleweeds in the upstream channel with scour holes at the upstream toe wall and at the gabion check dams.

No corrective measures for the headwalls or barrels are deemed necessary at this time, but the condition of these elements will continue to be monitored during future inspection cycles. The tumbleweeds should be removed and engineered riprap should be installed at toe wall and in scour holes.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 7400-004P

GALLO WASH BRIDGE INSPECTION DATE : 05/18/2022

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 hazard, 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.
