STRUCTURE EVALUATION SUMMARY

This two-barrel culvert remains in poor condition. The main problem is site-related scour and undermining of the masonry wall footings with the most severe case of scour at the intermediate wall, where an 8' long void with full width undermining is permitting water to flow from the south barrel into the north barrel. In addition, the concrete footing is exposed throughout.

Other problems include deterioration of the masonry footings, debris and rock accumulation in the barrels, spalling with section loss on exposed rebar on the barrel ceiling, heavy vegetation growth adjacent to and on the west wingwalls, accumulation of drift at the upstream side, and pothole on the south approach pavement in the southbound lanes.

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.

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.
