STRUCTURE SUMMARY STRUCTURE NO. 4290-029P

BLACKS POINT BRIDGE INSPECTION DATE: 06/12/2023

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.

The replacement of 12 glulam deck timbers, tightening and replacement of missing beam splice bolts, pile bracing replacement, and FRP pile jacket installation are scheduled to be completed under Project COLO 1C14, 1D48, and 1E15. Therefore, no recommendations or project costs are included for these elements.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 4290-029P

BLACKS POINT BRIDGE INSPECTION DATE : 06/12/2023

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.
