STRUCTURE EVALUATION SUMMARY

This steel multi-beam bridge, which spans the walls of Lock 23, is in fair condition overall. The main problem is widespread paint failure with laminar rusting of the structural steel. The ends of the exterior beams are buried, holding moisture against the beams. If the beams are not repainted, this could lead to further section loss and an eventual reduction in load carrying capacity of structure.

Other problems include deterioration of the mortar joints in the lock walls with displacement of several stones and vegetation growing from several of the joints. In addition, the southwest rail post has decay at the connection with the deck and is loose and unstable under normal loadings. There is also decay of two timber deck planks and a full-height split in one timber deck plank; settlement at the east side of the north approach; and debris accumulation on the deck surface and the abutment bearing seats. It should be noted that the hold-down cable on the west side of the south abutment has been removed.

STRUCTURE SUMMARY STRUCTURE NO. 3100-036S

VIOLETTES LOCK BRIDGE #1 INSPECTION DATE. 12/08/2025

Since the previous inspection, new timber deck runners have been installed.

Corrective action should be taken as outlined in this report to prevent the possible development of more serious or costly problems in the future.

226 PRIORITY OF IMPROVEMENT C

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.
