STRUCTURE EVALUATION SUMMARY

This steel multi-beam bridge, which spans the walls of Inlet Lock 2 at Lock 23, is in fair condition overall. The main problem is widespread deterioration of the paint with laminar rusting and section loss from the steel beams. The ends of the exterior beams are also buried, holding moisture against the beams. If the beams are not cleaned and repainted, the section loss could lead to an eventual reduction in the load-carrying capacity of the 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; deterioration of the timber deck planks and bridge rails; and debris accumulation on the deck surface and the abutment bearing seats. It should also be noted that the hold-down cable on the west side of the south abutment has been severed.

Since the previous inspection, new timber runner planks have been installed and gravel has been placed at the south approach.

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

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 3100-037S

VIOLETTES LOCK BRIDGE #2 INSPECTION DATE : 12/08/2025

PRIORITY OF IMPROVEMENT 226

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.

SATISFACTORY CONDITION - structural elements show some minor deterioration.6

FAIR CONDITION - all primary structural elements are sound but may have minor section loss, cracking, spalling, or scour.

POOR CONDITION - advanced section loss, deterioration, spalling, or scour.4

SERIOUS CONDITION - loss of section, deterioration, spalling, or scour have seriously affected primary structural components. Local failures are possible. Fatigue cracks in steel or shear cracks in concrete may be present.

CRITICAL CONDITION - advanced deterioration of primary structural elements. Fatigue cracks in steel or shear cracks in concrete may be present or scour may have removed substructure support. Unless closely monitored it may be necessary to close the structure until corrective action can be taken.

“IMMINENT” FAILURE CONDITION - major deterioration or section loss present in critical structural components or obvious vertical or horizontal movement affecting structure stability.
