STRUCTURE EVALUATION SUMMARY

This painted steel multi-beam bridge is in fair to poor condition overall. Problems include differential settlement and cracking of the concrete abutments; the movement has also resulted in a small fracture directly under the upstream exterior beam at the west abutment. The settlement will be monitored during future bridge inspections. In addition, it is not known if the abutments contain any steel reinforcement. It should be noted that the top portions of the upstream wingwalls are delaminated, and that the wingwalls appear to lean toward the stream.

Other problems include widespread deterioration of the paint on the structural steel, with minor rusting present. It should also be noted that scour along the channel bottom has undermined the concrete apron at both abutments.

STRUCTURE SUMMARY STRUCTURE NO. 6320-001P

MINERS RIVER BRIDGE INSPECTION DATE: 09/22/2021

In view of the high cost of rehabilitation, the ongoing scour issue, the age of the structure, and the projected substantial increase in visitor traffic, it is recommended that this bridge be replaced in the near future. The new bridge could be longer and rest on foundations located beyond the existing abutments, which would then serve as retaining walls; this approach would substantially mitigate the environmental concerns associated with removing the abutments. Please be advised that the load rating of the bridge has been reduced due to the deterioration of the abutments, but the structure does not require posting for a weight restriction at this time.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 6320-001P

MINERS RIVER BRIDGE INSPECTION DATE : 09/22/2021

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.
