This bridge has a Poor overall condition rating of 4 out of 9. This bridge is classified as being in poor condition, meaning one or more structural components have significant deterioration. Poor condition does not mean the bridge is unsafe to drive on, but it does mean repairs or replacement may be needed.
The bridge carries 52 vehicles per day and is 115 years old.
Its sufficiency rating of 40.1 places it below the national average of 63.6.
The NBI records a navigation clearance of 16 feet — the minimum vertical space below the bridge deck. The total height of the bridge structure (including towers, railings, and superstructure) may be higher.
