This bridge has a Fair overall condition rating of 5 out of 9. While it is not classified as structurally deficient, it shows some deterioration that is being monitored.
The bridge carries 22,000 vehicles per day and is 109 years old.
Its sufficiency rating of 60.2 places it below the national average of 63.6.
The NBI records a navigation clearance of 55 feet — the minimum vertical space below the bridge deck. The total height of the bridge structure (including towers, railings, and superstructure) may be higher.
For travelers with bridge anxiety
This bridge may cause some awareness for travelers with bridge anxiety, but has manageable characteristics.
This bridge is 495 feet long — a short crossing, about 10-15 seconds.
A truss bridge — the steel framework can provide a sense of enclosure.
