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 76,300 vehicles per day and is 34 years old.
Its sufficiency rating of 46.0 places it below the national average of 63.6.
The NBI records a navigation clearance of 155 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
