This bridge has a Fair overall condition rating of 6 out of 9. While it is not classified as structurally deficient, it shows some deterioration that is being monitored.
The bridge carries 12,412 vehicles per day and is 71 years old (reconstructed in 1990).
Its sufficiency rating of 64.1 is above the national average of 63.6.
The NBI records a navigation clearance of 85 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 has some features that may be challenging for travelers with bridge anxiety. See the tips below for a more comfortable crossing.
This bridge is 3380 feet long — an extended crossing, several minutes.
A truss bridge — the steel framework can provide a sense of enclosure.
About 85 feet above ground — an elevated crossing, similar to a 5-10 story building.
About 12,412 vehicles cross daily — moderate traffic, some congestion possible.
The deck is 30 feet wide with 1-2 lanes — a narrower crossing.
