This bridge has a Poor overall condition rating of 1 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 40 vehicles per day and is 71 years old.
Its sufficiency rating of 15.4 places it below the national average of 63.6.
The NBI records a navigation clearance of 19 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 302 feet long — a short crossing, about 10-15 seconds.
A truss bridge — the steel framework can provide a sense of enclosure.
About 19 feet above ground — moderate height, similar to a 3-5 story building.
Only about 40 vehicles cross daily — very light traffic with low congestion risk.
The deck is 20 feet wide with 1-2 lanes — a narrower crossing.
This bridge crosses over water. Focus on the road ahead — the water is far below.
This comfort score is designed to help individuals with bridge anxiety plan their travel. All bridges in the National Bridge Inventory are regularly inspected and deemed safe for travel. This is not medical advice — if you experience severe anxiety, please consult a healthcare professional.
