For travelers with bridge anxiety
This bridge may cause some awareness for travelers with bridge anxiety, but has manageable characteristics.
This bridge is 76 feet long — a quick crossing, under 5 seconds at highway speed.
A truss bridge — the steel framework can provide a sense of enclosure.
No height data available — likely a standard overpass height.
Only about 100 vehicles cross daily — very light traffic with low congestion risk.
The deck is 14 feet wide — a very narrow, single-lane 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.
