For travelers with bridge anxiety
This bridge may cause some awareness for travelers with bridge anxiety, but has manageable characteristics.
This bridge is 290 feet long — a short crossing, about 10-15 seconds.
A truss bridge — the steel framework can provide a sense of enclosure.
About 81 feet above ground — an elevated crossing, similar to a 5-10 story building.
About 31,000 vehicles cross daily — moderate traffic, some congestion possible.
The deck is 32 feet wide with 1-2 lanes — a narrower crossing.
This bridge crosses over land, not water — no water views 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.
