For travelers with bridge anxiety
This bridge may cause some awareness for travelers with bridge anxiety, but has manageable characteristics.
This bridge is 82 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.

The deck is 16 feet wide — a very narrow, single-lane crossing.
This bridge crosses over water. Focus on the road ahead — the water is far below.
