I am completely convinced that the installation at this site is not original. If these trusses are old they were likely moved to this location. More research needed.

Only reason I ask, is I wonder if it was built as part of some old, perhaps long-lost wealthy estate or something. Might shed light onto when it was built, assuming it was originally built here.

This has been one of those "little" bridge I drive by from time to time. I have had it on my list for over a year to photograph it and when I saw it I knew that it was unique. At this time I have no further details but I shall make inquiries.

I have no idea if its really old (cast iron) or newer (cast steel) but this extremely rare bridge is similar in appearance to British iron arch bridges. A very rare find.

How did you find the bridge? Do you know anything about the property or its owners? I would be curious why a bridge like this is located here.

What an interesting bridge! I'm curious to know why the bridge looks drawn up?

Hard to say for sure Craig...but sure looks like a good possibility. Definitely a unique little bridge.

Spring Mountain Drive a second opinion please

I have posted this small bridge as cast iron. I would live some additional comments on these small arched trusses, the likes of which I have not seen often. I do not know the age of the bridge.
