I grew up swimming in the river that flowed under this Viaduct. We would jump off the Concrete structure, but around 2013 they filled the pond in with cement.. No one ever told us there was a 19th century bridge there. We all assumed it was just a giant mound of sand. The expanse is mind boggling and it took a LONG time to get down to the bottom of that hill.

You have painted a rather humorous picture in my mind :^)

No worries. I came across it while doing a category search so I thought I'd ask.

I might have been half-asleep when I made the edit, because I can't figure out how I'd have thought this was a post truss either...

I did a category search on Post trusses and this bridge came up. I'm not sure how this is a Post truss. To me, it looks like the South American viaduct built by Phoenix that incorporates the Fink trusses (minus the multi-panel Finks of course). I didn't want to change it in case I'm missing something.

That said, it is absolutely amazing that the entire 1870's structure, Phoenix Columns and all, remains intact under a gigantic mass of fill!
