Description 

This is thought to be Vermont's first bridge made out of concrete, albeit for pedestrian use (the first concrete highway bridge wouldn't be until a 1902 culvert). It formerly had a companion span to the west that has long since been demolished

Nice discovery. There are some small, unassuming bridges out there with strong significance. Looks can be deceiving.

Curious if aggregate is river rounded or crushed. Anecdotally river gravel concrete around here holds up better than more modern crushed.

Never would've guessed that this was any sort of significant, having driven by it more times then I can count. Turns out its (as far as anyone can tell) the first concrete bridge to have been built in VT. And a pre-1900 concrete bridge as well makes it a rare find. I'll have to document it the next time I'm in that area!
