Not just
a bridge, my friend, but the longest and tallest trestle bridge in New England back in the day --- torn down, unfortunately. around 1923 just after the abandonment of the New Haven's Shelburne Falls branch. And yes, remnants of it can be found; in fact, a footbridge has recently been built using the piers in the river that supported the original bridge. Also nearby, crossing under the westerly abutment (which still stands), is the ROW of the Conway Electric Railroad trolley, most of which is now a road, winding its way down a steep hill to the site of the former Conway railroad station and across the Deerfield River to site of another depot on the B&M. The whole thing is a fascinating place to visit.
Google "South River Trestle Conway Massachusetts" and you'll find pictures of the bridge.
Here's a link to more recent photos of the spot:
