Has anyone checked out the Blaine Hill Bridge? It was on the old national road in Blaine OH. I happened to see another bridge in the shadow of the US 40 bridge on google maps.

There are a couple of images on Goog:

This bridge isn't listed on the S bridge page:

The current US 40 viaduct was built in 1933:

Also in this pic you can see the 1933 viaduct has also been rehabilitated:

I've been to it a couple times and the Wheeling roadgeet meet I hosted a couple years ago stopped at it. I have photos at https://www.flickr.com/photos/bmpowell/sets/72157606128746475.
I went down there. It's not the most scenic of the older bridges, as there's a bunch of stuff all over it now to make it look pretty and neighborhoody. You do get some nice views of the "newer" bridge above it.
