This bridge's days may be numbered. According to information from locals, the county is looking into plans to remove the entire bridge sometime within the next year or two for liability reasons. When visiting the bridge, I noticed that access to the structure has been sealed off with fences and the removal of the approaches although some people have constructed a make-shift ladder to get onto the bridge. In either case, visit this bridge while it's still there for it may not be there for long.....

Apparently, I can't promote my pictures above the ones previously posted. That must be a webmaster-only thing.

I prefer the modern to the historical.

I've just posted photos from Monday (Memorial Day) of this bridge viewed from both ends. Is it preferable to have a current picture, or the historical photo, as the "thumbnail" for this bridge?

(Not pushing to have mine moved up. Just curious.)

Yeah........should have gleaned through the report to confirm that Massillon was involved, although I was pretty confident they were.

If you read the HAER documentation it lists the Toledo-Massillon Bridge Company, successor to Massillon Bridge Company as bridge fabricator.

Looks as if Massillon might have supplied the trusses for this bridge......as it features their distinctive plaques.
