I do not have any photo's handy but can add them later.
That St. Marys bridge is in used today an is not 'completely' a lost structure.
Most of it has been taken down but part of is use to take car and foot traffic to the near by island called Middle Island.
The Silver Bridge is listed in Mason County, WV and Gallia County, Ohio. As far as I know, the bridge has always been listed that way, since the eastern landing of the Silver Bridge was in Point Pleasant, Mason County, West Virgina.
There is precious little information, that I've been able to find anyway, about the bridge at St. Marys that was of similar design to the Silver Bridge. In the essay on the Silver Bridge page, there is reference to the St. Marys bridge closing shortly after the collapse of the Silver Bridge. It was demolished in 1971.
If you have any information about that bridge, especially photographs of it, please send them to us so we can document this lost structure.
The Silver Bridge is listed, but it was in Mason County, not Pleasants County. Its page is http://www.bridgehunter.com/oh/gallia/silver/
The bridge I don't see listed here is its near-clone, which was on or near the site of the bridge shown here that was closed and demolished almost immediately after the failure of the Silver Bridge.
I couldn't understand why there are no pictures of the Silver Bridge at Point Pleasant that collapsed in 1967 on this site.
This photo is NOT the St. Marys Bridge. This photo is of the New Martinsville Bridge, which is about 25 miles north of the St. Marys Bridge. In the foreground is the Hannibal Locks & Dam, located at the New Martinsville Bridge.
