There's actually three Ohio Bridge companies, all different. "Directory of American Bridge Building Companies 1840-1900" by Victor Darnell gives these two:

* Ohio Bridge Co. - of Cleveland (1869-1874) - may also have operated as Rezner, Stone and Co.

* Ohio Bridge Co. - of Toledo (1896-1901)

In modern times, there's also the Ohio Bridge Corp., which started in 1952 building polygonal Warren trusses. This company is also known as U.S. Bridge, not to be confused with other firms that have been called U.S. Bridge.

To disambiguate between the three Ohio companies, I've created these categories:

* Ohio Bridge Co. of Cleveland

* Ohio Bridge Co. of Toledo

* Ohio Bridge Corp.

Note that the name of the town should be written as part of the name so the system can keep them separate (don't put the town in parentheses).

Is there no relation between Ohio Bridge Co. of Cleveland and of Toledo? If so, we need James Baughn to come up with a solution to fix the conflict with the builder names. Using proper syntax, the two builders get stuck together.

Okay John......need a clarification on this one.

This is a 3-span Rezner design bowstring, and my understanding was that the trusses (which would include the Bowstring upper chords) had been taken down and stored for reuse.

Are you saying something to the contrary here?

removed by city of beacon despite bridge's listing on nationnal register.. bridge truss's "stored" at transfer station. Nothing done to preserve bow string truss pieces
