Thanks luke.There are composite metals that are used in all kinds of applications.I forgot about wood and metal as in bridges.
Dana is correct. When trusses are referred to as "combination" or "composite", they're referring to the mixed use of timber and metal parts.
You have a good point there,Dana and Kay.Didn't look at it that way.Thanks.
Believe it may refer defer to composite of wood and metal probably Iron. Will defer to more knowledgeable pontists for definitive answer.
I have a question.I see the word composite used in the pictures of this bridge.I've dealt with composite metals in the past.Is this bridge made out of composite materials?From what I remember composite metals are more than one metal.
It seems like this railroad built multiple wooden truss bridges- there is another that is abandoned farther down the line. Who knows, there may have been even more than these two! https://bridgehunter.com/va/cumberland/cartersville/
Is this a rare wooden railroad truss? It certainly seems to to me!
Your dates and chronology on the Eagle Rock bridges are in need of research and correction. The current bridge was a replacement for the bridge closed in 1985 -- and constructed on the same site. All of the iron truss bridges, with the exception of the Phoenix Bridge (which remains open to automobile traffic), were closed to all traffic by the 1960s.
