Wilson Pratt Truss Bridge was created in 1904.
Caleb and Thomas Pratt invented the truss bridge in 1844. Some of the materials that have been used in truss bridges are timber, steel, reinforced concrete, and iron.
The pratt truss is efficient because the longer diagonal members are in tension and the shorter vertical members are in compression. Members in tension fail because the member is stressed to materials maximum stress capacity. Members in compression usually fail through buckling because of instability long before the materials maximum stress is reached.
you can check this out link below- its about Truss Bridges

As far as i can tell there are 27 different types of truss bridges (i.e. Brown truss, Bowstring truss, Kingpost truss, Long truss, and Pratt truss). Hope this helps :D

I am looking for something that's about 173k in price
it is a hybrid between an arch bridge and truss bridge. so it is classified as an arch and truss
Warren truss bridge
Glenville Truss Bridge was created in 1885.
