Definition: a truss bridge supported mainly by trusses
In architecture, a truss is a structure comprising of one or more triangluar units
constructed with straight members, whose ends are connected at joints referred to as "node".
The Truss Bridge design was used to construct Carpenter's Bluff Bridge. Truss bridges are one of the oldest types of modern bridges. A truss bridge is economical due to the effecient use of materials for construction. Due to the abundance of wood, early truss bridge construction would use carefully fitted timbers for members taking compression and iron rods for tension members. The bridge was normally constructed as a covered bridge to protect the structure.
