The design and construction of such bridges. A truss bridge is a bridge whose load-bearing superstructure is composed of a truss a structure of connected elements usually forming triangular unitsThe connected elements typically straight may be stressed from tension compression or sometimes both in response to dynamic loadsThe basic types of truss bridges shown in this article have simple designs which could.
