The advantages of truss bridges is that it is economical, light, strong and uses short timbers. Greater strength with less material. Greater span (the distance between end points) than what most single beams. Easier to repair and maintain. Disadvantage can be wasted material if not designed properly. There can be no force members that do nothing for the structure.
Advantages: Very sturdy, can have several cracks in structure before breaking disadvantages: best for short distances, not attractive, hard to maintain

A Howe truss is a type of truss design characterized by its triangular framework, where the vertical members and diagonal members slope towards the center. The counter braces, which are typically placed in the opposite direction of the main diagonal braces, help to stabilize the structure by resisting compression forces and preventing buckling. To build a Howe truss with counter braces, engineers first construct the basic truss framework, then integrate the counter braces by connecting them at strategic points to enhance the overall strength and load distribution of the truss. This design is particularly effective in bridges and other structures where load-bearing efficiency is crucial.
