What is a "truss bridge"?

A truss bridge is a type of bridge that uses a framework of triangular shapes to support the structure. This design helps to distribute weight evenly, making the bridge strong and stable. Truss bridges are often made from materials like steel or wood and can span long distances, making them suitable for both roadways and railways.

Truss bridges are commonly seen in various settings, including highways, railroads, and pedestrian walkways.
