Truss bridges are characterized by their triangular truss structures, which form a series of interconnected triangles within the main load-bearing members. These trusses provide support and distribute forces efficiently across the bridge span.
The bridge span of a truss bridge can vary significantly depending on the specific design and requirements of the bridge. Longer bridge spans can be achieved by using additional truss members and enhancing the overall structural strength. Factors such as site conditions, traffic volume, and engineering considerations influence the determination of the bridge span.
It's important to note that the bridge span does not include the length of the approach roads or any additional structural elements beyond the main support piers. It solely refers to the distance between the main supporting components of the truss bridge itself.
