What is the avergae span of a truss bridge What to what IE 40 meters to 1000 meters?

Answer 1

The average span of a truss bridge typically ranges from about 20 meters to 200 meters, depending on its design and intended use. Smaller truss bridges, such as those used for pedestrian or light vehicle traffic, often have spans around 20 to 40 meters. Larger truss bridges, especially those designed for heavy traffic or railways, can span up to 200 meters or more, with exceptional cases reaching around 300 meters. However, spans exceeding 300 meters are less common and often require specialized engineering solutions.
