Structural Moves - Steel Truss Bridges
Truss bridges are the oldest style of modern bridge technology, boasting more than thirty
different styles of truss. While timber truss bridges (like the Cataract Falls Covered Bridge) were the most common in the early to mid-1800s, steel
beams started to replace timber and iron beginning in the 1880s. As a plus, truss bridges are pillars of
efficiency and economy, as they make great use of the building material.
