they really did build the bridge
civil engineers, structural engineers, and architects are the main bridge builders.
Steel bridges take a long time to build because of the precision of the work. The pieces have to fit perfectly together, or else the bridge will not be safe.
Bridges are almost invariably built from steel due to its high structural strength, flexibility and relatively low cost.
