Construction methods for steel truss bridges, though much refined, have not changed appreciably. Bridge construction gradually shifted priority from the railroad requirements to the highway requirements. This shift was accompanied by replacement of temporary timber trestles and rail-mounted derrick cars or locomotive cranes with steel falsework and derricks mounted on travelers or tower barges. Truss construction is divided into three types - simple, cantilever, and continuous. Procedures for each type are presented by describing major representative structures.
