Long-span corrugated-metal buried structures are generally defined as conduits constructed of structural plate with spans exceeding 15 ft to 25 ft (4.6 m to 3.7 m). The principal applications for long-span structures are culverts and grade separations, with many installations serving as alternatives for small bridges. The paper summarizes a comprehensive survey of the state-of-the-art of the design and construction of these long-span structures. Among the aspects considered for these conduits are the design concepts, construction procedures, economic considerations, experimental investigations, and failures. Conditions imposed during construction of the long-span structures are major factors governing design. The use of proper construction procedures is vital. Most of the long-span structure failures, which have occurred either during construction or in service, have resulted from improper construction or backfill material. /ASCE/
