Question

Simple examples of these structures can be incrementally launched. Joseph B. Strauss pioneered the “bascule” type of these structures and assisted in the construction of one of these non-vehicular structures that provides a textbook example of aero·elastic flutter. (20[1])Scour holes are dug around these structures’ (*) abutments. Little falsework is used when building these structures with (10[1])the cantilever method. In one type (10[1])of these structures, fan-shaped "stays" distribute compression throughout the deck and girders. The distance between these structures' supporting piers is their span, which is maximized by their “suspension” type. For 10 points, name these structures used to drive across rivers. ■END■

ANSWER: bridges [accept suspension bridges or bascule bridges; prompt on piers or abutments or arches or girders until they are respectively read by asking "what larger structures do they support?"] (Aeroelastic flutter caused the collapse of the Tacoma Narrows Bridge nicknamed “Galloping Gertie.”)
