-
A.
truss bridge
A truss bridge is a type of bridge whose load-bearing superstructure is composed of a framework of interconnected triangular units that efficiently distribute forces through tension and compression.
-
B.
steel arch bridge
A steel arch bridge is a structure that uses a curved steel arch as its main load-bearing element to span a distance and support traffic above.
-
C.
wrought-iron bridge
A wrought-iron bridge is a structure for spanning physical obstacles, such as rivers or roads, whose primary load-bearing elements are made from wrought iron, valued historically for its toughness, malleability, and resistance to fatigue.
-
D.
cast-iron bridge
A cast-iron bridge is a structure whose primary load-bearing elements are made from cast iron, typically featuring modular, prefabricated components assembled to span a gap such as a river or roadway.
-
E.
iron bridge
