The Short Line Bridge is a truss bridge that spans the Mississippi River in Minneapolis, Minnesota, United States. It was originally built in the 1880s and upgraded a few years later by Chicago, Milwaukee, St. Paul and Pacific Railroad and was designed by American Bridge Company .
A fracture critical bridge is a bridge or similar span that is vulnerable to collapse of one or more spans as a result of the failure in tension of a single element. While a fracture critical design is not considered unsafe, it is subject to special inspection requirements that focus on the tension elements of its structure.
The deck is flexible and lies on the main cables, which are anchored to the earth. Underspanned suspension bridge: an early 19th-century descendant of the simple suspension bridge. The deck is raised on posts above the main cables. Stressed ribbon bridge: a modern descendant of the simple suspension bridge. The deck lies on the main cables, but ...
In steel construction, steel cables may be used due to their great resistance to tension (although they cannot take any load in compression). The common uses for cross bracing include bridge (side) supports, along with structural foundations. This method of construction maximizes the weight of the load a structure is able to support. It is a ...
A segmental bridge is a bridge built in short sections (called segments), i.e., one piece at a time, as opposed to traditional methods that build a bridge in very large sections. The bridge is made of concrete that is either cast-in-place (constructed fully in its final location) or precast concrete (built at another location and then ...
Rigidity is the property of a structure that it does not bend or flex under an applied force. The opposite of rigidity is flexibility.In structural rigidity theory, structures are formed by collections of objects that are themselves rigid bodies, often assumed to take simple geometric forms such as straight rods (line segments), with pairs of objects connected by flexible hinges.

The omission of the expansion joint removes a pathway for the penetration of chloride-bearing road salts to the bridge's sub-structure. In the United Kingdom there is a presumption that most new short to medium length bridges will be of the integral type. [citation needed] An early example of an integral bridge is masonry arch bridge.
