Megastructure is an architectural and urban concept of the post-war era, which envisions a city or an urban form that could be encased in a massive single human-made structure or a relatively small number of interconnected structures. In a megastructural project, orders and hierarchies are created with large and permanent structures supporting ...
The world's longest suspension bridges are listed according to the length of their main span (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge.

A megastructure is a very large artificial object, although the limits of precisely how large vary considerably. Some apply the term to any especially large or tall building. [1] [2] Some sources define a megastructure as an enormous self-supporting artificial construct. The products of megascale engineering or astroengineering are megastructures.
Nazi Megastructures is a documentary television series appearing on the National Geographic Channel and a spinoff of the broader Megastructures television series. The series also aired as Nazi Mega Weapons on PBS , and as WWII Mega Weapons .
The bridge received the 2006 Outstanding Structure Award from the International Association for Bridge and Structural Engineering. In 2006 the bridge was featured in an episode of Megastructures on the National Geographic Channel. In 2011 the bridge returned to TV in an episode of Richard Hammond's Engineering Connections.
The bridge was designed with a dual-hinged stiffening girder system, allowing the structure to withstand winds of 286 kilometres per hour (178 mph), earthquakes measuring up to magnitude 8.5, and harsh sea currents. The bridge also contains tuned mass dampers that are designed to operate at the resonance frequency of the
This episode reveals how several suspension bridge breakthroughs (The Iron Bridge, Menai Bridge, Niagara Bridge, Brooklyn Bridge, Golden Gate Bridge and Verrazzano-Narrows Bridge) made it possible to construct the 2-mile (3.2 km) long Akashi Kaikyō Bridge.
