Megaprojects require care in the project development process to reduce any possible optimism bias and strategic misrepresentation. Examples of megaprojects include bridges, tunnels, highways, railways, airports, seaports, power plants, dams, wastewater projects, Special Economic Zones (SEZ), oil and natural gas extraction projects, public buildings, information technology systems, aerospace projects, and weapons systems.
This list identifies a wide variety of examples of major historic and contemporary projects that meet one or both megaproject criteria identified above.
