List of megaprojects

This is a list of megaprojects, which may be defined as:

Projects that cost more than US$1 billion and attract a large amount of public attention because of substantial impacts on communities, the natural and built environment, and budgets.
Projects that are "initiatives that are physical, very expensive, and public".^[1]

Some examples 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.

Aerospace projects

Antonov An-225 was the longest and heaviest aircraft in service. Only one unit was ever completed.
Boeing B-29 Superfortress, the first nuclear bomber, which cost 50% more than the development of the bombs in the Manhattan Project.
Boeing B-52 Stratofortress, with six decades of service as a strategic nuclear bomber, it is one of the largest military aircraft ever built. Every other bomber produced in the US after the B-52 have been megaprojects; however, it has not been replaced nor will it be in the foreseeable future.
Boeing 2707 and Lockheed L-2000 supersonic aircraft projects, initiated in 1963 via a US government-funded competition to build the United States' first Supersonic Transport (SST), prototypes never built, ultimately canceled due to political, environmental and economic reasons in 1971.
Boeing 747, a wide-body commercial airliner first produced in 1970, often referred to by the nickname Jumbo Jet,^[2]^[3] is among the world's most recognizable aircraft with uses for long-distance passenger transport, cargo, the US President's official shuttle plane, and as NASA's Shuttle Carrier Aircraft.
Boeing 787, made in the United States with local and globally sourced parts, is the first major aircraft to be made largely out of composite materials.^[4]
Concorde, a supersonic passenger airliner, a product of an Anglo-French government treaty that combined the manufacturing efforts of Aérospatiale and the British Aircraft Corporation, first flown in 1969, Concorde entered service in 1976 and continued commercial flights for twenty-seven years.
Convair B-58 Hustler, an all-weather, high altitude supersonic bomber with a fixed delta wing and 4 engines. The Hustler was operational from 1960 to 1970 in the US Air Force's Strategic Air Command for the deployment of up to 5 gravity nuclear weapons.
Lockheed C-5 Galaxy was the largest and heaviest aircraft of any kind for over a decade (1970 to 1982). This military cargo plane was the first development program with a billion dollar cost overrun.^[5]^[6]
F-22 Raptor, a single seat, twin-engine fifth-generation fighter manufactured by Lockheed Martin that uses stealth technology.

Northrop Grumman B-2 Spirit, also known as the Stealth Bomber, a US heavy bomber with "low observable" stealth. Total program cost including development, engineering, and testing averaged $2.1 billion per aircraft in 1997.^[7]
KH-11 reconnaissance satellite, manufactured by Lockheed Corporation and launched between 1976 and 1990.
Rockwell B-1 Lancer, a supersonic bomber with a variable-sweep wing built in the 1980s as a strategic bomber. It has since acquired conventional and multi-role capabilities.
Tupolev Tu-144, the first supersonic transport aircraft, made by the Russian aircraft company Tupolev, first flown on 31 December 1968 and entered service on 26 December 1975.
Tupolev Tu-160, the world's largest and heaviest combat aircraft, the world's largest supersonic aircraft, and the largest variable-sweep aircraft ever built. (The North American XB-70 Valkyrie had a higher empty weight and maximum speed but never entered production.)

Disaster cleanup

While most megaprojects are planned and undertaken with careful forethought, some are undertaken out of necessity after a natural disaster occurs. There have also been a few human-made disasters.

The Chernobyl New Safe Confinement was built to enclose the #4 reactor that was destroyed in the Chernobyl disaster of 1986 (completed summer 2019^[8]^[9])
The Fukushima disaster cleanup is ongoing, and includes the removal of spent nuclear fuel stored at the site of the 2011 Fukushima Daiichi nuclear disaster.
Cleaning up the Deepwater Horizon oil spill, Exxon Valdez oil spill, and AZF chemical factory explosion were megaprojects.^[10]
Many hurricanes and typhoons have caused extensive damage and required large cleanup efforts, the largest of which included projects that targeted the damaged infrastructure. The list of costliest Atlantic hurricanes covers the ones in the Atlantic region, including Hurricane Katrina from 2005.
Many earthquakes (and resultant tsunamis) have caused enough damage to infrastructure that enormous projects were undertaken. The 1994 Northridge earthquake, the 2004 Indian Ocean earthquake and tsunami, and the 2011 Tōhoku earthquake and tsunami are some of the most notorious and recent events that led to a megaproject.
Flooding is the cause of many disasters. Some have caused enough damage that a megaproject would be used to recover. The Great Mississippi Flood of 1927 and the 2011 Mississippi River floods are examples.
The cleanup and recovery from the 1980 eruption of Mount St. Helens in rural Washington state was of megaproject proportions.^[11]
Major restoration was necessary after the destruction caused by World War I and II, some of which was paid for by German reparations for World War I and for World War II.

Energy projects

Bar-Boljare motorway	Montenegro	Partial	$3,000,000,000	Construction began on 11 May 2015. The length of the highway is 40.871 km, and the national road standards of Montenegro are adopted, with reference to the European specifications as well. These construction standards will be applied for the two-way four-lane highway, with a speed limit of 100 km/h according to the design, and a construction period of 4 years. The highway stretches from the south to the north across the mountains. It is very demanding, and the construction is very challenging. Bridges and tunnels make up about 60% of the entire route. It is the largest infrastructure project in Montenegro, and the implementation of the project is very challenging. First section between Podgorica and Matesovo opened in July 2022.

Coastal Highway E39	Trondheim to Kristiansand	Under Construction	382,000,000,000kr	$42,400,000,000	The purpose of the project is to replace all the ferry links along the route with fixed connections in order to reduce travel time from 21 hours to 11 hours. The first part, Rogfast has been under construction since 2018 at a cost of $1.9 bn, but the rest is controversial and undecided. Some of the fjords are too deep for pillars or undersea tunnels and too wide for suspension bridges, so floating bridges in untested sizes have been suggested. Initial cost estimates placed the project around 150 bn kroner, but an August 2020 updated estimate moved the cost to 382 bn. A study is underway with the goal of cutting costs, and it is likely the project may be scaled back. There is a decision to evaluate each project separately, making large parts unlikely to be built. Besides Rogfast, two fjord crossings have political go-ahead with construction start around 2029, costing 38 and 24 bn NOK.
