Bridge–tunnel
A bridge–tunnel is a persistent, unbroken road or rail connection across water that uses a combination of bridges and tunnels, and sometimes causeways, and does not involve intermittent connections such as drawbridges or ferries. Bridge–tunnels are a form of fixed link or fixed crossing which replaces ferry service. Fixed links are often, but not necessarily, intercontinental links between continents or transoceanic links to offshore islands. Tunnels and bridge–tunnels For water crossings, a tunnel is generally more costly to construct than a bridge. However, navigational considerations at some locations may limit the use of high bridges or drawbridge spans when crossing shipping channels, necessitating the use of a tunnel. Examples of such tunnels include the Downtown Tunnel and Midtown Tunnel under the Elizabeth River between Norfolk and Portsmouth, Virginia in the United States, the George Massey Tunnel in Greater Vancouver, Canada Canada is a country in No ...

Great Belt
The Great Belt ( da, Storebælt, ) is a strait between the major islands of Zealand (''Sjælland'') and Funen (''Fyn'') in Denmark. It is one of the three Danish Straits. Effectively dividing Denmark in two, the Belt was served by the Great Belt ferries from the late 19th century until the islands were connected by the Great Belt Fixed Link in 1997–98. Geography The Great Belt is the largest and most important of the three Danish Straits that connect the Baltic Sea to the Kattegat strait and Atlantic Ocean. The others are the Øresund and the Little Belt straits. The Great Belt is long and wide. It flows around two major islands: Samsø in the north and Langeland to the south. At Sprogø the Great Belt divides into the East Channel and the West Channel. Both are traversed by the Great Belt Fixed Link, but a tunnel also runs under the East Channel. Geology In pre-glacial times a river, which the Baltic Sea basin then contained and which geologists call the Eridanos, must ...

Great Belt Fixed Link
The Great Belt Bridge ( da, Storebæltsbroen) or Great Belt fixed link ( da, Storebæltsforbindelsen) is a multi-element fixed link crossing the Great Belt strait between the Danish islands of Zealand and Funen. It consists of a road suspension bridge and a railway tunnel between Zealand and the small island Sprogø in the middle of the Great Belt, and a box-girder bridge for both road and rail traffic between Sprogø and Funen. The total length is . The term ''Great Belt Bridge'' commonly refers to the suspension bridge, although it may also be used to mean the box-girder bridge or the link in its entirety. Officially named the East Bridge, the suspension bridge was designed by the Danish firms COWI and Ramboll, and the architecture firm Dissing+Weitling. It has the world's sixth- longest main span ().

Tokyo Bay Aqua-Line
The , also known as the Trans-Tokyo Bay Expressway, is an expressway that is mainly made up of a bridge–tunnel combination across Tokyo Bay in Japan.

With an overall length of 23.7 km, it includes a 4.4 km bridge and 9.6 km tunnel underneath the bay—the fourth-longest underwater tunnel in the world. Overview An artificial island, , marks the transition between the bridge and tunnel segments and provides a rest stop with restaurants, shops, and amusement facilities. A distinctive tower standing above the middle of the tunnel, the Kaze no Tō (の, "the tower of wind"), supplies air to the tunnel, its ventilation system powered by the bay's almost-constant winds. The ¥1.44 trillion (US$11.2 billion) roadway opened December 18, 1997, after 23 years of planning and nine years of construction. The Tokyo Bay Aqua-Li ...

Subterranean River
A subterranean river is a river that runs wholly or partly beneath the ground surface – one where the riverbed does not represent the surface of the Earth. It is distinct from an aquifer, which may flow like a river but is contained within a permeable layer of rock or other unconsolidated materials. A river flowing below ground level in an open gorge is not classed as subterranean. Subterranean rivers may be entirely natural, flowing through cave systems. In karst topography, rivers may disappear through sinkholes, continuing underground. In some cases, they may emerge into daylight further downstream. The longest subterranean river in the world is the Sistema Sac Actun cave system in Mexico. Subterranean rivers can also be the result of covering over a river or diverting its flow into culverts, usually as part of urban development.Richard J.

Land Reclamation
Land reclamation, usually known as reclamation, and also known as land fill (not to be confused with a waste landfill), is the process of creating new land from oceans, seas, riverbeds or lake beds. The land reclaimed is known as reclamation ground or land fill. In some jurisdictions, including parts of the United States, the term "reclamation" can refer to returning disturbed lands to an improved state. In Alberta, Canada, for example, reclamation is defined by the provincial government as "The process of reconverting disturbed land to its former or other productive uses." In Oceania, it is frequently referred to as land rehabilitation. History One of the earliest large-scale projects was the Beemster Polder in the Netherlands, realized in 1612 adding of land. In Hong Kong the Praya Reclamation Scheme added of land in 1890 during the second phase of construction.
