  • Completed 1959
  • In-operation
Following the route of the Saint Lawrence River, it allows access to the centre of the continent from the ocean by shipping. When combined with the New York State Canal System, it has a second access to the ocean at Long Island Sound / Hudson Estuary, turning New England into a virtual island. When combined with the Illinois Waterway, it can reach the Gulf of Mexico from the Great Lakes, turning the entire East Coast and Midwest of the United States into a virtual island.

Mississippi River System Central United States In-operation
  • Gulf of Mexico
  • Great Lakes
 Channelizing the Mississippi River and major tributaries/distributaries, it accesses central North America. With the Saint Lawrence Seaway it reaches the Gulf of Saint Lawrence, and turns the Midwest and East Coast of the United States into a virtual island.

Unified Deep Water System of European Russia Russia In-operation
  • Baltic Sea
  • Black Sea
  • Caspian Sea
  • White Sea
 Traversing across European Russia, the shipping waterway accesses the Atlantic and Arctic Ocean basins, and combined with the Suez Canal, accesses the Indian Ocean as well.

Eurasia Canal
(Caspian Canal)		 Caucasus Proposed
  • Caspian Sea
  • Black Sea

Iranrud
(Caspian Canal)		 Iran 35°41′N 51°25′E / 35.683°N 51.417°E / 35.683; 51.417 Proposed

  • Indian Ocean (Persian Gulf or Gulf of Oman)
 Russian plan for independence from the Bosphorus, Straits of Gibraltar, Suez Canal; by digging a canal to connect to the Indian Ocean from the Caspian Sea. through the Iranian Plateau and Iran; needing to cross mountains over 1,600 m (5,200 ft) high and being over 1,400 km (870 mi) long.
