Trans Global Highway
Encyclopedia
The Trans-Global Highway is a proposed highway system that would link all continents of Earth except Australia and Antarctica. The highway would network new and existing bridges and tunnels, improving not only ground transportation but also potentially offering a conduit for utility pipelines. It was proposed by Frank X. Didik.

William Gilpin was a 19th century U.S. explorer, politician, land speculator, and futurist writer about the American West. He served as military officer in the United States Army during several wars, accompanied John C. Frémont on his second expedition through the West, and was instrumental in the...

s of the type that was employed in the construction of the Channel Tunnel. The three tunnel proposal is considered by many to be preferable over a bridge due to severe environmental conditions, especially the inescapable winter ice damage.

Each proposed tunnel would be shorter than some current tunnels. The Channel tunnel linking England with mainland Europe is approximately 31.34 miles (50.45 km) long; the ocean tunnel Seikan linking Hokkaidō

To make a bridge or tunnel useful, a road must be built to connect it, despite very difficult terrain and climate. In Alaska a 700 miles (1,100 km) road would be needed, and in Russia a road more than 1,200 miles (2,000 km) long must be constructed.

), which would only be 4.2 miles (7 km) long. Moreover, Sakhalin Island region is a major oil-producing region, and the introduction of a pipeline would add a valuable secondary means of oil transport.

Gibraltar Tunnel

The Gibraltar Tunnel is proposed to be a rail tunnel linking Africa and Europe. Due to the depth of the Strait of Gibraltar (300–900 metres / 1000–2950 feet), it would be a great challenge to remove automobile exhaust from this depth. Any tunnel would most likely be an electrified rail tunnel, similar to the Channel Tunnel linking the UK and France. There have also been proposals for a bridge over the Strait.

, and foot, dealing with jungle, swamp, insects, and other hazards.

Some people, groups, indigenous populations, and governments are opposed to completing the Darién portion of the highway. Reasons for opposition include protecting the rain forest, containing the spread of tropical diseases, protecting the livelihood of indigenous peoples in the area, and reducing the spread of drug trafficking and its associated violence from Colombia.

Difficulties

As with all major public works projects, funding is an issue. Large international projects such as the Bering Strait crossing, Japan–Korea Undersea Tunnel, and Strait of Gibraltar crossing

 would be compatible with the proposed tunnels.

Despite the hypothetical benefits of a global transport link, there is currently no publicised reasoning that would justify the massive financial cost of such a proposal.
