railroad tunnel - online puzzles
A Bering Strait crossing is a hypothetical bridge or tunnel spanning the relatively narrow and shallow Bering Strait between the Chukotka Peninsula in Russia and the Seward Peninsula in the U.S. state of Alaska. The crossing would provide a connection linking North America and Eurasia.
With the two Diomede Islands between the peninsulas, the Bering Strait could be spanned by a bridge or tunnel. There might be one bridge, almost 40 kilometers (25 mi) long, connecting Alaska and the Diomede Islands, and a tunnel connecting the Diomede Islands and Russia. The earth bored from the tunnel could be used as landfill to connect the two islands.There have been several proposals for a Bering Strait crossing made by various individuals and media outlets. The names used for them include "The Intercontinental Peace Bridge" and "Eurasia–America Transport Link". Tunnel names have included "TKM–World Link" and "AmerAsian Peace Tunnel". In April 2007, Russian government officials told the press that the Russian government will back a US$65 billion plan by a consortium of companies to build a Bering Strait tunnel.
History
19th century
The concept of an overland connection crossing the Bering Strait goes back before the 20th century. William Gilpin, first governor of the Colorado Territory, envisioned a vast "Cosmopolitan Railway" in 1890 linking the entire world through a series of railways.
