The tunnels are planned to consist of two 28-foot (8.5 m) diameter tunnels. [2] At 13 miles (21 km) long the main tunnel is expected to become North America’s longest rail tunnel, surpassing the Mount Macdonald Tunnel in British Columbia. [1] [2] An additional 1.5-mile (2.4 km) rail tunnel is planned to be constructed to the west. The tunnels ...
The tubes stretch 9,117 feet (2,779 m) from portal to portal, [4] making them the longest continuous underwater vehicular tunnels in North America. [ 5 ] [ 6 ] At the time of its opening, the Brooklyn–Battery Tunnel was the longest underwater vehicular tunnel in the US and the second-longest in the world, behind the Queensway tunnel under the ...

A transatlantic tunnel is a theoretical tunnel that would span the Atlantic Ocean between North America and Europe possibly for such purposes as mass transit. Some proposals envision technologically advanced trains reaching speeds of 500 to 8,000 kilometres per hour (310 to 4,970 mph). [ 1 ]
