World’s Longest Underwater ‘Megatunnel’ To Cut 21-Hour Coastal Drive Into Half

Human beings have made significant advancements in infrastructure, particularly in constructing long tunnels. One notable example is the tunnel between Lærdal and Aurland in Norway, which is 24.51 kilometres long. Another impressive tunnel is the Yamate Tunnel in Tokyo, Japan, which spans 18.2 kilometres. In New York State, the Delaware Aqueduct stands out at 137 kilometres long. Norway is currently building the world's longest and deepest road tunnel, The Rogfast. Expected to open in 2033, this monumental project will stretch 16 miles and reach depths of 1,300 feet underwater. It will connect the municipalities of Randaberg and Bokn in Rogaland county, Norway.
