Yes, I think. Jillian
The world's longest railroad tunnel is the Seikan Tunnel, it is 33.49 miles long.
Tunnels are underground passages that are completely enclosed except for the entrance and exit. The longest road tunnel in the world is the Laerdal Tunnel, running over 80,000 feet. The fifth longest is the Hsuehshan Road Tunnel extending over 43,000 feet.
The Seikan Tunnel is 14.5 miles long, being one of the longest tunnels in the world.
The Channel tunnel (actually twin tunnels) is a railroad tunnel, the second-longest the world . There is no road inside save for the third tunnel, which is a single carriageway escape tunnel (special emergency vehicles, able to drive in either direction, were designed for this safety tunnel)
The Channel Tunnel, which connects the UK and France, is approximately 50.45 kilometers (31.4 miles) long, making it one of the longest underwater tunnels in the world. In comparison, the Severn Tunnel, which runs under the River Severn in the UK, is about 7.0 miles (11.2 kilometers) long. Therefore, the Channel Tunnel is significantly longer than the Severn Tunnel, being over four times its length.
The world's longest canal tunnel is the Rove Tunnel in France. The Stad Ship Tunnel in Norway is shorter, wider, and deeper.
Alas, no. There are several longer. The longest of all, the Paijanne water tunnel in Finland, is a water supply tunnel so probably doesn't count. The Seikan tunnel in Japan carries a narrow-gauge railway and is 33.5 miles long. The Channel tunnel is certainly the longest full-size railway tunnel at 31.3 miles. However, those crafty Swiss are currently at work under the Alps, and the Gotthard Base tunnel (also a standard gauge railway) will be 35.5 miles long, a clear winner.
The longest rock tunnel in the world is located in the New York City.
World's longest tunnel situated in New York state, United States named Delaware Aqueduct tunnel
The world's longest canal that is also a tunnel is the Rove tunnel located in France. It was built in 1974. The longest tunnel in the world is a railroad tunnel that is 35 miles long through the Swiss Alps.
The word 'chunnel' was a media generated word in the 1980's and is no longer used. It was an amalgamation of 'channel' and 'tunnel'. Work on the Channel Tunnel started in 1988 and the first trains went through the tunnel in 1994. It is the longest undersea tunnel in the world although not the longest tunnel overall.
The Seikan Tunnel is in japan. it is one of the longest in the world.
