With such a population that is increasing day by day, the needs are also growing up. That’s why the idea of constructing the tunnel helped as a medium to overcome the problems created by the means of transportation. It is generally an underground pathway that is helpful in those areas where the traffic seems to be very high. Because of that a person can easily reach their places where he/she want to reach without so much of congestion issue in a shorter time. The tunnels are made to control the unpredictable traffic. These are generally made to control rail traffic and vehicular road traffic. We are going to discuss here top 10 strangest tunnel in the world.

The Tokyo Bay Aqua Line is a combination of bridge and tunnel across the Tokyo Bay in Japan. Sometimes it is also known as Trans-Tokyo Bay Highway. The city of Kawasaki in Kanagawa Prefecture is connected with the city of Kisarazu in Chiba Prefecture, and emerge the parts of National Route 409. It has the overall length of 14 km; comprise 4.4 km bridge and 9.6 km of tunnel under the bay which is the fourth longest underwater tunnel in the world. Its construction begun in 1989 and got a start in the year 1997 with a cost of 1.44 trillion yen. There is an artificial island situated in the crossover of the bridge-tunnel point called Umihotaru. The Tokyo Bay reduced the drive between Chiba and Kanagawa from 90 to just 15 minutes because of this strangest tunnel.

The Thames Tunnel is an underwater tunnel which is built under the River Thames in London connecting Rotherhithe and Wapping. This strangest Tunnel is about 35 feet wide and 20 feet high and 1,300 feet long, partially built at a depth of 75 feet below the river surface measured at high tide. It is known to be the first constructed underneath river tunnel. The work started for the tunnel in the year 1825 which completed in 1843 by the help of newly invented tunneling shield technology. It now forms the part of London Overground Railway Network under the Transport for London. It was originally designed basically for horse-drawn carriages, but never used for that purpose.

The Tunnel thus connected end-to-end with the LGV Nord and High Speed 1 (HS1) high-speed railway lines. It also carries high speed Eurostar passenger trains and international freight trains. The construction started in 1988 and it opened in the year 1994.

However the Channel Tunnel is having the longer undersea section. This strangest tunnel is also the second deepest and the longest main-line railway tunnel after the Gotthard Base Tunnel. The Seikan Tunnel was successfully started in the year 1988 and the estimated cost was calculated 538.4 billion yen in the construction.

The main purpose to build this strangest tunnel and the Zion Mount Carmel Highway was to bring a direct way to Bryce Canyon and Grand Canyon from Zion National Park. Before the year 1989, many of the large vehicles like tour buses, trailers and motor homes were affected in leading problems by accidents. That’s why, to resolve this issue the National Park Service begun traffic control in the spring of that year and large vehicles were allowed only in a limited time based upon running season.

The Gotthard Base Tunnel is a railway base tunnel that is built through the Alps in Switzerland. The Tunnel has the route length of 57.09 km and overall 151.84 km persisting tunnels, shafts and passages. It got the start in June 2016 and began with full services on December 11th, 2016. This strangest Tunnel is proved to be the world’s longest and the deepest traffic tunnel and the first flat and low-level route through the Alps. The whole project persists of two-single track tunnels which connects Erstfeld and passes through Bodio below Sedrun. The main aim behind constructing this strangest tunnel was to increase the local transport capacity through the alpine barrier, especially for the bulk transport and more importantly to shift freight volumes from trucks to freight trains. This helped in reducing the danger of fatal road crashes and somehow the environmental damage created by the amount of freight managed by heavy trucks. The total project consisted of $12 billion.
