An underwater tunnel for road and rail links is being built in Europe. It will connect Germany and Denmark. It is known that the corridor will be called "Femarnbelt" and will pass at the depth of the Baltic Sea. Construction is being carried out by a consortium of companies Femern A/S, Ramboll, Arup and Tunnel Engineering Consultants v.o.f. It will set 2 world records at once: the longest immersed tunnel and the deepest tunnel for car and train traffic. Its length is 18 kilometers. The tunnel consists of 79 standard and 10 special sections. Each of the standard sections weighs about 73,000 tons and is 217m long, 42m wide, and 10m high. The underwater corridor will be the shortest route between Scandinavia and the rest of Europe. Travel through it will take only 7 minutes by train or 10 minutes by car, instead of 45 minutes by ferry. The Fehmarnbelt is expected to be completed by 2029. The budget for the tunnel, so far, is about $1,200,000,000. Its planned minimum lifespan is 120 years.
