The Channel Tunnel (French: Le tunnel sous la Manche), also known by the portmanteau Chunnel, is a 50.5 km (31.4 mi) undersea rail tunnel linking Folkestone, Kent in England with Coquelles near Calais in northern France beneath the English Channel at the Strait of Dover. At its lowest point it is 75 m (250 ft) deep. It has the longest undersea portion of any tunnel in the world, although Japan's Seikan Tunnel is longer overall at 53.85 km (33.5 mi) and reaches a depth of 240 m (790 ft).
The tunnel carries high-speed Eurostar passenger trains, Eurotunnel ro-ro vehicle transport and international rail freight trains. In 1996 the American Society of Civil Engineers identified the tunnel as one of the Seven Wonders of the Modern World.
