The Channel Tunnel

The Channel Tunnel, also known as the Eurotunnel, is an undersea rail tunnel connecting England and France beneath the English Channel. Measuring about 31 miles (50 km), it allows passenger trains, freight trains, and vehicles to travel between Folkestone in England and Calais in France efficiently. Built through extensive engineering work beneath the seabed, it provides a vital link that promotes trade and travel between the two countries. The tunnel ensures a faster, more reliable connection compared to ferries, and its construction involved innovative technology and international cooperation, making it one of the most impressive engineering feats of the 20th century.
