Eurotunnel channel

The Eurotunnel, a 50 km underwater rail tunnel linking France and England, revolutionized transport between continental Europe and the United Kingdom since its opening in 1994.

About this subject

The Eurotunnel, officially known as the Channel Tunnel, is one of the greatest engineering feats of the 20th century. Spanning 50.45 km, with 37.9 km under the seabed of the English Channel, it is the longest underwater tunnel in the world. Construction began in 1988 and took six years, employing about 15,000 workers. The tunnel's maximum depth reaches 75 meters below the seabed.

The structure consists of three tunnels: two main rail tunnels (one for each direction) and a central service tunnel. High-speed Eurostar trains cover the journey between London and Paris in about 2 hours 15 minutes, while freight trains transport goods. Before the tunnel, the only options were ferry or air travel. On average, 400 trains pass through the tunnel daily, carrying passengers, vehicles (via the Le Shuttle service), and freight.

Interestingly, the idea of a tunnel under the English Channel dates back to 1802, when engineer Albert Mathieu proposed a plan to Napoleon. However, geological and political difficulties delayed its realization for nearly two centuries. The white chalk of the English Channel, known as 'clay-with-flints', proved ideal for excavation, facilitating the work of tunnel boring machines (TBMs).

The Eurotunnel not only shortened travel distances but also economically integrated the United Kingdom with continental Europe. It is operated by the company Getlink (formerly Eurotunnel Group) and, in 2023, recorded over 20 million passengers. Despite issues such as fires in 1996 and 2008, the tunnel maintains an excellent safety record.
