English Channel Underwater Tunnel

Flanked by two powerful nations, the English Channel has long been one of the world’s most important maritime passages. Yet for most of its history, crossing was a dangerous prospect. Engineers proposed numerous plans for spanning the gap, including a design for an underwater passage more than twice the length of any existing tunnel.

How was the Channel Tunnel built underwater? Engineers used two systems of tunnel linings – cast iron segments bolted together and precast concrete rings. The TBMs excavated a huge amount of chalk. On the French side, the chalk was crushed, mixed with water, and pumped inland behind a specially built dam 37m high. The project required two tunnels, each over a mile long, to pass under the bay’s shipping channels. Tunnel boring machines were used to excavate these tunnels, and then precast concrete sections were submerged and connected underwater. This ensured the tunnels’ structural integrity and minimized disruption to shipping The Channel Tunnel (often called the ‚Chunnel‘ for short) is an undersea tunnel linking southern England and northern France. It is operated by the company

When England and France decided to link their two countries with a 32-mile rail tunnel beneath the English Channel, engineers were faced with a huge challenge. Not only would they have to build The Channel Tunnel—commonly known as the “Chunnel”—is one of the most impressive engineering feats of the modern era. That’s not just our subjective opinion either; it was named one of the Seven Wonders of the Modern World by the American Society of Civil Engineers. The ASCE refers to it as “engineering magic” and they have a point – constructing The Chesapeake Bay Bridge–Tunnel (CBBT, officially the Lucius J. Kellam Jr. Bridge–Tunnel) is a 17.6-mile (28.3 km) bridge–tunnel that crosses the mouth
