Beneath the waters of the English Channel lies one of the greatest engineering achievements of the 20th century – the Channel Tunnel , or as it’s often called, the Chunnel .  Stretching 50.45 km between Folkestone (UK) and Sangatte near Calais (France) , it’s the longest undersea tunnel in the world , with 37.9 km of its length running beneath the seabed.  When it officially opened in May 1994 , it redefined what was possible in civil engineering.  Building the Impossible 

Melbourne’s first cable tram began service on the 11 November 1885, running from Spencer Street in the CBD to Bridge Road in Richmond. What began as a marvel of 19-century engineering would become one of the most defining pieces of urban infrastructure in Australia.   The birth of a network  In the late 1800s, Melbourne was booming and required a reliable and efficient transport system to serve the rapidly growing population.  Melbourne’s cable tram system was created by Fran

On November 7, 1940, just four months after it opened, the Tacoma Narrows Bridge in Washington State collapsed in spectacular fashion. A steady 67km/h wind sent the elegant suspension bridge into violent oscillations until its mid-span tore apart and fell into the Narrows below. No lives were lost that day, but the event shook the engineering world. The collapse became one of the most famous failures in modern history – captured on film, studied in classrooms, and referenced
