Supertunnels Series Premiere (SBS Friday 5 May 2023)
Supertunnels Series Premiere airs Friday 5 May on SBS.
Engineers have dug tunnels that were once thought impossible to cross the oceans and mountains that separate us from our neighbours.
Three massive tunnel construction sites are explored.
Mont-Cenis constructed the first Alpine tunnel in 1871.
The work was expected to take up to 30 years, but it was completed in a fraction of that time thanks to a new pneumatic drill.
When it first opened in 1994, the Euro tunnel was the longest subsea tunnel in the world. Finally, in 1965, the Mont Blanc Tunnel was completed, making it the longest road tunnel in the world at the time.
Supertunnels Series Premiere airs Friday 5 May 2023 at 7.35pm on SBS.
