The Gotthard Road Tunnel opens in Switzerland as the world's longest highway tunnel at 10.14 miles (16.32 km) stretching from Göschenen to Airolo.
On September 5, 1980, Switzerland opened the Gotthard Road Tunnel, the world's longest highway tunnel at over 16 km.
The Gotthard Road Tunnel stretches 10.14 miles (16.32 km) through the Swiss Alps, linking Göschenen and Airolo. Its construction spanned nearly a decade, overcoming complex geological formations and water ingress challenges. Engineers implemented advanced tunneling methods and rigorous safety protocols. The tunnel provided a year-round, low-gradient route across the Alps, significantly reducing travel times for commerce and tourism. It features emergency exits, ventilation systems, and monitoring technology for accidents. Since opening, the Gotthard Tunnel has become a vital artery in Europe's transportation network and a marvel of civil engineering.
