Biaschina viaduct, Prestressed concrete road bridge in Chironico, Switzerland.
The Biaschina Viaduct spans 525 feet across the Ticino River, reaching a height of 335 feet with its central arch and two smaller spans of 459 feet.
Engineer Christian Menn designed this concrete structure in 1983 as part of the A2 motorway system connecting different regions of Switzerland through the Gotthard Pass area.
The bridge represents Swiss engineering precision through its mathematical design and structural elements, demonstrating the nation's commitment to infrastructure development.
Located 15 miles south of Gotthard Pass, the viaduct serves as the highest bridge on Switzerland's A2 motorway, connecting local communities and facilitating regional transportation.
The structure's location near both the Gotthard rail tunnels and the St. Gotthard Road Tunnel creates a nexus of transportation engineering achievements in the Swiss Alps.
