The tunnel was opened in 1999 and consists of two tubes of 2,460 metres (8,070 ft) in length. In a tunnel test by the European Tunnel Assessment Programme (EuroTAP) in 2005 it was rated as "good" – the second-highest grade out of five.[1]
The two tubes consist of four linked tunnels, namely,
- Alusuisse — 1,070 metres (3,510 ft),
- Contoured — 620 metres (2,030 ft),
- Crête Plane — 180 metres (590 ft), and
- Ancien Sierre Plant Composition — 580 metres (1,900 ft).
The Sierre Tunnel came to international attention in March 2012 after a coach crash inside resulted in the deaths of 28 people, including 22 children, who were returning to Belgium from a school skiing holiday.[2]
