Abstract: |
The Visp bypass is an important link on the Swiss national road A9 from Lausanne to Brig-Glis in the Canton of Valais, which is being improved to provide continuous dual carriageway. About 7 km of the alignment of this 8.8 km long section of the A9 will run through tunnels, with the core structures being the 4.2 km Eyholz Tunnel and the 3.2 km Visp Tunnel. Altogether five underground junction structures have to be constructed for the Visp bypass, of which three will be newly excavated and two are enlargements of the existing Vispertal Tunnel. The following report only deals with the Eyholz Tunnel, which has already been largely excavated. Construction of the main contract of the Visp Tunnel is planned to start in 2012. |
