The STS is pleased to provide you with information about Swiss tunnels.
The Swiss tunnel database contains over 1’250 datas of Swiss tunnels and covers all types of tunnels: road tunnel, rail tunnel, hydropower tunnels and other types of tunnels.
The database was developed in collaboration between the Swiss Tunnelling Society (STS), the Swiss society of engineers and architects (SIA) and the Laboratoire de Mécanique des Roches Ecole Polytechnique Fédérale de Lausanne (EPFL).
If you have questions, please contact the Swiss Tunnelling Society.
The database allows each user to add new projects or make chances in existing project data. Therefore a registration is required. Registration data remain internally. New or mutated data are checked and uploaded after a release.
The STS makes no privacy legal checks of new or mutated data. All sources are to be checked by the applicant and if necessary, the source of the information is to be indicated. See disclaimer.
The STS reserves the right, to decide about new or modified data.
