No tunnel is in an alarming, i.e. non-operational, condition. But operating and safety equipment such as cable systems, lighting and signalling in the Neuenhof and Baregg tunnels in canton Aargau were in an alarming condition at the end of 2023. These two tunnels are currently being renovated extensively, Astra said. + Swiss roads are too congested, say survey respondents Almost 9% of the engineering structures such as bridges and galleries showed moderate damage. However, this had no impact on load-bearing and traffic safety. The structural and traffic safety of around 0.7% of the structures in a poor condition is also guaranteed.
