The Swiss Federal Roads Office (FEDRO/ASTRA) intends increasing safety in the 3.2 km long Belchen Tunnel on the A2 motorway. Towards this end it has invested 128 million Swiss francs since 2008. The focus has been on the construction of new ventilation tunnels, installing powerful axial fans and renovating the operating and safety systems. Fire protection plates were to be installed in both two-lane bores by early 2015 with one bore having to be closed with traffic diverted through the other one. The plates were installed using the Tunlift, a self-propelling working platform.
