Simmenfluh Tunnel A6
Weather-proof louvre WSG-50-spec
ASTRA, the Federal Roads Office, modernised the Simmenfluh Tunnel as part of its «Tunnel Safety» project. The 700 metre long Simmenfluh Tunnel was completed in 2003 and is located along the A6 Swiss autobahn (motorway). A 130 metre long escape gallery was built to meet the stricter standards for escape distances. The construction work costs roughly 6.6 million Swiss francs. Several ventilation louvres in special design from Lucoma are installed in the escape gallery.
Weather-proof louvre WSG-50 made of aluminium in special design, semi-circular with a diameter of 2836 mm.
