Because traffic routes cut through the habitats of wild animals, the Federal Office for the Environment defined wildlife corridors of supraregional importance. The corridor "AG6" runs between Gränichen and Suhr over the A1 national road. A 50-metre wide arched wooden structure enables wildlife to cross the motorway safely. Around 70,000 vehicles pass the wildlife bridge every day. The entire wooden construction was erected within a total of 15 nights, during which one lane was completely closed to traffic at a time. The entire assembly went exemplary and smoothly and could be completed 9 days earlier than planned. Thanks to the use of 640 m³ glulam and 2150 m² laminated veneer panels, 1000 tons of CO2 could be saved compared to the conventional concrete construction method.
