Wooden wildlife bridge is erected



Switzerland's first wildlife bridge made of wood quickly takes shape. The assembly of the wooden beams takes another week. Since 1998 Timbatec has been committed to the realization of such structures from the natural raw material wood. Today it is finally reality!

Transport routes cut through the habitats of wildlife. A 50-metre wide arched wooden structure will soon enable deer and wild boars to cross the A1 motorway safely. Construction workers are currently assembling the over 17-metre long wooden beams.

In order not to disrupt traffic too much, the work is carried out at night.

Long preparation  

Timbatec has been committed to wooden wildlife bridges for over twenty years. In 1998 Timbatec showed in a basic report that wood as a local raw material is a cost-effective and ecological alternative for green bridges. In 2005 the Department of Construction, Transport and Environment of the Canton of Aargau commissioned moser+colombo architektur gmbh and Timbatec with a concept study. The result was clear: wildlife overpasses over motorways can easily be realised with a timber supporting structure despite high earth loads and impact forces.    

Bericht WTK 1998

We are proud that we were able to plan Switzerland's first wildlife overpass in timber construction together with Bänziger Partner AG. And we are looking forward to many more wildlife bridges made of wood. Because: there are still many motorways that cannot be crossed by deer and wild boars. And there is a lot of wood which could be used to build the bridges.
