Trough Bridge Kirchzarten

In this case a new bridge construction was economically advantageous compared to a renovation of the existing bidge. The trough bridge replaces a timber construction which did not have a sufficient protection from weathering and the required load capacity could not be guaranteed anymore. The client decided to commission a new timber bridge instead of a renovation. The existing bridge could be dismantled and the new bridge assembled within a single day. Due to this process the walkway did not have to be closed for more than one day and also the road was blocked for only a few hours. Contrary to the old construction the new bridge is laterally covered with larch so that the glulam beams are protected from weathering.
