Description:
The Jägerstieg across the A4 is a so called "true arch bridge", without any additional tension bands between the supports. The curved main beams are made of glulam. This construction allows a span across the complete motorway without any supports in the middle. For the assembly the highway only had to be closed for a few hours. The Jägerstieg is similiar to the first timber bridge over the A4 that was built 2 years before. The bridge fits perfectly in the area which is marked by forests. Not without reason the bridge was recognized and has earned a Thüringen Holzbaupreises reward.
