In Anras and Assling, two cycle path bridges in wood-concrete-composite construction were built on behalf of the association "Radwege in Osttirol". The two special glulam beams are each 4.1 m wide, and have a length of 32.7 m and 24.7 m, and a thickness of 1.1 m and 0.85 m, and a volume of 125 m³ and 70 m³ respectively. Each supporting structure consists of 17 individual girders, which were block-bonded to form a composite component using a special pressing device. The 25 cm thick concrete slab applied on site is rigidly connected to the wooden supporting structure via milled-in cores and absorbs both the compressive forces in the beam and the structural wood protection.
