In autumn 2018, a storm destroyed the old “Nöbliger Steg” Bridge over the river Gail. For around two and a half years, the community of Dellach had to make do without their much-needed footpath to school and church, so they campaigned for the reconstruction of the bridge. For safety reasons, a new location was chosen 300 metres downstream. In order to avoid damaging the bridge again, the safety concept ensures that an extra distance of two metres is maintained between the water and the underside of the bridge, calculated from the maximum assumed high water level. The new bridge has a span of around 38 metres and weighs around 25 tons. The timber frame construction consists of large-format glulam components. Only the bottom chords are made of steel. The bridge is supported by concrete abutments.
CLTPLUS in the roof
All visible parts of the bridge are made of wood. The walkway is made of larch boards. The overhanging roof is designed as a flat pitched roof with a 5° pitch. It not only protects bridge users from rain, but the wooden structure is also protected from the weather by the metal-covered, overhanging roof. The regional company Holzbau Pichler assembled the individual structural elements in their own factory. Theurl supplied the unprocessed CLTPLUS panels. Two different quality standards were used: the part of the roof that is visible from below was manufactured to Industry+ standard, while the hidden areas under the roof covering used Industry standard. The high-quality CLTPLUS, constructed in several cross-glued layers, can bridge large spans and is therefore the right choice for the roof structure. Prefabrication in the factory ensured that construction of the roof could be completed quickly and protect the bridge against water ingress.
