Technology and nature in harmony when building bridges in southern Norway
In connection with the widening of the E 18 European road in southern Norway, röro staionary and moveable scaffolding systems from thyssenkrupp Infrastructure were used in bridge construction work. The high-performance rentable systems can show their advantages in particular through their modularity, which can be used for large viaducts, freeway overpasses and tunnels.
The European Road 18 (E 18) with a total length of around 1,880 km runs in an east-west direction from Russia to Northern Ireland. It runs from the Norwegian city of Ørje, coming from Sweden, through the south of Norway along the coast to Kristiansand. In order to cope with the steadily increasing traffic volume on this route, the state-owned company Nye Veier AS has decided to construct new sections of the former E 18 with modified routing. Several new bridges and tunnels will be required as part of the new route section. These are, on the one hand, viaducts over which the new E 18 will run and, on the other hand, crossing structures which will allow the new route to be driven over or under. The heart of the construction project is the K 150 viaduct, the Stemmenbrua, which crosses a body of water in a nature reserve. It will be built over a length of around 320 meters using a röro moverable scaffolding system (MSS) from thyssenkrupp Infrastructure.
Stemmenbrua is one of 15 bridge structures that will be built with the load-bearing and advancing scaffolds from Germany for the extension of the European Road E 18.
The HV21 solid wall girders of the feed frame are extended by the truss girders.
The advance into the central 60-meter bridge field marks the end of the bridge construction work.
Die an der höchsten Stelle 55 Meter hohe Stemmenbrua wird als Hohlkastenquerschnitt ausgebildet.
In the middle of the nature reserve the Stemmenbrua with a length of about 320 m is being built.
