Taking a Turn: Danube Arch in Hungary

The focus of this article is the engineering of the main span of a new bridge over the Danube River, just downstream from Budapest, Hungary. The new crossing is part of the M8 Motorway project, which began in 2002 under the planning and direction of Hungarian National Motorways. The bridge is scheduled to open by mid-2007 and is planned to be Hungary’s main east-west link between Austria and Romania, going directly through the middle of the country. The bridge consists of two approach viaducts over the flood plain, with the central arch span measuring 1,683m, considered to be a world record. A variety of different techniques have been used in the construction. Due to its length and proximity to power lines, a cable-stayed bridge with towers proved to be impractical for this bridge, limiting the choice of design options. The author notes that in the selection of the arch design, the main benefit has been the ability to build on the side of the river and float the arch span into place, with minimal disruption to river traffic and maximum safety to site personnel. The author describes in detail the procedure used to place the central arch span into position.
