Construction of Iron Bridges in Germany

This contract involves the replacement of the existing railway bridge "EÜ Floßgraben" located at railway kilometer 40.3+24 on the route 6298 Neudietendorf – Ritschenhausen, within the Oberhof (Thuringia) - Zella-Mehlis section. The bridge is situated southwest of the Oberhof train station in the Free State of Thuringia, within the district of Schmalkalden-Meiningen. The project requires the construction of a new bridge to ensure the ongoing operational availability of the railway, as the current structure is in poor condition. The new bridge will be designed as a full frame according to Ril 804.4021 and will be founded on a flat base slab. Due to the steep gradient, height adjustments will be incorporated into the base slab. The thickness of the superstructure will be 0.50 m, in line with Ril 804.9040. Additionally, sloped wings will be arranged on both the upstream and downstream sides of the structure, following Ril 804.9030. The length of the inserted element of the bridge will exceed 12.50 m, which is longer than the recommended block length in Ril 804.9040. This deviation is necessary to avoid block joints in the track area and to reduce the required closure periods for inserting multiple blocks.
